4. Setup and Installation

Before installation, ensure all components are present and undamaged. Refer to the wiring diagram for correct connections.

1. Mounting: Choose a suitable location for mounting the inverter. Ensure it is a dry, well-ventilated area, away from direct sunlight and flammable materials.
2. Battery Connection: Connect the battery bank (24V DC) to the inverter's battery terminals. Ensure correct polarity (positive to positive, negative to negative).
3. Solar Panel Connection: Connect the solar panel array to the PV input terminals. Ensure the PV array's voltage and current are within the inverter's specifications (MPPT voltage range: 220V/230V DC).
4. AC Input Connection (Optional): If using grid power or a generator, connect the AC input to the designated terminals. Note: Do not connect utility and generator to the AC input simultaneously.
5. AC Output Connection: Connect your AC loads (appliances) to the inverter's AC output terminals.
6. Grounding: Connect the inverter's grounding terminal to a reliable earth ground.
7. Initial Power-Up: After all connections are secure, switch on the battery breaker first, then the inverter's power switch.
