Pump Inverter
ZK SG320-4K0GB-2S Solar Pump Inverter description
Solar pumping system converts solar energy directly into electric
energy, and then drives motors to drive water pumps to pump water
from deep wells, rivers, lakes and other water sources. The system
consists of solar panels, solar pump inverter and water pump.
The solar pump inverter operates in dual supply mode either with a
three phase input supply from the grid or with DC input supply from
PV cells. A four-pole changeover switch enables switching between
the two supply modes. At a given time only one supply (PV cell or
grid) will be connected to the drive.
Solar Pump Inverter Features
1.Simplified commissioning.
2.The inverter automatically sleeps when the water level of the
reservoir is high.
3.It can prevent the water pump from dry pumping without water when
the water source is dry.
4.when the light becomes strong (such as sunrise), it will exit the
sleep.
5.Built-in mppt function with high efficiency.
6.The drives can be equipped with remote monitoring options,
reducing maintenance trips to the
site.
7.Digital control for fully automatic operation, data storage and
protective functions.
8.Embedded pump-specific features such as dry run detection,
minimum power input protection,
maximum current protection, stop frequency running protection.
