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:
The unit x 1
User manual x 1
Communication cable x 1
Software CD x 1
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.

Install the unit by screwing three screws. It’s recommended to use M4 or M5 screws.
Battery Connection
CAUTI ON: 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 requested to have a disconnect
device in some applications, however, it’s still requested to have over-current protection installed. Please refer
to typical amperage in below table as required fuse or breaker size.
WARNI NG! All wiring must be performed by a qualified personnel.
WARNI NG! 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
proper recommended cable and terminal size as below.
Recommended battery cable and terminal size:
Model Typical
Amperage Battery Capacity Wire Size Ring Terminal Torque Value

2*4AWG 44 8.4 49.7
Please follow below steps to implement 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
3.2KVA model and at least 200Ah capacity battery for 5.2KVA 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 2-3 Nm. Make sure polarity at both the battery and the solar inverter is correctly
connected and ring terminals are tightly screwed to the battery terminals.

WARNI NG: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTI ON!! Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTI ON!! Do not apply anti-oxidant substance on the terminals before terminals are
connected tightly.
CAUTI ON!! 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 I nput/ Output Connection
CAUTI ON!! 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 30A
for 3.2KVA, 50A for 5.2KVA.
CAUTI ON!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input
and output connectors.
WARNI NG! All wiring must be performed by a qualified personnel.
WARNI NG! 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 proper recommended cable size as below.
Suggested cable requirement for AC wires
Model Gauge Torque Value
3.2KVA 10 AWG 1.2~ 1.6 Nm
5.2KVA 8 AWG 1.4~ 1.6Nm
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 six 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.

WARNI NG:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
4. Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.
Be sure to connect PE protective conductor ( ) first.
→Ground (yellow-green)
L→LI NE (brown or black)

5. Make sure the wires are securely connected.
PV Connection
CAUTI ON: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
WARNI NG! All wiring must be performed by a qualified personnel.
WARNI NG! It'’ very important for system safety and efficient operation to use appropriate cable for PV module
connection. To reduce risk of injury, please use the proper recommended cable size as below.
Model Typical Amperage Cable Size Torque
3.2KVA with MPPT 60A 6 AWG 1.2~1.6 Nm
5.2KVA with MPPT 80A
CAUTI ON: I mportant
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.
CAUTI ON: 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
solar inverter will trig overload fault and cut off output to protect your appliance but sometimes it still causes
internal damage to the air conditioner.

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.
Solar Charging Mode (MPPT type)
I NVERTER MODEL 3.2KVA 5.2KVA
Max. PV Array Open Circuit Voltage 145Vdc
PV Array MPPT Voltage Range 30~115Vdc 60~115Vdc
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

pole (+) of PV input connector. Connect negative pole (-) of connection
cable to negative pole (-) of PV input connector.
3. Make sure the wires are securely connected.
Final Assembly
After connecting all wirings, please put bottom cover back by screwing two screws as shown below.
Communication Connection
Please use supplied communication cable to connect to inverter and PC. Insert bundled CD into a computer and
follow on-screen instruction to install the monitoring software. For the detailed software operation, please
check user manual of software inside of CD.
