Caution: Even when a COMPACT has been completely disconnected, there can still be deadly voltages present at 

the OUTPUT. To remove these voltages you must switch the COMPACT ON with the ON/OFF switch. After one 

minute the electronics are discharged and any work can now be safely carried out. 

Caution: In normal use lead-acid and lead-gel batteries give out explosive gases. Never smoke or allow a spark or 

flame in the vicinity of batteries. The batteries must always be stored or placed in a well ventilated area, they should 

be placed in such a way that there is no danger of short circuiting through carelessness. Never charge frozen batteries. 

The COMPACT is not to be used or sold for life support equipment or applications. 

Special Precautions 

• While working on batteries there should always be a second person close to you or within your voice range, in case 

help is needed. 

• Plenty of fresh water and soap must be ready at hand so that in case of acid coming in contact with skin , eyes and 

clothes, the areas in question can be thoroughly washed. 

• If acid enters the eyes, you must thoroughly wash the eyes with cold running water for at least 15 minutes. It is recommended 

that you immediately consult a medical doctor. 

• Baking powder neutralizes battery acid electrolyte. Always keep some at hand. 

• Special care must be taken when working with metal tools near or on the batteries. With tools such as screwdrivers, 

spanners etc. short-circuits can result. Sparks produced by the short-circuit can cause an explosion. 

• When working on batteries all personal metal items such as rings, necklaces and bracelets must be removed. Batteries 

are so powerful that short-circuit with these items can melt them and thus cause severe burns. Always follow the 

battery manufacturers instructions. 

• Under certain conditions your COMPACT or a connected generator can start automatically. While working on an 

electrical installation you must ensure that these appliances are disconnected before commencing any work.

Description of main functions 

1. The Inverter 

The sinewave-inverter section of your COMPACT generates a sinewave AC voltage with an exceptionally precise voltage 

and stabilized frequency. In order to start large electric motors , the user has the possibility to employ a short-start-power 

which is 3-times the nominal power of the COMPACT. 

The inverter is protected against overload and short-circuit. A power-stage with the latest MOS-FET power transistors, a 

toroidal transformer, and a fast regulating system make-up a robust and reliable inverter with very high efficiency. A 1-20 

Watt adjustable load detection system serves to provide the smallest energy consumption and ensures a long life for the 

battery. 

2. The Transfer system 

COMPACT can be connected to an AC input source. For example a stand-by motor generator or the AC grid, such as shore 

power or a caravan park. With the transfer system, on one side you have AC voltage which is used to run the load, on the 

other side the batteries are being charged. The distribution of energy between the AC loads and battery charger is automatic. 

3. The Battery charger 

The built-in battery charger is capable of charging the batteries quickly and completely. A microprocessor controlled, 3 to 

4 Step charging process ensures the optimum charging of the batteries. The desired charging current can be set continuously 

from 0 – 55A (SSC-48-3K5 0 - 50A). The battery charger can be used for lead-acid or gel batteries. Thanks to the floating 

charge ability of your Compact, the batteries can remain continuously connected. 

4. The solar charge regulator (SSC-xx-xxx-s models only) 

With the built-in solar regulator, the COMPACT is a complete solar-power-center. In a solar installation this regulator ensures 

that the batteries are charged correctly. With the COMPACT, batteries can be charged with a generator and with the 

solar modules at the same time. The charging of batteries with both energy sources is carried out fully automatically. 

5. Remote control (optional) 

A remote display can be connected to your COMPACT. All operating elements and displays with the exception of the load 

detection level adjustment are available on the remote control. The remote control is supplied with a 20m long cable. This 

cable can be up to 40m long. On the remote control output power and charging current are also shown. 

Battery connections 

Lead-acid batteries are normally available in blocks of 2V, 6V or 12V . In most cases, to generate the necessary operating 

voltage and the capacity of the batteries for the COMPACT many batteries have to be connected together in parallel and or 

in series. Following three examples are shown: 

1. Parallel Connection: Maximum 2 batteries in parallel.

Location 

INSTALLATION 

The location of the COMPACT must be chosen by the following criteria: 

• Protection from unauthorized handling. 

