The RI-ENERGYFLOW-3P-SERIES-50 range forms part of an expanding family of inverters from Rayleigh Instruments.

These inverters are designed for small industrial and commercial projects. With fuse-free design, optional AFCI function and other multiple protections, ensures a higher safety level of operation.

A maximum efficiency of 99% with a maximum DC input voltage of 1100V, a wider MPPT range and a lower start-up voltage of 160V, guarantees an earlier generation of power and a longer working time. An advanced ventilation system also ensures the inverter dissipates heat efficiently.

50% DC input oversizing capability allows users to increase significantly the power output by adding extra solar panels.

10% AC output overloading enables this inverter to be operated at its full capacity by adding extra reflections from the backside of bifacial panels, thus maximizing solar-powered energy generation, giving you a higher yield.
