Product Description
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.

Description & Features
Low voltage drive device for small solar pump system, set an example of LV60-90, Currently, among application of 3-phase solar pump system, the inverter minimum DC input voltage is 450V. In order to meet the voltage of solar pump inverter, many solar panels are needed. In some real application, the power of the water pump is small, and the power of several solar panels is enough for solar pump inverter to drive the pump. But the voltage of several solar panels is not enough to meet the voltage of solar pump inverter, so cause using more solar panels. In this case, much power of solar panels is wasted and it makes the cost of whole system very high.
Solar panel connecting as below: 2pcs connecting in series, total 2 groups
So, total vmp 37V *2=74V (60-90V), voc 44V*2=88V (60-90V), both vmp and voc should in the range 60v-90v)
Make sure total vmp and voc voltage from solar panels between 60-90V.
