AC/DC Solar Surface Pump
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
- Air 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 Surface Pump come in?
The AC/DC Solar Surface Pump range covers 10 models from 600 W to 2200 W, with system voltages of 72 / 96 / 144 / 192 / 280 V.
What maximum head and flow can the AC/DC Solar Surface Pump reach?
Top models reach up to 40 m maximum head and up to 60 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 Surface Pump 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 Surface Pump 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 IP55 and the controller is rated IP66.
What water conditions can the AC/DC Solar Surface Pump handle?
It is rated for water temperatures of 0–40 °C, sand content ≤ 0.05 % (≤ 500 g/m³) and pH 5–9.
