Features

Solar pump inverter adopts advanced MPPT control technology, real-time detection of solar panels power voltage, tracking the highest voltage and current, efficiency is as high as 98%.
It can enter automatically to sleep mode when the intensity of sunlight is weak, as well as can exit the sleep mode when the intensity of sunlight is becoming strong.
Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control through water level.
Multiple power supply design, power input can be solar energy photovoltaic DC power supply (DC 260~350V, DC 450~750V), can also be single phase or three phase AC power, simple wiring.
Smart operation, water level detection and operation panel to prevent overflow, dry pumping.
Protect itself in trouble and improve the reliability of whole system.
The bypass- AC source which runs automatically when the sun is Not sufficient or absent.

solar pump inverter wiring application

Tips: The difference between solar water pump inverter and off grid inverter
Off grid inverter: because the DC loop is equipped with a battery, DC side voltages will not fluctuate greatly with the intensity of the light, so the AC side can output a regulated and stable frequency power supply within the rated capacity of the inverter. It can carry any load, as long as the battery capacity is properly configured, the load can be continuously and stably operated for 24 hours.
Solar pump inverter: no battery, so the AC output voltage is not stable, ordinary load can not work normally, can only drive the pump. The pump can work at low pressure because the inverter reduces the frequency at low pressure, the low pressure and low frequency, the pump can still work normally, and it is a principle to work with the frequency inverter with the water pump.
