4. Setup
4.1 Choosing a Location
Select a location for the inverter that is:
- Dry and well-ventilated.
- Away from direct sunlight, heat sources, and flammable materials.
- Secure and stable, preventing accidental movement.
- Accessible for connections and maintenance.
4.2 Connection Guide
IMPORTANT: Ensure the inverter's power switch is in the "OFF" position before making any connections.
- Grounding Connection: Connect a suitable ground wire from the inverter's ground terminal to a reliable earth ground point (e.g., vehicle chassis, building ground). This is crucial for safety.
- Battery Connection:
- Connect the RED battery cable to the RED (+) terminal on the inverter and the positive (+) terminal of your 24V battery bank.
- Connect the BLACK battery cable to the BLACK (-) terminal on the inverter and the negative (-) terminal of your 24V battery bank.
- Ensure all connections are tight and secure. Loose connections can cause overheating and arcing.
- Remote Controller Connection: Plug the RJ45 cable from the ET-RC remote controller into the RJ45 port on the inverter's front panel.
- AC Output Connection:
- For standard appliances, plug them directly into the 4 US AC outlets.
- For high-power appliances (over 1800W, up to 3500W), use the AC Terminal Block. Consult a qualified electrician for proper wiring to the terminal block.
