4. Setup and Installation
4.1 Choosing an Installation Location:
- Select a cool, dry, and well-ventilated area.
- Avoid direct sunlight, heat sources, and moisture.
- Ensure sufficient clearance around the inverter for proper airflow, especially around the cooling fan.
- Mount the inverter securely on a stable surface.
4.2 DC Input Wiring:
WARNING: Before making any connections, ensure the inverter's power switch is OFF and disconnect the positive terminal of your battery bank.
- Connect the supplied red battery cable to the positive (+) DC input terminal on the rear of the inverter. Tighten securely.
- Connect the supplied black battery cable to the negative (-) DC input terminal on the rear of the inverter. Tighten securely.
- Connect the other end of the red cable to the positive (+) terminal of your 48V battery bank.
- Connect the other end of the black cable to the negative (-) terminal of your 48V battery bank.
- Ensure all connections are tight and secure to prevent loose connections, which can cause overheating and damage.
4.3 AC Output Wiring (High Current Terminals):
The inverter features high current AC output terminals in addition to standard US sockets. These terminals are designed for stronger current handling. The image below illustrates these connections.
Image: Close-up of the high current AC output terminals on the Xijia inverter, showing labels for 'L' (livewire), 'N' (neutralwire), and a grounding symbol. Note: The image also contains a warning 'All have voltage !!!' under 'livewire neutralwire'.
IMPORTANT GROUNDING NOTE: The image indicates a grounding terminal. However, user feedback suggests the inverter chassis itself may not have a dedicated grounding lug. Proper grounding is critical for safety. It is strongly recommended to consult a qualified electrician to ensure the inverter and all connected AC loads are correctly grounded according to local electrical codes.
4.4 Remote Control Connection:
Plug the remote control cable into the designated 'REMOTE' port on the front panel of the inverter. The remote allows for convenient power control from a distance.
5. Operating Instructions
5.1 Powering On the Inverter:
- Ensure all DC and AC connections are secure.
- Flip the main power switch on the inverter's front panel to the 'ON' position.
- The LCD display will illuminate, showing input voltage, output voltage, battery capacity, and load power. The indicator light should turn green.