• Dry dust free room, no condensation, no rodents. 

• Never install directly over the battery and never in a cabinet together with the batteries. 

• Keep ventilation holes free. The ventilation of the COMPACT is designed in such a way that it will work most efficiently 

when mounted vertically. 

• In mobile installation it is important to keep vibrations to a minimum. 

Mounting 

1. Compact 

The COMPACT can be installed in any desired location. It is preferred that the appliance be wall mounted with battery cables 

downwards. The COMPACT is fixed on the wall with four screws through the four holes (dia. 5.5mm) which are accessible 

from the outside. In motor vehicles, the COMPACT must be fixed on vibration reducing mounts. The COMPACT 

must not be fixed on a combustible wall, as the back of the casing can get hot and reach up to 80 degree Celsius. 

2. Protection cover IP23 

To reduce the chance of foreign objects entering the Compact or condensation 

from a steel roof, you should use the IP23 cover (Part No SSC-IP23-01) 

this is easily installed after fixing the COMPACT to the wall. To do this, 

release slightly the mounting screws of the Compact, it’s then possible to 

pass the IP 23 cover between the COMPACT and the wall. The cover must 

touch the top screws. Retighten the 4 screws. It’s ready. 

Connection 

1. General instructions on connecting 

The cable connection on the terminals AC INPUT / AC OUTPUT / 15A 

230VAC are carried out with a No 1 screwdriver, the connection on the SO- 

LAR terminal with a No 2 screwdriver. 

The conductor cross section on the terminals AC INPUT / AC OUTPUT / 15A 

230VAC of the connecting cable must be minimum. 2.5mm 2 . 

All connecting cables and also the mounted battery cables , must be fixed with strain relief clamps. 

The COMPACT is delivered with battery cables already connected. 

The battery cables must never be extended. If the extension is unavoidable then the conductor cross section must be increased, 

contact your installer for this calculation. 

To protect the battery cable, a fuse corresponding to the conductor cross section must be fixed directly on to the battery. 

All cables must be tightly screwed in place. For safety, a yearly maintenance program is recommended. In mobile installations, 

maintenance must be carried out more often. 

Connections must be done by qualified personnel. Material such as cable, connectors and distribution boxes, fuses 

etc. used in the installation must comply with the respective valid low-voltage installation rules and regulations

Cabling/wiring 

When making connections to the Compact you must ensure that all connections are carried out in a clean and correct manner and under no 

circumstances that a cable is connected to a wrong terminal. 

Connecting the COMPACT must be carried out in the following order. 

(a) Pre-installation settings 

Before you start with the wiring of the COMPACT you must set the type of battery. If sealed-gel batteries are used then you must set the 

small slide-switch ”Equalize“ which is on the front with the connecting terminals, to OFF position. In case of normal lead-acid batteries, 

these can handle a higher equalizing charge, the same slide switch can be set to the ON position. If in doubt leave the setting in the OFF 

position. 

(b) Connection to battery 

Prepare the batteries for connection. Prepare battery cables, if necessary press on cable tabs/shoes. Connect the red cable to the Battery 

positive fuse/circuit breaker and the black cable to battery Minus(-) Take care when connecting the second cable to the battery, as a spark 

is produced, this is caused for a short time due to high current flowing in the COMPACT to charge the capacitors. This is another reason to 

install a battery fuse/circuit breaker. For this reason follow strictly the safety measures described in this manual. 

DO NOT INSERT THE BATTERY FUSE AT THIS STAGE. 

(c) Connection to the AC OUTPUT 

The AC output must be connected to the screw terminal AC OUTPUT. For this, use a 3-core cable with a conductor cross section of 

2,5mm 2 . Connections are marked as follows “N“= Neutral, “PE“= Earth, “L“= Live or Active. 

Caution: High voltage can be at the AC output, ensure the Compact is not connected when making AC connections 

(d) Connection to the AC INPUT 

The AC input supply from the electricity grid or from a generator must be connected to the screw terminals marked AC INPUT. For this 

use a 3-core cable with a conductor cross section of 2,5mm 2 . Connections are marked as follows “N“ =Neutral, “PE“= Earth, “L“ = Live/ 

Active. 

