Program NO 06 reference:

Battery capacity Suggestion Current
100Ah 20A
200Ah 40A
300Ah 60A

 

Program NO 07 reference:

Battery capacity Suggestion Current
100Ah 50A
200Ah 100A
300Ah 120A

 

3. Recommended Working Logic

  1. Solar power supplies the load first.
  2. If solar power is not enough, battery power will support the load.
  3. If both solar and battery are insufficient, the inverter switches to grid power automatically.

4. Important Notes

  • Always enable BMS communication for lithium batteries.
  • Do not select AGM mode for lithium batteries.
  • Avoid setting charging current too high to protect battery life.
  • PNG mode is the most stable setting for Pakistan market applications.

5. Quick Explanation for Customers

“The system uses solar power first, then battery power, and only uses grid power when necessary. This saves electricity cost and ensures stable backup power.”
