    SolarEdge sets inverter efficiency record with new technology platform


    SolarEdge’s HD-Wave inverter broke the California Energy Commission’s record for inverter efficiency..

    The inverter, which was announced in September 2015 but is only now seeing wide-scale rollout, tested at 99% weighted efficiency while the competition clocks in between 96-98%. Arguably more important than the efficiency record, is the new technology in the inverter – an “electronics based conversion topology.” SolarEdge says that because of their distributed switching and digital processing of the sine wave, they’re able to more efficiently convert electricity from DC to AC. With this new infrastructure, SolarEdge says inverters can evolve beyond mechanics to the speed of electronics. Think of televisions moving from cathode tubes with big magnets to flat screen electronic machines.

    The greater efficiency means using 1/16 the number of magnets and copper and cutting heat dissipation by half, allowing for a 2.5x smaller aluminum block for cooling. The size and weight – 17.7” x 14.6” x 6.8” and 25.3 pounds – make it half as big as comparable inverters and installable/replaceable by a single person instead of two.
