MPPT solar pump inverter 18kw ac drive frequency inverter vfd
1. VEIKONG solar water pump system is essentially an electrical
pump system in which the electricity is provided by one or several
PhotoVoltaic (PV) panels. A typical solar powered pumping system
consists of a solar panel array that powers an electric motor,
which in turn powers a bore or surface pump.
2. What is solar pump inverter?
A solar inverter or PV inverter,solar pump inverter,solar pump
controller,solar water pump inverter,solar pump drive,solar water
pump controller,solar mppt vfd,solar mppt frequency inverter,solar
frequency inverter,solar pump vsd,solar frequency inverter,solar
vfd are all key words
IT is a type of electrical converter which converts the variable
direct current (DC) output of a photovoltaic (PV) solar panel into
a utility frequency alternating current (AC) that can be fed into a
commercial electrical grid or used by a local, off-grid electrical
network.
It is able to convert DC voltage coming from solar panels into AC
voltage for powering any pump driven by a three-phase motor.
Pump speed is constantly adapted to available solar irradiation
thus maximising the amount of pumped water and making possible
operation even in conditions of low sunlight.
It also offers complete pump protection against surges, overloads
and dry running.

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,l total VOC less than Maximum DC voltage of
inverter and Solar panel vmp is recommend 530V for 380V pump and
305V for 220V pump
