should have received the following items inside of package:
The unit x 1
User manual x 1
Communication cable x 1
USB 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 ammable construction
materials.
Mount on a solid surface 300mm
Install this inverter at eye level in order to allow the
LCD display to be read at all times.
For proper air circulation to dissipate heat, allow a
clearance of approx. 200 mm to the side and approx. 200mm
300 mm above and below the unit.
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 keep other objects and surfaces as shown
in the below diagram to guarantee sufcient heat
300mm
dissipation and to have enough space for removing
wires.

Battery Connection
CAUTION: To 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 beaker size.

WARNING! All wiring must be performed by a qualied personnel. 18

WARNING! It's very important for system safety and efcient operation
18
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
100AH 1*6AWG
2KW 66A
200AH 2*10AWG
100AH 1*4AWG
3KW 100A
200AH 2*8AWG
Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. 1KW model supports 12VDC system. Connect all battery packs as below chart, It’s suggested
to connect at least 100Ah capacity battery for 1KW model. 2KW/3KW model supports 24VDC
system. Connect all battery packs as below chart, It’s suggested to connect at least 100Ah
capacity battery for 2KW-3KW model.

WARNING: Shock Hazard

Installation must be performed with care due to high battery voltage in series.

CAUTION!! Do not place anything between the at 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 nal DC connection or closing DC breaker/disconnector,
be sure DC (+) must be connected to DC (+) and DC (-) must be connected to DC (-).

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 20A for 2KW, 32A for 3KW.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT-misconnect
Input and output connectors.
WARNING! All wiring must be performed by a qualied personnel.
WARNING! It's very important for system safety and efcient 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
2KW 14AWG 0.8~1.0Nm
3KW 12AWG 1.2~1.6Nm

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 rst.
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 ( )rst.

 →Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)

WARNING:
Be sure to 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 ( )rst.
→Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)

5. Make sure the wires are securely connected.

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 working in parallel operation.

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.

PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between
inverter and PV modules.
WARNING! All wiring must be performed by a qualied personnel.
WARNING! It's very important for system safety and efcient operation to use appropriate cable
for PV module connection. To reduce risk of injury, please use the proper recommended cable size
as below.
