4.3 Wiring Connections
CAUTION: Before making any connections, ensure the inverter is switched OFF and the battery bank is disconnected or fused.
- Grounding: Connect the ground terminal of the inverter to an earth ground point using the provided ground cable. This is crucial for safety.
- DC Input Connection:
- Connect the positive (+) terminal of your 12V DC battery bank to the positive (+) DC input terminal on the inverter.
- Connect the negative (-) terminal of your 12V DC battery bank to the negative (-) DC input terminal on the inverter.
- Use appropriate cable gauge for the DC input to minimize voltage drop and ensure safe operation.
- AC Output Connection:
- Connect your AC loads (appliances) to the AC output terminals of the inverter.
- Ensure the total power consumption of your AC loads does not exceed the inverter's continuous power rating (3000W).
- Optional Connections (RS485 & USB):
- If using the RS485 communication feature, connect the RS485 cable to the designated port for remote monitoring.
- The USB port can be used to charge compatible 5VDC devices.
5. Operating Instructions
5.1 Powering On the Inverter
- After all connections are securely made and verified, connect the battery bank (if not already connected).
- Switch on the DC input breaker or fuse, if installed.
- Press the power button on the inverter. The LCD display will illuminate, indicating the inverter is operational.
- The inverter will begin converting DC power to AC power.
5.2 Powering Off the Inverter
- Turn off all connected AC loads.
- Press and hold the power button on the inverter until the display turns off.
