Production Description

48V permanent magnet deep well pump,household agricultural water pump,solar pump is an energy-saving 
And enviromentally friendly pump. it is composed of solar deep well pump,photovoltaic voltage controller and 
Solar panel,which is very useful for water supply and deep well intake in remote mountain ares. it is also con-
Venient,the solar energy absorbs sunlight as energy,and then converts itinto electrical energy,and it is installed 
In a place with sufficient sunlight.


Advantages
Safety,doesn't produce any hamful liquid,gas solid,etc.
Environmental protection.
Solar modules are connected in series and connected in parallelto meet different electricity demand.
Installation and maintenance are simple operating costs are low.
No need for workers supervision,saving man power,working at sunrise and resting at sunset.
