2.0 Installation
Environment
• The inverter (or combi) must be placed in a dry, well ventilated and dust free location.
• Place the unit as close as possible to the battery in order to keep the battery cables as short as possible.
• Do not place the unit in same compartment as the batteries.
• Make sure that water or dust can not enter the cabinet.
• Ensure that the air flow from fan is not obstructed.
• Avoid mounting the device next to flammable materials.
Mounting the device
• The unit can be mounted on a wall, or flat mounted (4 x Ø5mm holes)
• Optimum cooling is obtained in vertical position.
• Make sure that each wire used in the installation has at least the same intersection and correct length, as
given in this manual!
• During wiring, use standard cable fixtures and wire ducts, do not bent extremely the cables/wires, and
avoid sharp edges to prevent the isolation of the wires/cables from cutting and abrasion.
• Keep in mind that usage of too long battery cables and dirty or loose connections may produce a
significant voltage drop which would cause that the device shut down for under voltage, even if the
battery is ok!
2.1 DC cables
EMC
• The wiring of the cables is influencing the EMC behavior of the system, in which the inverter is a
component. This is due to the fact that the cables are receiver and transmitter antennas of radio frequency
electromagnetic interference.
• Good EMC properties are obtained in the following way: Place the cables in a metal rail. The metal offers
resistance against interference currents. The battery cables should be placed close to each other to reduce
looping area. Cables from different groups should not be twisted, but be placed parallel with each other.
Recommended cable
• The table bellow is given by a criterion to keep the total cable voltage drop lower than 250mV at max
nominal power delivered by the combi.
Note: When starting up heavy load with high inrush current (compressors, motors, etc) it is
recommended to use cables with a even higher intersection (or shorter length) to prevent under-voltage
shut-down of the device
.
• The cable length (up to 3 meter) between the battery and the combi must be sized according to the table
below:
Note: Avoid cables longer than 3 meters between battery and combi!
Note: Cable length are defined per each cable (or as the distance between battery and combi)

Mounting DC cables
• PAY ATTENTION TO CORRECT POLARITY!
• Check that the battery voltage matches the DC input to the inverter (or combi).
• Check the battery poles are clean.
• Prepare good electrical contact, use brass or lead battery connectors at the battery poles.
• Connect only one cable at the time.
• Start with the Black cable (-). First connect to battery pole, then to inverter (or combi) (-) terminal
(black)
• Double check that Black (-) cable are connected to the correct terminals (-)
• Secure there is no risk of short circuit!
• Connect Red cable (+). First to battery pole, then to inverter (or combi) (+) terminal (red)
• When connecting the cables a spark will occur. Avoid sparks near the battery!
WARNING!
• Do not interchange the battery cables. It will result in instantaneous damage of the unit. Such
damage is not covered by the guarantee.
• Do not connect inverters (or combi) in parallel. It will damage the unit (s). Such damage is not
covered by the guarantee.
• Do not connect AC generator or AC mains to the unit’s AC output connector (grey Neutrik). It will
damage the unit. Such damage will not be covered by the guarantee.
2.2 AC Mains cables
• When installing the AC cables always refer to safety standards valid in your country!
• The use of RCD devices – also known as FI fail current protection is highly recommended in any
installation!
Recommended AC cable
• The table bellow gives the minimum recommended wire sizes of the mains cables!
• AWG 15 = 1.5mm2 AWG 17 = 1.0mm2
• The assembly of the mains connector is described in section 3.3 Neutrik connector’s assembly

5.0 Operating the device
•The aim of this section is to give a brief overview necessary to operate the device and give some proposal
how to solve most normal problems occurring during operation of the device.
Information for all LED error codes can be found in section 6.0 LED Code description.
Combi devices can operate in 3 modes:
Inverter mode
• Energy is taken from the battery, inverted to 230VAC delivered at output connector (grey Neutrik).
Charger mode
• The charger switch on automatically when a public grid or an AC generator (185-
265VAC) is present at the
AC input connector (blue Neutrik), a relay bypass the supplied AC voltage to the output (grey Neutrik). At the
same time some of the energy (from grid or generator) goes to recharge the battery bank.
Back up mode
• In case of black out of AC public grid, the device will switch over automatically to inverter function and the
connected equipment will still run powered by the battery.
• Important: the inverter section must be switched on!
Inverter section:
Switch ON the inverter
• Push down ON/OFF power switch for approximately. 2 seconds both blue and red LED will light.
• After 2 seconds red LED stops and the power switch can be released.

c. AC input connector , type Neutrik NAC3FCA ( Blue )

