I've always wondered why the original Alan Cocconi inverter speed controller used on the Tzero that had vehicle to grid interface wasn't used in the Roadster and future offerings. This AC Propulsion controller that was developed for California's Zero Emissions Mandate was rated at 150 kW, more than enough to handle household loads during a power outage. Any insight from the excellent knowledge pool here at TMC? Wouldn't it be comforting that as long as your Tesla is plugged in at home your immune from power outages? Just view it as a UPS for your home.
