60V To 90V DC Input 5 Times DC Voltage Booster For Solar Pumping
ZK LV60-90 DC voltage booster mainly feature:
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.
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.
Molde number and selection:
LV40-70 design for "L" (1/3phase 220Vac) inverter, input voltage range :40 to 70Vdc.
Output will be 200V to 350VDC.
LV60-90-2T design for"L" (1/3phase 220Vac) inverter, input voltage range :60 to 90Vdc.
Output will be 300VDC to 450VDC.
LV60-90 design for"H" (1/3phase 380Vac) inverter, input voltage range :60 to 90Vdc.
Output will be 480VDC to 720VDC.
Application:
Low voltage drive device for small solar pump system solar pump inverter, 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.
Now our company has developed a new technology to solve this problem. We manufacture low voltage boost device (Model: LV60-90) to convert low DC voltage to high DC voltage to meet the voltage of solar pump inverter. Meantime, this new system avoids the danger of high DC voltage from solar panels
Make sure the DC voltage from solar panel meets input voltage of low voltage drive device.
For example, if your pump is 750W, 3phase, 380v, use our inverter 750W ( 3phase, 380v,DC input voltage range is 450v-750v) it need minimum 1120W solar panels . We use 280w/pcs solar panel, vmp 37V, voc 44V. Total need 4pcs, 280w solar panel.