(e) Connect the Solarmodules: SOLAR +/- (Only for solar option) 

Solar modules are connected on these terminals. Under no circumstances should any other energy source i.e. wind generator be connected 

to these terminals. Depending on the power of the modules, the cable cross section should be 2.5 up to 6mm 2 . Before connecting it is 

necessary to check with a Voltmeter that the voltage of the Module meets the following values: 

SSC-12-1K3S 17-25V /30A, 

SSC-24-2K3S 34-45V /30A, 

SSC-48-3K5S 68-90V /20A. 

(f) Connection to Auxiliary Contact 

On these three terminals is a potential free change-over contact capable of switching a maximum current and voltage of 16A/250Vac. The 

“Contact active” LED shows the status of these contacts, when the LED is ON, the contacts are active. The schematic view of the connections 

on the front of the Compact, shows the contacts in the non active state. 

(g) Connection to Remote display 

The Remote Display SSC-REM-01 is connected in the terminal marked “Remote control“ with a RJ11/8 connector. The Remote Control 

can be plugged IN at any time. Push in the connector, without forcing it, until you hear the „click“, now the connector is locked in place. 

The same applies to the plug at the Remote Display end. The length of the cable for the Remote Display should not exceed 40m, is comes 

standard with 20m cable. 

(h) Connection to Temperature Sensor (Optional.) 

The Temperature sensor SSC-TS-01 is connected to the terminal marked “Temp“ with a RJ11/6 connector. The Temperature Sensor can 

be plugged IN at any time. Push in the connector without forcing it, until you hear a click, now the connector is locked in place. The Temperature 

Sensor should be glued or taped to the wall of the battery or near it. The Temperature Sensor cable must not be tied together with 

the battery cables or laid in a cable bundle. 

OPERATING 

You can now apply power to your compact by inserting the battery fuse: 

Caution: this will generate a spark. 

Check if the “OFF” LED is lit. If it is not lit, press quickly the “ON/OFF” switch, now “OFF” should be lit. 

On connecting the battery the COMPACT needs 1 – 2 Minutes to calculate the actual State of Charge of the battery. During this time the 

battery State of Charge is shown as 100% charged. (LED 14,15,16 &17 lit). 

If the LED marked “Battery Low/High” is lit, the battery charge is too low. If the LED marked “Battery Low/High” is blinking, the battery 

charge is too high. 

Caution: With a wrong battery voltage the COMPACT can be destroyed. ( For example: connecting a SSC-12-1K3 to a 48V Battery). 

If the COMPACT has been connected with reverse battery polarity, it must be returned to Solar Energy Australia for repair.

The Inverter 

The Inverter section of the COMPACT produces a high quality Sinewave output, the quality of this output is compatible 

with any appliance. Thanks to the generous dimensioning of the COMPACT, you can operate appliances requiring higher 

power than the nominal power of the COMPACT for a short time. The COMPACT provide up to 3-times the nominal 

power to start motors etc. 

The Inverter mode is displayed through LED marked “Inverter” If the Inverter Mode is disabled (see elsewhere in this manual) 

this LED will blink. If the LED is lit, the Inverter is in operation and you have 230Vac at output AC OUT. The actual 

power consumption of the AC load is displayed on the power monitor and on the remote display. 

(a) Load detection system “Standby“ 

In order to avoid unnecessary discharge of the battery, the inverter switches OFF automatically if no AC power is being 

used. The Compact switches ON automatically again if an AC load is switched ON. The AC Out LED blinks if the inverter 

is in Standby-Mode. The switching-ON threshold can be adjusted with the “STANDBY” adjustment dial. Adjusting the 

switching-on level is done using a small screwdriver as follows: Switch off all AC loads; turn the “Standby” dial to the right 

until the AC Out is blinking, switch on the smallest AC load (i.e. Mobile phone charger); turn the “Standby” dial slowly to 

the left until the AC Out LED is lit. 

If the Standby- Mode is not wanted, turn the “Standby” dial to the left, to the OFF position, this will keep the Compact 

running continuously, but will also discharge your batteries quicker. 

