1. Battery Connection:
   • Connect the 12V battery bank (recommended 100/200/300Ah) to the battery terminals on the inverter. Ensure correct polarity (+ to + and - to -).
   • The battery voltage range should be 10.5-16Vdc.
2. Solar Panel Connection (PV Input):
   • Connect your solar panels to the Photovoltaic (PV) input connection socket.
   • It is recommended to connect photovoltaic modules in series to increase the voltage.
   • Ensure the solar voltage range (Vmp) is 30-240Vdc, with a maximum open-circuit voltage (Voc) of 300Vdc. Max PV input current is 15A.
3. AC Input Connection:
   • Connect the AC mains power or generator to the AC input terminal.
   • The inverter accepts 230VAC, 50/60Hz.
4. AC Output Connection:
   • Connect your household appliances to the AC output terminals.
   • The inverter provides 230VAC, 50/60Hz pure sine wave output.
5. Communication Ports (Optional):
   • RS485-1: External Communication Interface (e.g., for WiFi module).
   • RS485-2: Communication Interface for BMS (Battery Management System).
6. Grounding: Connect the inverter to a reliable earth ground using the designated grounding terminal.

5.3. Initial Power-Up

• Once all connections are secure, switch on the battery breaker first.
