This is our cost‑effective 4‑inch simple‑version solar submersible pump, equipped with reliable brushless DC motor and separate external MPPT controller. It delivers stable performance with competitive price for off‑grid water lifting projects.
 
The brushless motor ensures low heat generation, low noise and long service life. The external MPPT controller optimizes power harvesting from solar panels, improving working efficiency under different sunlight conditions. Standard 4‑inch pump diameter fits most common 4‑inch deep well casings. The pump body adopts stainless steel material for rust‑resistance during long‑term underwater operation.
