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. 200 mm to the side and approx. 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 to keep other objects and surfaces as shown in the

below 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.

Install the unit by screwing two screws.

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 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 and terminal size as below.

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.

2. 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 inverter/charge is correctly

connected and ring terminals are tightly screwed to the battery terminals.

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 anti-oxidant substance on the terminals before terminals are

connected tightly.

CAUTION!! Before making the final 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 10A

for 1kW, 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 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.

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.

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 qualified personnel.
