How to Use

Important: This inverter charger contains hazardous AC and DC voltages. Installation and electrical connections must be performed by qualified personnel in accordance with the applicable model-specific user manual and local electrical codes.

Step 1: Select the Installation Location

Choose a suitable mounting surface with adequate ventilation and sufficient clearance for heat dissipation.

Avoid damp, dusty, oily, flammable, explosive, or excessively hot environments.

Do not install the inverter and lead-acid batteries together in a confined space where battery gases may accumulate.

Step 2: Remove the Terminal Cover

Before making any electrical connections, disconnect the relevant external breakers or fuses.

Remove the inverter's terminal protective cover according to the installation manual.

Step 3: Complete the Electrical Connections

A qualified installer must connect the equipment according to the wiring diagram for the selected inverter model.

The manual identifies the following connections:

1. AC input wiring

2. AC output wiring

3. Photovoltaic input wiring

4. Battery wiring

5. Protective grounding

For AC input and output connections, the manual specifies connecting the ground conductor before the live and neutral conductors.

Verify that the battery and photovoltaic positive and negative terminals are correctly connected.

Do not energize the circuits while electrical connections are being made.

Step 4: Inspect All Connections

Before startup:

1. Check that the AC input wiring is correct.

2. Confirm the AC output connections.

3. Verify battery polarity.

4. Verify photovoltaic input polarity.

5. Confirm that the wiring terminals are secure.

6. Check the required grounding and circuit protection.

Step 5: Reinstall the Terminal Cover

Once all wiring has been inspected and confirmed, reinstall the terminal protective cover.

Step 6: Power On the Inverter

Follow the startup sequence specified in the manual:

1. Close the battery terminal circuit breaker.

2. Move the inverter's rocker switch to ON.

3. Check the AC/INV indicator for normal inverter operation.

4. Close the photovoltaic array and AC input breakers.

5. Confirm that the AC output is operating normally.

6. Turn on connected AC loads one at a time.

For multiple loads, the manual recommends starting the load with the larger surge current first. After that load stabilizes, turn on the smaller-surge loads.

Step 7: Configure the Operating Mode

Use the LCD control panel to select the appropriate charging and output settings for the installation.

Available charging modes include:

• AC Priority

• Solar Priority

• Only Solar

• Mains & Solar Hybrid Charging

Confirm that the battery charging settings are compatible with the connected battery manufacturer's requirements.

Step 8: Monitor System Operation

Use the LCD and LED indicators to review available information, including:

• Battery voltage and charge level

• PV input voltage

• Charging current and power

• AC input and output information

• Load conditions

• Inverter operating status

• Alarm and fault codes

Use the UP and DOWN buttons to scroll through the available real-time information.

If a fault occurs, follow the troubleshooting instructions in the appropriate model's user manual.
