20kw off grid solar generated system

Off grid solar power system gives priority to the solar energy and switches to the grid when lack of voltage or in rainy days. It has batteries back up and could supply electricity at night.

It can be applied to the villa, household, tourist resorts, prairie areas, remote mountain village, no power supply areas, farms, villages, island, highway and any regions to generate electricity. 

It can load household appliances like TV, Air Conditioner, refrigerator, lighting, washing machine, etc.

off grid and on grid difference:

off grid: include battery , solar panel prodce DC voltage pass controller charge battery and pass inverter supply load use.

When no solar panel electricity , will battery supply load use

When have a little solar panel electricity , will solar panel and battery together supply load use 

When no solar panel and battery electricity , will automatic switch city grid supply load use and charge battery.

The off grid solar power system work mode:

Solar panel produce DC voltage and electricity pass controller output rated voltage change battery and supply load use.

When no solar panel electricity , will battery supply load use

When have a little solar panel , will solar panel and battery together supply load use

When no solar panel and battery electricity , the inverter will automatic switch city grid charge battery and supply load use
