The unit x 1
User manual x 1
U-terminal x 2

4.2 Preparation
Before connecting all wirings, please take off bottom cover by removing two screws as shown below.
4.3. Mountingthe 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.
Install the unit by screwing two screws. It’s recommended to use M4 or MS screws.
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.
Recommended battery cable size:

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. Connect all battery packs as below chart.
4. 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

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 /OutputConnection
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 1.0KW and 20A for 1.5KW.
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

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)
   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.
   L → LINE (brown or black)
   N → Neutral (blue)

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’ serquired to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers ina 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.
4.6 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.

1.0KW 12V

Every inverter is already installed with anti-dusk kit from factory. Inverter will automatically detect this kit and activate internal thermal sensor to adjust internal temperature. This kit also keeps dusk from your inverter and increases product reliability in harsh environment.
6.2 Clearance and Maintenance(option)
Step 1: Please remove screws as below.

Step 2: Then, dustproof case can be removed and take out air filter foam as shown in below chart.

Step 3: Clean air filter foam and dustproof case. After clearance, re-assemble the dust-kit back to the inverter.
NOTICE: The anti-dust kit should be cleaned from dust every one month.
