200KW off grid system solar system connect method:
1,4 parallels of 20pcs X 310W 24V solar panel to be 480V DC connected in series.
2,4 parallels of 20pcs X310W connect to 1 piece Combiner box(4 to 1),
3,1 piece Combiner box connect 1 route of Controller.
4, The Controller have 4 routes. 4 routes connect 4pcs of Combiner box.
5,Because 1piece Combiner box connected 4 parallels of 20pcs 310W,
So 4 combiner box have 16 parallels of 20pcs 310W solar panel.
6, So 1 piece Controller 4 routes have 16 parallels of 20pcs 310W solar panel.
7, 2pcs controllers have 32 parallels of 20pcs 310W solar panel, total 640pcs 310W solar panel.
8, 2pcs controllers charge 240pcs 2V 1000AH batteries of 480V connected in series,
9,The power from 240pcs batteries of 480V DC connect to 480V DC input of 200KW inverter
10, The inverter will transform 480V DC to be 380V 3phase for project use
