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 inverter selection
The solar water pump is not like the pump powered by the conventional AC grid. Because the electricity generated by the photovoltaic module is the direct current, it is required to invert the direct current into a three-phase alternating current for being used by the water pump through the inverter. Then, the solar pump inverter special for PV water pumps should be selected with high reliability and high system efficiency. The capacity of the solar pump inverter must meet the heavy-duty startup of the selected pump. If it is used the highland area, the capacity reduction caused by the high altitude must be taken into account, so as to ensure the long-term and reliable operation of the system. In normal conditions, the power of the solar pump inverter is required to be one stage higher than that of the water pump motor.
