Noted: We suggest solar panel power should be 1.3-1.4 times higher than solar pump power ,
And solar pump inverter power should be higher level than solar pump.
When solar pump distance to inverter higher than 100m,
It should be equipped with Output reactor or higher level power inverter.
For Solar panel,total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend
530V for 380V pump and 305V for 220V pump.
VEIKONG VFD500-PV solar pump inverter benefits:
Solar pumping system including solar pump inverter, solar panels, solar water pump.
When sunshine is good enough, it can convert dc from solar panels to ac, using ac to drive solar water pump to get water from the lakes, well, rivers other places where having water. When sunshine is not strong enough, if there is grid power (or generator) in installation site, the users can use grid power or generator to supply ac power to drive the solar pump inverter to get the water from water sources as well.
VEIKONG VFD500-PV series solar pump inverter also has hybrid function, it can connect with grid power (or generator) and solar panels at the same time. It is available for users if they want to operate the solar pump system 24 hours continually.
In General, solar pump inverter and solar pumping system have the following benefits:
6. How to make the water pump system work without sunshine?
Usually, solar PV water pump system can meet the needs of pumping water.
If there is no sunshine, the system will not work. But out inverter could also support AC input. So, connect the power grid or diesel power generation to the inverter, the pumping system will work. If necessary, keep switch and interface locations during the system design
