As per the description, just a general discussion as I'm thinking of leasing an electric car soon, some of the fast chargers can take a lot of juice. Wall boxes for charging are usually around 3.5kW or 7kW for a fast charger and it can take a good few hours to charge a 40kW battery so if you want to fire up your big compressor or welder when your fast charging and as in my case they may both be off the barn spur then that could be a problem. I could always turn charging off but you can guarantee the missus needs the extra charge as the battery is flat and she needs to go out.
I have 10mm2 cable to the barn so may be OK I guess if I up the RCD in the house consumer unit that feeds the barn. I best check the main incomer too.
Next thoughts was semi-off grid battery backed solar PV. The house is getting more automated and rather than keep buying small UPS units where I have various bits of tech then I was thinking about a bigger central UPS. Then I thought if I went the whole hog and had battery backed solar PV I could keep the central heating pumps, fridge/freezers and the bore hole pump going too. I'm not too bothered about feeding excess into the grid, but using the grid if I need more juice. A gennie would be a future upgrade in case of longer term grid outage if I find the batteries don't last.
I've seen a few systems and I'm on the odd forum. I'm in no rush but just thought I would see who else is thinking or doing this.
Cheers
Andy
