Caution: Even when an HP COMPACT has been completely disconnected, there can still be deadly voltages pre-
sent at the OUTPUT. To remove these voltages you must switch the COMPACT ON with the ON/OFF switch. Af-
ter 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 batter-
ies.
The HP 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 rec-
ommended 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. Batter-
ies 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 HP 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 HP COMPACT generates a sinewave AC voltage with an exceptionally precise volt-
age 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 HP COMPACT.
The inverter is protected against overload and short-circuit. A power-stage with the latest MOS-FET power transistors, a
torroidal 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
HP COMPACT can be connected to an AC input source, eg. a stand-by motor generator, AC grid, 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 batter-
ies 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 – 100%. 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 HP 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 display (optional)
A remote display can be connected to your HP COMPACT. All operating elements and displays with the exception of the
load detection level adjustment are available on the remote display. The remote display is supplied with a 20m long cable.
This cable can be up to 40m long. On the remote display 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 HP COMPACT many batteries have to be connected together in parallel and
or in series. Three examples are shown:
12V 12V 12V

INSTALLATION
Location
The location of the HP COMPACT must be chosen by the following criteria:
•Protection from unauthorized access and children.
•Dry dust free room, no condensation, no rodents. Power sheds MUST have 4 walls and a lockable door
•Never install directly over the battery and never in a cabinet together with the batteries.
•Keep ventilation holes free. The ventilation of the HP COMPACT is designed in such a way that it will work most
efficiently when mounted vertically.
•In mobile installations it is important to keep vibrations to a minimum.
Mounting
1. HP Compact
The HP COMPACT can be installed in any desired location but only vertically. Screw the fixing bracket to the wall, and
hang the HP Compact onto this bracket, insert two screws at the bottom of the unit. In motor vehicles, the HP COMPACT
must be fixed on vibration reducing mounts. The HP 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.
All connecting cables and also the mounted battery cables , must be fixed with strain relief clamps.
The battery cables must be as short as possible,. your installer will calculate the appropriate size cables.
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 installa-
tions, maintenance must be carried out more often.
Connections
1. General instructions on connecting
All connections for the HP Compact are done by removing the cover plate above the cable glands.
The cable connection on the terminals AC INPUT / AC OUTPUT must be carried out with a No 3 screwdriver, the con-
nection on the AUX RELAY terminal must use a No 2 screwdriver.

Cabling/wiring
When making connections to the HP 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 HP COMPACT must be carried out in the following order.
(a) Pre-installation settings
Before you start with the wiring of the HP 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 batter-
ies, these can handle a higher equalizing charge, the same slide switch can be set to the ON position. This will allow an equalizing cycle
(higher end of charge voltage) during the next charge cycle, after that equalizing will occur every 25 normal cycles.
If in doubt leave the setting in the OFF position.

Battery Connections at the Inverter
Attach the supplied cable glands to the DC cables before attaching any lugs to the other end of the cable. Con-
nect the red cable (+) to the Inverter in accordance with the diagram below.
Connect the black cable (-) to the Inverter in accordance with the diagram below. The fuse is supplied stan-
dard with all HP Compact models with the exception of SSC-12-2k5
Bolt M8 x 30
Ceramic washer
Fuse cartridge CF8
(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
2,5mm2. Connections are marked as follows “N“= Neutral, “PE“= Earth, “L“= Live or Active.

OPERATING
FINAL CHECK ALL WIRING AND CONFIRM CORRECT BATTERY VOLTAGE AND POLARITY
Caution: With a wrong battery voltage the COMPACT can be destroyed. ( For example: connecting a SSC-12-2K5 to a 48V Bat-
tery).
If the COMPACT has been connected with reverse battery polarity, it must be returned to Solar Energy Australia for repair.
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.
(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.
Connections are marked as follows “N“ =Neutral, “PE“= Earth, “L“ = Live/Active.
(e) 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 on the PCB of
the HP Compact, shows the contacts in the non active state.
(f) 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 Display
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, it comes
standard with 20m cable.
(g) 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 Tem-
perature 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.

The Inverter
The Inverter section of the HP 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 HP COMPACT for a short time. The HP COMPACT provide up to 3-times the nomi-
nal power to start motors etc.
The Inverter mode is displayed by the LED marked “Inverter” If the Inverter Mode is disabled (see elsewhere in this man-
ual) 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 HP 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. Adjust-
ing 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 HP Compact
running continuously, but will also discharge your batteries quicker.
(b) Overload
If the HP 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 repre-
sentative 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 HP Compact will constantly
monitor the battery condition. When battery voltage gets too low the HP 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 main-
tained by the built-in Battery-Management-System of the HP 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 Pro-
gramming. Check your battery supplier or system installer for the suggested values for your batteries.

The Battery charger
(a) Charging Cycle
The fully automatic HP 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 avail-
able 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 HP 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 HP 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 HP 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, every 25 charge cycles an equali-
zation 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 volt-
age 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

Input current repartition (Power sharing)
To manage the power available on the AC INPUT, the HP COMPACT is
equipped with a system usually called “Power sharing” or INPUT power dis-
tribution. With this feature it is possible to limit the AC INPUT current as-
signed 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

2000W 8,5A
3000W 13A
Set the INPUT LIMIT
The current available to the HP 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 HP
COMPACT 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 cur-
rent should be set to approximately 10% of the battery capacity (at C10). This means that the charging current for a battery
with 300Ah (C10 rate) 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 HP 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 HP 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 auto-
matic 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 HP COM-
PACT. 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.

Note: In the Inverter operation, the HP COMPACT generates a True Sineusoidal and quartz stabilized output voltage.
However, when the HP 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 HP 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 HP Compact.
The aim of the HP 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 HP 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 HP 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 Multifunctional Contact
In the HP 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 program-
ming and the operating situation. The “Contact active” LED shows the status of the contact. The drawing on the screw ter-
minal “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.
As an option, a Remote Display can be connected to the HP COMPACT. All operating controls and displays except for
level adjustments are available on the Remote Display. The Remote Display 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 HP COMPACT can also be programmed using the Remote Display. The Programming
is described in the section “Programming“.

Programming Voltages and timing threshold.
When programming your HP Compact, switches and LED’s perform different functions as they do when in the normal
mode, the diagrams below shows the function of each when in the programming mode, the normal meanings are in brack-
ets. Programming can be done at any time and will not interfere with the HP Compacts operation. All voltages mentioned
should be halved for 12v systems and doubled for 48v systems.
All voltage and Timing programming is done in the following manner:
Press “Program” & “Change Status” buttons simultaneously to enter programming mode
Press the “Select” button to choose the parameter you want to change
Press “Change Status” button to change the values.
If no buttons are pressed for 10 seconds whilst in the programming mode, the display will revert back to normal operation.
The voltage levels and times changed through programming will be active with the next charge cycle! Any changes
made to voltage levels will be lost if the Inverter is disconnected from the battery.
CAUTION Voltage levels which are not suitable can greatly reduce the battery life or could even destroy it ! Check
with your battery supplier if unsure.
