How to Use

The inverter charger must be installed and configured according to its user manual. Electrical installation, wiring, and grounding should be completed by qualified personnel.

Step 1: Choose an Appropriate Installation Location

Install the inverter in a dry, clean, cool, and well-ventilated location.

Maintain at least 30CM (11.81 inches) of clearance around the unit to allow proper airflow.

Do not obstruct ventilation openings or install the inverter near flammable materials.

Step 2: Complete the DC Battery Connections

Follow the manufacturer's DC wiring instructions for the 12V battery system.

The manual recommends keeping the battery bank as close as practical to the inverter and using properly sized cables.

Step 3: Complete the AC Wiring and Grounding

Follow the manual's AC wiring and grounding requirements.

The inverter's AC output must never be connected directly to utility power or generator output.

Step 4: Select the Battery Charging Configuration

Use the battery-type selector to choose the appropriate charging setting for the connected battery.

The charging function can be disabled using the designated charger-off setting.

Step 5: Configure AC or Battery Priority

The inverter uses AC priority by default.

Use the SW5 switch to select battery priority when required.

Step 6: Select the Output Frequency

Use the SW4 switch to select the required 50Hz or 60Hz output frequency.

Step 7: Adjust the Charging Current

Use the charging-current adjustment control to configure the charging current according to the connected battery's requirements.

Step 8: Monitor Operating Conditions

Use the LCD display and indicator lights to monitor the inverter's operation.

The indicators identify conditions including:

• Shore power operation

• Inverter operation

• Fast charging

• Float charging

• Power-saving mode

• Overtemperature protection

• Overload protection

Important Safety Precautions

• Disconnect both AC and DC power before cleaning or performing maintenance.

• Do not expose the inverter to rain, snow, spray, or excessive dust.

• Do not obstruct the ventilation openings.

• Do not operate the inverter with damaged or undersized wiring.

• Do not install the inverter in compartments containing batteries or flammable materials.

• Do not attempt to disassemble or repair the inverter yourself.

• Never connect the inverter's AC output directly to its AC input, utility power, or a generator output.

• Do not use the inverter to power life-support systems or other medical equipment.
