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.

Tips: Solar pump system vs. ordinary pump system

Unlike the ordinary water pump system which uses AC as power supply, solar water pump system uses DC power output from solar array as power supply. The output of solar array is a strong non-linear DC power supply, which is greatly affected by sunshine, ambient temperature and other meteorological factors. In order to realize the maximum output power potential of PV array under any sunshine, ambient temperature and other conditions, a controller which can make the power supply and load work harmoniously, efficiently and stably is needed. The solar pump inverter is to achieve this function, mainly to achieve MPPT (maximum power point tracking), inverters and some protection functions. The solar pump inverter drives the motor and water pump. The load of the system can be adjusted by adjusting the speed of the pump.
