Product description

The B503DSL series products are suitable for solar photovoltaic water pump systems and are positioned in the environmentally friendly and economical photovoltaic product market, replacing electricity storage with water storage without battery components. The DC generated by the solar modules is input to the photovoltaic water pump controller, converted into AC, and directly drives various water pumps.


Features

This product has the characteristics of high quality, multi-function, low noise, and strong versatility:


Product advantages

• Adopt advanced MPPT technology to give full play to the power generation efficiency of the solar cell array.

• Automatic adjustment of motor speed and water output of the pump with the change of sunlight illumination.

• Automatic dormancy at high water level of the reservoir and automatic restart at low water level to realize automatic water level control.

• It prevents the pump from pumping empty when the water source is dry.

• Automatic dormancy when the light is weak (e.g., sunset) and withdrawal from dormancy when the light is strong (e.g., sunrise).

• With a variety of protection functions to improve the reliability of the system work. Specially designed for water supply users, adaptable to various occasions application, easy to operate.
