60Vdc 90Vdc Increase To 480Vdc 720Vdc Booster Low Voltage Device
Model:LV60-90
DC Voltage booster-low voltage input and high voltage output
It is use to increasing 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.
Low voltage booster device is specially for small power solar pump inverter with low current and high voltage, especial for 0.75kw, 1.5kw 220V pumps, and 0.75kw, 1.5kw 380V pumps. Input voltage is DC60-90V or DC40-70 can work normally, output voltage is 5~7 times of input voltage. Output voltage changes according to input voltage so that solar pump inverter can track the maximum power of PV arrays.
We design and develop DC voltage booster device for increase low voltage to high voltage for save solar panels using,for money save.
There are two models DC voltage booster can help us reduce solar panels investment.
LV60-90 design for"H" (3phase 380Vac) inverter, input voltage range :60 to 90Vdc,output will be 5 times 480VDC to 720VDC and 8 times 480 to 720Vdc.
