DC voltage booster for solar pump inverter 

Specification: DC60-100VDC input, 240VDC to 400VDC output, power750kw, 1500kw.
For 3 phase 220VAC pumps, 400w, 750w, it need 310Vmp, 350Voc input to serve this system. 

For example, if you solar panel specfiication is 300w, 34vmp. 46voc,
it need 8 piece solar panels, and total power will be 2400w.
it need big investment for buying these 8 peice solar panels.

Now if you take this solar voltage booster.
Only 2 piece is OK.
total vmp input is 74V, voc is 92VDC of 2 piece solar panels and power is 600w.
There are 6 piece of solar panels can be saved for 3 phase 400w AC pumps
