On and off grid solar system working way:

  1. Inverter transfer solar panel DC current to AC current, supply solar power to run loads directly, if solar power is excess, the power will charge to battery automatically. When the battery power is full also, inverter will send the excess power to grid. grid power to the load(by pass).
  2. When the grid shut down, it will switch to off grid status, transfer solar DC power to AC power,supply solar power directly to the load.When the solar panel can not provide enough power to the load, it will use battery power.
  3. When the solar panel only generate few power, it will switch to grid, supply.
