Before making any connections, ensure all power sources are disconnected.
- Battery Connection: Connect the battery bank (48V) to the inverter's DC input terminals. Ensure correct polarity (+ to + and - to -). Use appropriately sized cables and fuses.
- Solar Panel Connection: Connect the solar panel array to the inverter's PV input terminals. Verify that the solar array's voltage and current are within the inverter's specifications.
- AC Output Connection: Connect your AC loads or distribution panel to the inverter's AC output terminals. Ensure proper grounding.
- Grounding: Connect the inverter's chassis ground terminal to a reliable earth ground.
5. Operating
Once all connections are securely made and verified, you can proceed with powering on the inverter.
5.1. Powering On
- Ensure all circuit breakers for AC output are in the OFF position.
- Connect the battery bank. The inverter may power on automatically or require a button press.
- Connect the solar panels. The inverter will begin charging the batteries if conditions allow.
- Turn on the AC output circuit breakers to power your loads.
5.2. Display and Settings
The front panel display provides real-time information about the system status, including battery voltage, solar input, AC output, and error codes. Refer to the detailed display section in the full manual for specific icon meanings and navigation instructions. Use the buttons below the display to navigate menus and adjust settings as needed.
