Solar Water Pump System DC 3HP–30HP Off-Grid MPPT Deep Well Submersible Pump

Product details

This solar water pump system works fully off-grid to deliver stable water supply. The full set has solar panels, external MPPT charge controllers and submersible water-filled deep well pumps. This unit runs mainly on solar power. It can draw water in areas without power grids. The system switches automatically between solar power and city power. It uses solar energy first. We make units from 3HP to 30HP. They fit farm irrigation, remote village domestic water and livestock drinking.

Core Advantages

1. Low daily running cost It runs only on sunlight. You pay no fuel or electricity fees. You do not need grid transformers. You can set it up anywhere outdoors without power limits.
2. High solar energy use rate The MPPT tool tracks solar power. Its peak energy conversion rate hits 98%.
3. Full safety protection for the whole machine The controller has auto-stop functions for overvoltage, undervoltage, overcurrent, short circuit, dry run and overheat. The motor uses soft start. It creates no sudden current spikes and extends pump service life.
4. Cheap future maintenance We place the controller on dry ground. You do not need to pull the pump out of wells to fix or replace parts. You can add new functions to the system later.
5. Strong resistance to harsh outdoor weather We build pump bodies, flow channels and shafts with 304 stainless steel or copper. It uses silicon carbide graphite seals and NSK ceramic coated bearings. It runs stably between -15℃ and +60℃.
6. Wide water source compatibility It works for shallow ponds, lakes, water tanks and deep wells. The minimum water depth is 1 meter. Its max head reaches 400 meters, and max flow hits 115 cubic meters per hour.
7. Complete export certifications All pumps pass ISO, CE and RoHS tests. They meet import and export rules for most countries worldwide.