(b) Overload 

If the Compact is overloaded for too long or too heavily, it switches off. The “Overload“ LED is lit and the “OFF“ LED 

will blink. After approximately 10 seconds the Inverter switches on automatically. If the Inverter is overloaded four times in 

quick succession, then it no longer switches back on automatically, if this occurs contact your Solar Energy Australia representative 

immediately. The OFF LED remains lit. Press the “ON/OFF“ push button in order to switch the Inverter back 

ON. 

(c) Overheating(Over Temp) 

If the Inverter has been overloaded for a long time or it has been working in a high ambient temperature, it will switch OFF. 

The “Over Temp“ LED is lit and the “OFF“ LED blinks. After cooling down, the inverter switches back on automatically. 

One minute before the inverter switches off due to high temperature a buzzer will be heard. If the Auxiliary Contact has 

been programmed for “Over Temp” then the contact will be active when the buzzer sounds. This could be used for example 

to start an emergency back up generator, creating a no break energy supply. 

(d) Battery Condition 

Deep discharging of batteries leads to high losses in capacity and early aging. That is why the Compact will constantly 

monitor the battery condition. When battery voltage gets too low the Compact switches OFF. The “Batt Low/High” LED 

is lit and the “OFF“ LED blinks. When the battery voltage returns to 12.1V / 24.2V / 48.4V, the Inverter switches ON automatically. 

One minute before the Inverter switches OFF due to low voltage, a buzzer will be heard 

If the Auxiliary Contact has been programmed for “Low Battery” then the contact will be active when the buzzer sounds. 

This could be used for example to start a warning system, to shut down critical equipment such as computers. 

The low voltage is set to 11.8V / 23.6V / 47.2V. These settings are standard for most batteries. The voltage levels are maintained 

by the built-in Battery-Management-System of the COMPACT which looks at the load and battery condition and 

adjusts to suit. 

This setting is comparable with the levels of 10.8V/ 21.6V / 43.2, which are given for most batteries on nominal load. 

All voltage levels can be adjusted to suit your system. To adjust these levels see the instructions under the section on Programming. 

Check your battery supplier or system installer for the suggested values for your batteries.

The Battery charger 

(a) Charging Cycle 

The fully automatic COMPACT Battery Charger is adjusted at the factory so that most lead-acid and lead-gel batteries can 

be charged to the maximum. As soon as the minimum AC voltage (as set with the “Transfer” adjustment dial) is available 

at the AC input (“AC IN” LED is lit), the Battery Charger is switched on automatically (“CHARGER” LED is lit). The battery 

is automatically charged to match the pre adjusted voltage levels and charge current. Thanks to the Compacts sophisticated 

and intelligent Floating Charge System, the batteries can be left in charge mode for unlimited time. 

During the charging cycle, the AC loads are continually supplied with power from the incoming AC voltage source. ( “AC 

OUT” LED is lit). 

The charger functions are shown in the following diagram: 

(b) Equalization charging: 

Equalization charge is a higher voltage applied to the batteries for a specified period of time. 

Equalization mode should never be used when using Gel-Batteries 

Before you program the COMPACT for Equalization-charge you must confirm with your supplier that the batteries are suitable 

for this process. 

Equalization is recommended for lead-acid batteries in order to mix the electrolyte fluid and to clean the lead plates of the 

batteries. 

If the COMPACT is operating with a lead-acid battery which is suitable for equalization, the slide switch “Equalize“ which 

is on the cable connection side, must be placed in the ON position. In this setting, at every 25 charge cycles an equalization 

cycle will be carried out for 2 hours (factory setting). During such a charge cycle the “Equalize” LED is lit. During a 

Charge cycle, equalization can be started independent of the actual programming. For this the slide switch must be slid from 

“OFF” to the “ON” position. The Equalize LED will light up. If the periodic equalization is not required, slide switch must 

be slid back to the „OFF“ position after the completion of the manual cycle. 

