The tech costs more than conventional options upfront, but federal tax credits, new 120V models and strong savings have made them more appealing than ever.

    3-phase 230V 16A is standard here. but you can get up to 30A if the wiring allows it. I’ve never seen a house with only 1 or 2-phase.

      German 3-phase is at 400V, there is no such thing as 2-phase (you’re probably thinking of split phase 110+110 as in NA). So I’d be practically certain your parents have single phase 230V.
