INSTALLATION
Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should
have received the following items inside of package:
Inverter unit Software CD Manual Communication cable
Preparation
Before connecting all wirings, please take off bottom cover by removing two screws as shown below.
Mounting the Unit
Consider the following points before selecting where to install:
Do not mount the inverter on flammable construction materials.
Mount on a solid surface
Install this inverter at eye level in order to allow the LCD display to
be read at all times.
The ambient temperature should be between 0°C and 55°C to
ensure optimal operation.
The recommended installation position is to be adhered to the wall
vertically.
Be sure to keep other objects and surfaces as shown in the right
diagram to guarantee sufficient heat dissipation and to have
enough space for removing wires.
SUITABLE FOR MOUNTING ON CONCRETE OR OTHER
NON-COMBUSTIBLE SURFACE ONLY.

Install the unit by screwing three screws. It’s recommended to use M4 or M5 screws.
Battery Connection
CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current
protector or disconnect device between battery and inverter. It may not be required to have a disconnect
device in some applications, however, it’s still required to have over-current protection installed. Please refer to
typical amperage in below table as required fuse or breaker size.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury, please use the

Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the nuts are
tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and ring terminals are tightly screwed to the battery terminals.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.

CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected
tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) must be connected to positive (+) and negative (-) must be connected to negative (-).
AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between
inverter and AC input power source. This will ensure the inverter can be securely disconnected during
maintenance and fully protected from over current of AC input.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. ENSURE that utility AC input is
connected to IN and load AC to OUT and not the wrong way round and also that Line and Neutrals are
connected correctly.
WARNING! All wiring must be performed by a qualified personnel.

Please follow below steps to implement AC input/output connection:
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for eight conductors. And shorten phase L and neutral conductor N 3 mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be
sure to connect PE protective conductor ( ) first.

PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
CAUTION: Please install a surge protection device between inverter and PV modules and the recommended
voltage is 500V.
WARNING! Do switch off the inverter before connecting to PV modules. Otherwise, it will cause inverter
damage.
WARNING! Do NOT connect negative and positive terminal of PV modules to the ground.
WARNING! All wiring must be performed by a qualified personnel.

PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.

Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Check correct polarity of connection cable from PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable to positive
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required
to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a
short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check
manufacturer of air conditioner if it’s equipped with time-delay function before installation. Otherwise, this
inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes
internal damage to the air conditioner.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility
short-circuited when these inverters are worked in parallel operation.
