Thinking of switching to Octopus but concerned that only 4 hours off peak may not be enough for the car and the Powerwall battery.I just Twitter them and then I received an email to invite me to the Go Faster tariff, I have now switched with my 4 hours cheap energy starting from 20:30 😃😃
4 hours I’m assuming would put c28kw back into the car but not sure whether this would be affected by the 10kw or so going into the battery at the same time...