(c ) Absorption Charge 

Your Compact will provide a constant charge current until the absorption voltage is reached, note that this is the peak voltage 

and may not read accurately with a meter due to the ripple current. LED 15 will flash to indicate the absorption phase 

is running. As the battery state of charge increases, the charge current will be reduced and the battery voltage will continue 

to rise. 

CAUTION: During the equalization process, the batteries will produce a lot more gas.

Input current repartition (Power sharing) 

To manage the power available on the AC INPUT the COMPACT is 

equipped with a system usually called “Power sharing” or INPUT power distribution. 

With this feature it is possible to limit the AC INPUT current assigned 

to the charger. The more current used by the AC load, the less power 

is given to the charger. Priority for the AC Loads. When power sharing is 

used the red 200% LED on the power monitor is lit to show that the battery 

charging is being limited

1500W 6,5A 

2000W 8,5A 

3000W 13A 

Set the INPUT LIMIT 

The current available to the COMPACT depends on the source of the AC input supply, i.e. motor generator, limited grid 

supply in a caravan park or shore power. The value of the “INPUT LIMIT” adjustment dial must be lower or equal to the 

current available from the AC Input source. 

For example if you have a generator of 2kW you must adjust the “Input Limit” to approximately 8.5A. To calculate this, 

divide the nominal power of the AC input source (2000W) by the voltage (230V). If the circuit breaker before the COM- 

PACT is lower than this value, then you must set the “Input Limit” to the value of the circuit breaker. 

Charging current 

The maximum charging current for the battery can be adjusted using the “CHARGER” adjustment dial. The charging current 

should be set to approximately 10% of the battery capacity (at C10). This means that the charging current for a battery 

with 300Ah should be approx 30A. 

The charging current is displayed on the “CURRENT MONITOR” on the front panel and on the Remote Display. 

Battery condition 

The built in microprocessor features a specially developed algorithm 

(formulae) which calculates the actual state of charge ( SOC) of the 

battery and displays it on LED 15-18. The Equalize LED is lit when 

the system is performing an equalization charge. 

The SOC displayed should be used as a guide only, for batteries 

which are not sealed, use a hydrometer to determine the exact SOC. 

For Safety reasons, you must get the recommended charge voltage 

and charge current from your battery supplier. The voltage levels 

and charge characteristics can be changed through “Programming”. 

The correct charging levels are critical for safe functioning and long 

life of the battery.

The Transfer system 

When an AC voltage is present at the AC IN of the COMPACT, the “AC IN” LED is lit. When this voltage matches the 

lowest adjusted value set by the “TRANSFER” dial, and the frequency is between 44Hz and 65Hz, then this power is 

transferred directly to the AC load and the battery charger section of the Compact. The “TRANSFER” LED is lit to indicate 

this has happened. The inverter is then switched off and the battery charger switched on. This process is automatic 

and should not be noticed by the load, at worst a slight flicker may be seen in lights. 

The maximum current of the Transfer switch is 15A. That means through this system, AC loads of up to a maximum 3500 

Watts can be operated. When the Battery Charger is working, part of this power is used for the charging according to the 

power sharing settings. 

The Transfer system is protected against overload with an automatic safety fuse on the AC Input side of the COMPACT. 

If the system has been overloaded the button/pin of the fuse will pop-out. To put the automatic safety system back in to 

operating you must push this pin back in. 


SSC-1601A 

Page 13



Note: In the Inverter operation, the COMPACT generates a True Sineusoidal and quartz stabilized output voltage. 

However, when the COMPACT is transferring power supplied from the a grid or a generator the voltage and quality of the 

power running the AC load will be the same as that coming from the grid or generator. The Compact cannot modify the 

incoming voltage. 

Setting the transfer voltage threshold 

The voltage threshold of the transfer can be adjusted between 150 to 230V with the “Transfer” adjustment dial . This value 

is set at the factory with a value of 200V. The majority of appliances can work on this voltage. When the Input voltages 

reaches the selected value on the adjustment dial, and the frequency is between 44Hz and 65Hz,. then the inverter switches 

off and the AC INPUT goes directly ton the AC OUTPUT. When the voltage INPUT is 20V less than the value set, the 

transfer of power is stopped and the OUTPUT is switched back to the inverter. 

