It’ll soon be 24 hours since the battery and solar went live here and today’s been a nice sunny day to give it a good test. Already the battery is full for later, the house doesn’t want much power and the panels, whilst not at their 4.050kW peak are already producing a nice 3.61kW which (with nowhere else to go) is gett8ng sent out to the grid. That’s actually frustrating because the facility to be paid for that export hasn’t been set up yet by the delivery network operator. Still, a good start.
Well, it’s an imperfect solution but it’ll do right now: plugging the car in means the house is now taking 6.38kW. The solar produces 3.54kW of that, the inverter then takes a further 1.79kW from the battery and that leaves 1.4kW being drawn from the grid (at 12.965p/kWh). The car will be back to 80% full inside an hour and then the home battery should top itself up again from the afternoon sun. It proved what I thought would happen so it’s a valuable exercise at a cost of 13p for about 25 miles
