Product Description

Introduction 

WLD280 is a solar pump controller which is special designed for solar photovoltaic pump to replace battery with retain water. The direct current generated by the solar module is input into the PHOTOVOLTAIC pump controller and converted into alternating current to drive all kinds of three-phase variable frequency pumps directly. Support the selection of booster module, meet the requirements of inverter low-voltage work, reduce the number of solar panel configuration, save customers' economic investment; Built-in efficient MPPT tracking algorithm, and with automatic dormancy, overpressure and underpressure protection functions, with local conditions, water-saving and energy-saving advantages, widely used in farmland, orchard irrigation, water tower replenishment and other occasions.

Functional Features

Adopting advanced MPPT technology, make full used of the power generation efficiency of solar panel array;
Support photovoltaic/city two kinds of power source independent selection and automatic switching;
It can automatically adjust the water flow along with the intensity of sunlight;
Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control though water level;
Water shortage protection: prevent pump from dry running when there no water;
It can also enter automatically 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);
With various protection functions, improve the reliability of whole system and special designed for water user, it is widely used on various application and easy operation.