Do not use the adjustment dial “TRANSFER” to adjust the AC OUTPOUT voltage! 

This is only a voltage threshold level to enable or disable the transfer. 

FAST (UPS)- MODE for the Transfer Switch 

The quick and almost break free Transfer mode is programmed with a slide switch „“Transfer Delay“ OFF”, which is on the 

front side with the( cable connections side) of the Compact. 

The aim of the COMPACT is to supply the AC loads with almost break-free AC power. When the incoming voltage “AC 

IN“ no longer matches values which have been set with the “Transfer” adjustment dial, the Compact switches back to 

Inverter. The transfer is carried out in around 0.02 seconds. This quick transfer ensures that the a break-free function for 

most AC loads is achieved. If AC voltage is restored at the AC Input which is within the set parameters, the transfer of 

power will resume, the inverter is stopped and battery charging will recommence. 

Delayed mode of the Transfer System 

The delayed mode of the transfer system Transfer Delay ON is programmed with the slide switch on front with the cable 

connections. The COMPACT provides an almost break-free alternating voltage for the AC loads. A quick transfer switch is 

not always sensible nor is it always desired. For example, when the AC load is being operated by a small standby back-up 

generator. An overload of a short duration on such a generator, i.e. start of a vacuum cleaner etc., has the effect of 

decreasing the voltage for a short time. As in such cases the transfer to the Inverter is not desirable, the transfer system can 

be programmed with a delay. When the slide switch (Transfer delay) is in the „On“ position, the transfer to the inverter 

takes place with a delay of 5 seconds. If the voltage falls below 100Vac, the transfer takes place without delay! The transfer 

switching to the Inverter takes place without any break. 

The Solar charge regulator (option) 

A COMPACT model is available with an inbuilt Solar Charge Regulator. To charge the batteries, Solar modules can be 

connected to the screw terminal SOLAR +/-. The in-built regulator is a Shunt regulator with a maximum input current of 

30A for SSC-12-1k3 and SSC-24-2K3, 20A for SSC-48-3K5. The operating voltage of Solar modules to be connected 

must match the actual operating voltage of the COMPACT and never exceed the max. rated value. 

Under no circumstances should any other charging sources such as a wind-generator be connected at the input of 

the Solar Charge Regulator. 

The Solar Charge Regulator works automatically and is always in operation. As soon as the energy is delivered from the 

Solar Charge Regulator, the “SOLAR CHARGE” LED is lit and the batteries are being charged. The Solar Charge 

Regulator works even when the Battery Charger is functioning. The method of operation is a 3 or 4 step charging process, 

the same as the battery charger. The function is described in the section on “Battery Charging”. The programming and the 

adjustments are carried out in accordance with the same conditions. Check with your battery supplier which adjustments 

must be carried out for your battery.

The Multifunctional Contact 

In the COMPACT there is a built-in programmable power relay. The potential-free change-over contact (n/o – n/c) of this 

power relay is connected to the screw terminals “ AUX CONTACT”. 

Maximum Contact load: 

-230Vac /16Amp-30Vdc/1A 

With the Push Button “AUXILIARY CONTACT“ the contact can be manually switched on or off independent of programming 

and the operating situation. The “Contact active” LED shows the status of the contact. The drawing on the screw terminal 

“AUX CONTACT” shows the inactive position, “Contact active” LED off. 

The switching on and off of this contact can be freely programmed for each operating situation of the COMPACT that is 

indicated with a LED. There is no limitation to its applications. An example and the setting of this contact are explained 

elsewhere in this manual. 

In the factory we program this output to be active when one of these situations are detected: 

* Over temperature LED lit 

* Overload LED lit 

* Over or under voltage of batteries LED lit or blinks 

* Compact is turned OFF manually or with a fault (OFF LED lit) 

* If the COMPACT is turned off manually or has turned OFF due to a fault, the “OFF” LED will be lit. 

THE REMOTE DISPLAY 

As an option, a Remote Display can be connected to the COMPACT. All operating controls and displays except for level 

adjustments are available on the Remote Display. The Remote Control is supplied with a 20m long cable. It can be lengthened 

up to a maximum of 40m. The Remote Display is suitable for surface mounting on the wall or on to a switch board. It 

is fixed with 4 screws. The COMPACT can also be programmed with the Remote Control. The Programming is described 

in the section “Programming“.

