The Solar MPPT Submersible Pumping System (hereinafter short as “Pumping Systems”) mainly consists of the crystalline solar panels, pump controller and small electric submersible pump, etc. The small electric submersible pump is made of the axial submersible pump and a DC permanent magnetic brushless motor, which adopts the stator and rotor double porcelain seal technology to provide insulation and waterproofing treatment. The winding insulation strength is more than 500 mega ohm. The structure of the pump is simple, easy for operation and reliable for its safety and performance.
The Pumping Systems shall be controlled by the solar pump controller, which has a built-in MPPT (Maximal Power Point Tracking) electronic mechanism. The solar pump controller can make the Pumping System acquire more power than average solar pumps and provide the protections against over-current, under-voltage and dry-running.
