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

Frequently asked questions
What power and voltage options does the DC Solar Surface Pump come in?
The DC Solar Surface Pump range covers 21 models from 150 W to 3000 W, with system voltages of 12 / 24 / 48 / 72 / 96 / 144 / 192 / 280 / 385 V.
What maximum head and flow can the DC Solar Surface Pump reach?
Top models reach up to 40 m maximum head and up to 80 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 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), so no battery bank is required.
Is the 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 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.
