wall vertically.
lBe 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.

6
Install the unit by screwing two 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 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.
Recommended battery cable size:
Model Wire Size Cable (mm2)Torque value（max）
1KVA/2KVA 1 x 4AWG 25 2 Nm
3KVA/5KVA 1 x 2AWG 35
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.

7
4. 1KVA model supports 12VDC system, 2KVA/3KVA model supports 24VDC system and 5KVA model supports
48VDC system. Connect all battery packs as below chart. It’s suggested to connect at least 100Ah capacity
battery for 1-3KVA model and at least 200Ah capacity battery for 5KVA model.
5. Insert the battery wires flatly into battery connectors of inverter and make sure the bolts are tightened with
torque of 2 Nm in clockwise direction. Make sure polarity at both the battery and the inverter/charge is
correctly connected and conductors are tightly screwed into the battery terminals.
Recommended tool: #2 Pozi Screwdriver
6. To firmly secure wire connection, you may fix the wires to strain relief with cable tie.
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
(-).

8
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 10A
for 1KVA, 20A for 2KVA, 32A for 3KVA 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
1KVA 16 AWG 1.5 0.6 Nm
2KVA 14 AWG 2.5 1.0 Nm
3KVA 12 AWG 41.2 Nm
5KVA 10 AWG 61.2 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. For 1KVA/2KVA model, simply connect AC utility to AC input of the inverter with a plug.
For 3KVA/5KVA model, 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)
L→LINE (brown or black)
N→Neutral (blue)
WARNING:
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.

1KVA/2KVA 3KVA/5KVA
5. Make sure the wires are securely connected.
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.

10
PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
WARNING! It's 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.
