Common questions

How close is the C2000 Gen 2 to a plug-in home battery?

Closer than most portables: its cheap-tariff mode can charge overnight and run things by day, which saves money in a similar way. But it cannot feed power into your home wiring, so it can't do the automatic whole-home job of a real plug-in battery.
