Specifications
Product Description
The Lorentz PS2-1800 C-SJ3-18 Submersible Solar Pump is a complete system ready to operate in 4” wells. It integrates the PS2-1800 controller with MPPT, the ECDRIVE 1200/1800 brushless motor, and the PE C-SJ3-18 centrifugal hydraulic unit in AISI 304 with a check valve. With a maximum flow rate of 4.0 m³/h and a head of up to 80 m, it delivers water with high efficiency, low maintenance requirements, and total reliability for residential and agricultural uses.
Main Features
- PS2-1800 Controller with MPPT: optimizes solar production and allows control and monitoring.
- PV window: Optimal Vmp > 102 V; max. input voltage 200 V.
- Maximum current to motor: 14 A. Max. efficiency: controller 98%.
- ECDRIVE Motor brushless, water-filled, IP68, high efficiency (up to 92%) and maintenance-free.
- Hydraulic unit PE C-SJ3-18 in AISI 304 with check valve; max. hydraulic efficiency 54%.
- System performance: 4.0 m³/h and 80 m under optimal conditions.
Advantages or Benefits
- More water per kWh thanks to MPPT tracking and high-efficiency electronics.
- Integrated protections (reverse polarity, overload, overtemperature) and input for dry well.
- Silent and reliable operation with sealed IP68 brushless motor, free from periodic maintenance.
- Ready for battery use: deep discharge protection integrated in the controller.
- Lorentz modular architecture: independent replacement of controller, motor, or hydraulic unit.
Purpose or Applications
Water supply for isolated homes, tank filling, gravity irrigation, and transfers on farms. Suitable for medium lines and heads up to 80 m with clean water.
