Solar Pumping System / Capacity Diagram 6kWh/m²/day, 1800Wp solar array. Controller PS1800 • controlling of the pump system and monitoring of the operating states • mounted at surface (no submerged electronic parts) • two control inputs for well probe (dry running protection), float or pressure switches, remote control etc. • automatic reset 20 minutes after well probe turns pump off • protected against reverse polarity, overload and high temperature • speed control, max. pump speed adjustable to reduce flow rate to approx. 30 % • solar operation: integrated MPPT (Maximum Power Point Tracking). Calculation of system performance is based on: - non tracked PV-generator, (see ETATRACK for increasing performance) - 11h standard solar day - ambient average temperature of 30°C. System Performance An irradiation value and the required head in meters are given for a certain solar pumping system. Motor The LORENTZ submersible motor, type EC 1200-C is a 2 pole synchronous brushless DC motor. Slide ring bearing and ceramic trust bearings are water lubricated.
