AC/DC Solar Submersible Pump (High-Flow)
Engineering note. Maximum head and maximum flow are curve endpoints, not one simultaneous duty point. Final selection is verified against your total head, required flow and solar resource.
- Permanent-magnet brushless motor + intelligent MPPT (auto start/stop, soft-start)
- Controller LED display: voltage / current / power / speed (RPM) / error code
- Oil cooling
- Full protection: over/under-voltage, overload, over-current, dry-run, reverse, over-temp
- Runs directly off PV modules — no batteries required
- Cast-iron / SUS304 wetted parts (SUS316 optional for corrosive water)

Frequently asked questions
What power and voltage options does the AC/DC Solar Submersible Pump (High-Flow) come in?
The AC/DC Solar Submersible Pump (High-Flow) range covers 4 models from 1100 W to 2200 W, with system voltages of 144 / 192 / 280 V.
What maximum head and flow can the AC/DC Solar Submersible Pump (High-Flow) reach?
Top models reach up to 14 m maximum head and up to 56 m³/h maximum flow. These are curve endpoints, not one simultaneous duty point — the exact model is selected against your required head, flow and solar resource.
Does the AC/DC Solar Submersible Pump (High-Flow) need batteries to run on solar power?
No. It runs directly off PV modules through an MPPT controller (>99% tracking efficiency), and as an AC/DC hybrid it can also run from 220 V AC mains (90–240 V, 50/60 Hz) or a generator via an external transfer switch — no battery bank required.
Is the AC/DC Solar Submersible Pump (High-Flow) protected against dry running?
Yes. Built-in protections include Overload, Over-current, Under-load, Under-voltage, Reverse-connection, Over-temperature (thermal), Dry-run / low-water, Soft-start. The pump motor is rated IP68 (submersible motor) and the controller is rated IP66.
What water conditions can the AC/DC Solar Submersible Pump (High-Flow) handle?
It is rated for water temperatures of 0–40 °C, sand content ≤ 0.05 % (≤ 500 g/m³) and pH 5–9.