PROGRAMMING THE AUXILLIARY CONTACT 

(a) Principle 

The Auxiliary Contact can be basically programmed for any operating situation of the COMPACT which is indicated with a 

LED. The programming is possible for one or more operating situations. If the contact is programmed for many situations, 

it is activated as soon as the COMPACT finds itself in any one of the programmed situations.. 

(b) The programming of the Auxiliary Contact is carried out in the following Steps: 

Press down the “Program” button for min. 2 seconds. The “Program” LED is lit to show the COMPACT is in program 

mode. 

A flashing LED indicates that condition has been programmed to activate the auxiliary contact. The Compact is factory 

programmed with “Over Temp”, “Overload”, “Battery Low High” and “Off” as the conditions which will activate the auxiliary 

contact. These will flash when you first enter the programming mode. 

Once in the programming mode use the “Select” button as per diagram below to choose the desired condition in which the 

contact should be activated, if the yellow “Contact Active” LED is flashing then this condition is already selected to activate 

the auxiliary contact. Pressing the “Change status” button will activate or deactivate this setting. 

If desired , push the “Select” button to choose another condition in which the contact should be activated. 

With the “Change status” button confirm or change the status for this condition. 

If during 10 seconds no buttons are pushed, then the chosen values are automatically stored and the COMPACT switches 

back to normal operating condition

(c) Example 

Auxiliary Contact as generator starter 

When in the programming of the Auxiliary Contact, the State of Charge (SOC)LED’s (LED 15-18) can be used as a condition, 

but you must take note of the following requirements. 

If you have to start an emergency back-up supply with a battery having a certain SOC, then two SOC levels must be programmed. 

The first (i.e. Battery 25% LED 17) for the starting or activating the Auxiliary Contact and the second (i.e. Battery 

100% LED15) for stopping or deactivating the Auxiliary Contact. By programming in this way the Auxiliary Contact 

starts with the lowest set condition and stops when it has reached the highest programmed condition through charging. For 

example if LEDs 15& 17 are programmed to activate the contact, the contact will become activate when only LED 18 is lit. 

The contact will remain activated until LED 15 is lit (after absorption time) 


SSC-1601A

Auxiliary Contact as Twilight Switch (With solar charger option) 

The Auxiliary Contact of the COMPACT can also be used as a twilight switch , i.e. for automatically operating 

exterior lighting. Solar modules connected to the Compact will measure the light intensity. If the COMPACT is 

operating without solar modules and a twilight-switching function is desired, you can connect small solar cells 

with the nominal voltage of the COMPACT to the SOLAR terminals for the purpose of measuring the light 

intensity. To function as a twilight-switch the Auxiliary Contact must be programmed so that the condition 

“SOLAR CHARGE” LED is active. Programming must be carried out in steps and in accordance with the description 

for the programming of the Auxiliary Contact 

Manual operating of Auxiliary Contact: 

The Auxiliary Contact can be operated manually at any time by pressing the “AUX. CONTACT” button. The “Contact 

manual“ LED lights up to indicate that the Contact is manually operated, and the “Contact active“ LED lights up when the 

Contact is active. By pushing the “ AUX CONTACT” button again, the Contact is deactivated. By pushing it a third time, 

automatic functions are restored. 

DISABLING SOME OF THE COMPACT FUNCTIONS 

Each different function, charger, inverter and transfer can be disabled. This is useful for specific applications which are required 

to disable some of these three functions. 

If you press the “Reset Alarm” button for more than 2 seconds you can have access to the different possibilities shown in 

the following diagram. 

In programming mode the display only shows the different types of program with the “Charger”, “Transfer” and “Inverter’ 

functions. To change the type of programming press the “Reset Alarm” button until the LED corresponding to the desired 

function is lit, in to the table below. After 10 seconds the COMPACT will exit the programming mode and function with 

the new programming. In normal user mode, the disabled functions are displayed by a blinking LED
