DC Voltage booster-low voltage input and high voltage output Manufacturer

DC Voltage booster-low voltage input and high voltage output

It is use to booster low voltage input to high voltage to meet solar pumps system application which need high voltage using.

For example, For 1/3 phase 220VAC pumps, it should be request Vmp ( working voltage) is 310VDC, Voc ( open loop voltage) is 350VDC.

For 3 phase 380VAC pumps, it should be request Vmp 540VDC, and Voc 620VDC.

To order to get high voltage output from solar panels, we always connect solar panels in serial.

for 37voc solar panels, we need do 10 pcs solar panels connection in serial to get 370VDC, and need do 17 pcs solar panels connection in serial to get 629VDC.

And it will cause big investment for small power solar pumps system, and also make it difficult to promote this very good green energy solar pump system solution for people who need more water but less of grid power.

1. Wiring must be carried out by qualified electrical professionals, or it may cause electric shock or fire.

2. Before wiring, make sure the input power has been cut off, otherwise may cause electric shock or fire.

3. The PV array selection should be reasonable, otherwise it may damage the device.

4. Do not change the wiring in the power, otherwise there is a risk of electric shock.
