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 the package:
The unit Mounting plate Fixing screws RS-232 cable USB cable Software CD
User manual Current sharing cable Parallel communication cable
Preparation
Before connecting all wirings, please take off the cover of the bottom by removing the six screws as shown
below.
Mounting the Unit
Consider the following points before selecting where to install:
⚫Do not mount the inverter on any flammable construction materials.
⚫Mount this inverter on a solid surface
⚫Install this inverter at eye level in order to read the LCD display at all
times.
⚫The ambient temperature should be between 0°C and 55°C to
ensure optimal operation.
⚫The inverter should be adhered to the wall vertically.
⚫Be sure to keep other objects away and leave the space in a
minimum as shown in the right diagram to guarantee sufficient heat
dissipation and enough space for replacing wires.
SUITABLE FOR MOUNTING ON CONCRETE OR OTHER
NON-COMBUSTIBLE SURFACE ONLY.

5
Install the unit by screwing four screws as shown in the diagram.
It’s recommended to use M5 screws.
1. Drill four holes in the marked locations with 4
screws. The reference tightening torque is 35
N.m.
2. Raise the inverter and place it over the mounting
plate.
Battery Connection
CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current
protector or disconnect the device between battery and inverter. It may not be necessary to disconnect the
device for some applications, however, it’s requested to have over-current protection installed. Please refer to
the typical amperage in the table below as required fuse or size of the breaker.
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 proper
cables and suitable size of terminal recommended below.

Please follow the steps below to implement the battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. Connect all battery packs as units requires. It’s suggested to connect at least 200Ah capacity battery for
5KW model.
3. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts
are tightened with torque of 5-6 Nm. Make sure polarity at both the battery and the inverter is correctly

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 any anti-oxidant substance on the terminals before the 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. The recommended spec of AC breaker is 40A.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input
and output connectors.
WARNING! All wiring must be performed by the qualified personnel.
WARNING! It’s necessary to connect AC input N wire. Otherwise, the inverter will NOT be able to detect
AC input.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC
input connection. To reduce risk of injury, please use the recommended cable size as below.
