Working Principle

• To charge batteries by grid power in priority. When the gird power works as normal,the batteries will be charged by grid powe throug the contoller. When abnormal happend, the solar will start charging the batteries.
• To charge batteries by solar in priority. The solar charge batteries through its controller, and the controller for grid will shut down. When the solar is out of the effective charging range, the grid power will start charging the batteries.
• .To charge the batteries by both solar and grid power at the same time.
• When grid power is disconnected or abnoral happened, the system will switch to batteries to support the loading.
• When the grid power recover, the system will switch back to the grid power to support the loading.
