- Vendor: Lorentz
Specifications
Product Description
The Lorentz PS2-1800 HRE-04 Submersible Solar Pump is an integrated 4” system that combines the PS2-1800 controller with MPPT, ECDrive 1800-HRE brushless motor, and HRE-04 helical head in AISI 304/316. It delivers up to 0.71 m³/h and lifts water up to 70 m, with advanced protections and reliable operation in demanding solar installations for supply, irrigation, and livestock.
Main Features
- Reference head 70 m and flow rate up to 0.71 m³/h.
- PS2-1800 controller with MPPT, allowable PV power ~1.8 kW, max. input voltage 200 V, optimal Vmp > 102 V.
- ECDrive 1800-HRE motor (~1.7 kW), brushless, IP68, immersion up to 150 m, maintenance-free.
- HRE-04 helical hydraulics with non-return valve, AISI 304/316 construction.
- Inputs for dry well/remote control and integrated Sun Sensor; option for battery operation.
Advantages or Benefits
- Superior energy efficiency due to MPPT and brushless motor, reducing PV array size.
- Professional reliability: protections against reverse polarity, overload, and overtemperature.
- Minimal maintenance and long service life even in severe environmental conditions.
- Safe water resource management with dry well shutdown and tank control.
Purpose or Applications
Domestic/community supply, elevated tanks, drip irrigation, and livestock. Ideal when good manometric head is required with moderate flow rates and solar power supply.
