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: Solar pump system is modular and can be upgraded over time
The components that make up the solar water pump system are very modular. They can be replaced and upgraded according to their needs. Additional solar panels can be added if overcast, low light and performance requirements are increased. If more water is needed every day, batteries and additional panels can be added. If more volume is needed, the pump can be replaced with a higher power model with higher flow rate.

Worth buying

I use this 1.5kW solar pump inverter to irrigate my 1200 square foot garden. The garden is about 30 meters away from the pond. I'm afraid that pond impurities will damage the pump, so I cover the inlet with a filter, connect the hose and throw it into the pond. It works perfectly. I suppose if the sun is strong enough and can also buy solar panels to replace the battery. Very convenient to use. Worth buying.
