Product Description

Introduction
Thanks for choosing our product, we will supply you with considerate service as well as ever.
This product is suitable for solar photovoltaic pump system, aimed at environmental and economy market, to replace battery with retain water and without any battery components. Photovoltaic Pump Controller receives the DC which produced by Solar Modules and then transform into AC to drive all kinds of pump directly.
  It is reaction rapidly, little temperature and humidity influence, balance the system's supply and demands, do well in energy-saving, and so on.

Features
1)Through adopting advanced MPPT technology, this product can make full use of the efficiency of the solar cell array.
2)It can automatically adjust the motor speed and the water flow along with the intensity of sunlight.
3)Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control through water level.
Can prevent pump from dry runing.
4)It also can enter automatically to sleep mode when the intensity of sunlight is weak (e.g. the sunset.), as well as can exit the sleep mode when the intensity of sunlight is becoming strong (e.g. the sun rise.).
5)Protect itself in trouble and improve the reliability of whole system.
