SolarEdge Smart AC Switch with meter communicates wirelessly with the inverter via the ZigBee antenna in the inverter. Not all inverters are prepared for ZigBee; if not, there is always the ZigBee plug-in.
Contains an integrated energy consumption meter and provides energy measurements up to 3kw. Can be switched remotely according to a pre-programmed schedule, or dynamically by the inverter for maximum self-consumption.
