4.2 Preparation
Before connecting all wirings, please take off bottom cover by removing two screws as shown below.
4.3 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.
 For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and approx. 50
cm 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 to keep other objects and surfaces as shown in the 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.

4.4 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 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.
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 proper recommended cable as below.
If the customer chooses the external battery.
Recommended battery cable size:
Model Wire Size Cable (mm
2
) Torque value（max）
3.2KW/5KW 1 x 2AWG 35 2 Nm
Please follow below steps to implement battery connection:
1. Remove insulation sleeve 18 mm for positive and negative conductors.
2. Suggest to put bootlace ferrules on the end of positive and negative wires
with a proper crimping tool.
3. Fix strain relief plate to the inverter by supplied screws as shown in below
chart.
4. Connect all battery packs as below chart.
5. .Insert the battery wire flat into the DC breaker input side to ensure that the bolt is tightened 2nm clockwise.
Ensure that the polarity between the battery and the inverter / charging is connected correctly, and the wire is
tightly screwed into the DC breaker terminal.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
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
(-).

4.5 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 32A for
3.2KVA and 50A for 5KVA.
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 a qualified personnel.
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 proper recommended cable size as below.
Suggested cable requirement for AC wires
Model Gauge Cable (mm2) Torque Value
3.2KW 12 AWG 4 1.2 Nm
5KW 10 AWG 6 1.2 Nm
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.
→Ground (yellow-green)

4.7 Final Assembly
After connecting all wirings, please put bottom cover back by screwing two screws as shown below.
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.
