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 technical features are integrated in NERA. CENTRIFUGALPUMP ■ Impellers and diffusers in AISI 304 stainless steel ■ Built-in no return valve 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 PUMPSUMMAG Solar ER MOTOR ■ High efficiency permanent magnet motor ■ NEMA standard 4” fitting ■ Resined and encapsulated stator made of AISI 304 stainless steel ■ Kingsbury thrust bearing To connect NERA to the solar system, the STOP MODULE device is available as an accessory. ■ MC4 connectors for fast and easy panels connection ■ Button for pump start and stop ■ Connection for float or pressure switch

MPPT: ALWAYS PUMP SELECTION 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. For the correct...

Max external diameter including cable and cable cover

NERA pump can be installed both vertically and horizontally, as long as the outlet is never lower than the horizontal axis. To ensure proper cooling if NERA is not installed in a 4” well, it is necessary to use a cooling sleeve.