Charger section:
Charge current adjust
• The charge current can be adjusted by the potentiometer on the front panel top from 0A
up to maximum
rated charge current.
• See recommended charge current table in section 5.2 Charge Current Setting for correct adjustment.
Charge characteristic setup
• Future option!
Activate the charger
• The charger section will automatically switch on regardless of the ON/OFF power switch status, when 185-
265VAC is connected to the AC input (blue Neutrik)
Note: If the inverter is switched OFF, the charger will operate at even lower voltage than 185VAC,
down to
110VAC is in this mode is accepted But with reduced charge current!
Note: If AC was connected and then removed (short charge time), the inverter can be restarted even if the
battery is still empty!
Charge power reduction
• 2300W (10A) from the AC grid should not be exceeded! The charger reduces automatically the charge
current if the total power exceeds 2300W (charge power + load power)
Note: the regulation is slow in order to allow load peak currents, without disturbing the charging!
Important: The device has a build in fuse – see FUSING section -, do not exceed this limit!
Boost charging
• Fast flashing green LED, the charger delivers full charge current to the battery
Top charging
• Slow flashing green LED, the charge current is reduced in order not to exceed max battery voltage
allowed.
Fully charged battery
• Continuously light green LED
Deactivate the charger
• Remove AC, charging will stop.
Note: If the inverter was activated (ON) there will be 230VAC at the grey output connector (discharging)

Errors charger:
AC input voltage to low <185VAC (with inverter switched ON)
• 1 flash by green LED
Note: If the inverter is switched OFF, the charger will operate at even lower voltage than 185VAC,
down to
110VAC is in this mode is accepted But with reduced charge current!
AC input voltage to high >265VAC
• 2 flash by green LED (rear situation!)
AC input distortion
• The charger can not begin charging if the input voltage is a non sine wave, or heavily distorted!
• 1 flash by green LED
No NTC temperature sensor connected
• 4 flash by green + red LED together
Note: “No NTC connected” status is indicated every time the charger is connected to AC voltage (110VAC-
265VAC)
Note: “No NTC connected” flash code is only present for 20 seconds, and then the green LED will indicate
the actual charge status.
Note: If no NTC is used, the charger will charge the battery without temperature compensation!
Poor connections (or disconnection of battery during charging)
• 2 flash all LED together
Note: Always make sure that all connections joints are in a good quality: tighten all screws, wiring size must
be correct dimensioned, no corrosion at terminals etc.
WARNING!
Never disconnect cables during charging (and inverting) especially near the battery bank.
The battery can explode!
Defect battery
• The battery must be able to deliver min. 12W and min. 10,3V before charging can start!
Note: Never discharge a battery completely; it will cause permanent damage of the battery!
• No LED code for this error

5.1 Load search mode
• In cases where it is preferable to leave the combi switched on, and the load is periodically inactive
(switched OFF) the load search mode can be activated.
In this mode the combi is partly active and generate a short pulse every 2 second, if a load (>10W resistive)
is detected the device switch ON automatically. When a load is disconnected again the device automatically
returns to search mode (low consumption) after 1 min without load
• In load search mode the battery consumption is reduced to less than 3
W in order to save the battery during
no load periods!
Activate load search mode
• Switch OFF if the combi (if activated)
• Push down the power switch for > 5 seconds
• Release only when the blue, green and red LED starts to light at the same time.
Note: in load search mode the battery consumption is reduced, while no load is active! The device switch on
automatically when a load is connected (> 10W resistive)
The load search mode will remain active, until deactivation or disconnection of the battery (the mode will be
active > 15min after disconnecting the battery)
Note: there will be a small delay when connecting a load and until the device starts up automatically!
Note: If load search mode is entered with a load connected, the blue LED flashes slowly only
for 5 seconds
(to indicate entering of load search mode), then it lights continually!
Note: When a load has been connected and afterwards disconnected the device stays fully ON for 1 min
then it returns again to search mode (low battery consumption).
Deactivate load search mode
• Push power switch > 5 seconds.
• Release only when Blue, green and red LED start to flash at the same time.
Remote used with load search function
• The load search function will remain active if the device is switched ON and OFF by remote.
• Only deactivation (or disconnection of battery >15 min) will clear load search mode

ATTENTION!
• If sealed lead acid batteries are overcharged it will result in gassing and dry-out and the battery will
be destroyed.
• Wet batteries (open type) will loose water and need to be topping up.
• If you are in doubt how your battery / batteries shall be charged please consult your Battery
Technical Manual (data sheet), or your local battery distributor.
Temperature compensation (NTC sensor)
• When using the external temperature sensor (NTC) the charger will reduce the charge current with respect
the max allowed battery voltage at the actual temperature!
• Refer to scheme: at 20°C the boost charge max voltage is 14,4V and float charge voltage 13,5V
• Use the NTC temperature sensor for optimal battery performance.

5.3 Charging Stages
• The charger is a fully automatic 3-stage charger with IUoUo characteristic.
Boost charge - Fast flashing green LED
• The charger will start in boost charge mode with max pre-set voltage and max charging current.
Top charging - Slow flashing green LED
• The battery has reached the maximum pre-set charging voltage and will automatically reduce the
charge
current until the charger measure 1Amp
Battery Full (Float charge) - Continuously light green LED
• The battery was detected fully charged.
Maintenance current (Float charge) - Continuously light green LED
• The charger keeps a pre-set float charge voltage, and adjusts the charge current automatically
to
compensate for battery discharging.
• The charger can deliver up to 50% (of max adjusted charger current) at float charge voltage.
• If the battery voltage drops below float charge voltage level, the charger switch over to boost charge mode.
