The most compact and reliable solution for solar pumping applications

NERA solar pumps have been developed to meet the needs of low-power and low-cost pumping systems without sacrificing quality, reliability and performance. For this reason, unique technological features are concentrated in NERA. ■ Impellers and diffusers in AISI 304 stainless steel ■ Built-in no return valve Encapsulated electronics ■ High-efficiency encapsulated inverter ■ MPPT for maximum flow in all weather conditions ■ Overload, overheating and dry-run protected ■ Removable power cable ■ Water level sensor

Helical rotor pump ■ Highest hydraulic efficiency ■ Hard chromed rotor ■ High quality EPDM stator To connect NERA to the solar system, the STOP MODULE device is available as an accessory. It is equipped with: ■ MC4 connectors for fast and easy panels connection ■ Button for pump start and stop ■ Connection for float or pressure switch ■ Surge protection High efficiency permanent magnet motor ■ Resined and encapsulated stator made of AISI 304 stainless steel

MPPT: always the maximum power available Imp Isc Based on the varying conditions of solar irradiation and temperature, MPPT (Maximum Power Point Tracking) maximises the electrical power drawn from the panels and therefore the amount of water pumped. The greater the solar irradiation the faster the pump’s rotation speed, and consequently water flow increases. When solar irradiation decreases (due to clouds or the different times of day), the pump reduces frequency and therefore the flow, but it continues to provide water until the irradiation falls below a minimum level necessary to ensure operation....
