4. Setup and Installation
4.1 Mounting
Mount the inverter vertically on a sturdy, non-flammable surface. Ensure there is sufficient clearance around the unit for proper airflow and heat dissipation. Avoid direct sunlight and heat sources.
4.2 Wiring Connections
All wiring must comply with local electrical codes and standards. Use appropriately sized cables for all connections.
- Grounding Terminal: Connect the inverter to an earth ground using a suitable grounding wire.
- Battery Connections (48V DC): Connect the positive and negative terminals of your 48V battery bank to the corresponding battery positive and negative terminals on the inverter. Ensure correct polarity.
- Solar Panel Input: Connect your solar array to the MPPT solar input terminals. Observe correct polarity and ensure the PV open circuit voltage does not exceed 160VDC.
- AC Input (Utility/Generator): Connect the AC utility grid or a generator to the AC input terminals. This allows for battery charging and load powering from an external AC source.
- AC Output (Loads): Connect your AC loads (e.g., ovens, refrigerators, washing machines) to the AC output terminals. The inverter provides 110/240V AC output, settable via the LCD screen.
