For an elementary supply of water EMPO-NI has developed a cost optimized submersible motor driven pump. The stainless steel motor is available with interchangeable stainless steel pumps optimized for pump heads of typically 30m, 85m and 100m (others on request). The set comprises the proven robust passively cooled EMPO-NI SDD1.5kW-425V and a pump head / discharge optimized submersible pump. Runs with any 4 quality PV-panels (60 cells).


  • SDD1.5kW-425V with complete pump specific protection functions (dry-run protection (sensorless, level switch), low speed, etc.) and MPP- tracking, flow meter input, etc...

  • Fully encapsulated IP54 (IP65) passively cooled system for up to 45°C ambient temperature.

  • Dedicated full stainless steel pumps with optimized pump head / discharge selection and robust 3~ motor.

  • PV-panels are not contained in this set.

The graph shows the typical performance curve indicating the pump’s discharge in cubic meters per hour (m³/h) at a given pump head in meters (m). Other pumps with more pump head on request. Please get in touch with our engineering team.


All materials for the stainless steel pumps, motors and the Solar Direct Drive have been carefully selected for robustness and quality to ensure a long life even under harsh environmental conditions. Solar Direct Drives are MADE IN GERMANY
