Whole-home monitors read the service mains, a feeder, or a handful of channels. They are the choice for solar and net metering, three-phase services, or a single large load such as an EV charger or a heat pump. Some DIN-rail meters from Shelly are built for installers, so check how a unit mounts before you buy. Emporia’s base Vue 3 is listed here because its branch sensors are sold separately.
