[QUOTE="NozSpark, post: 522973, member: 601"] TBH there's only 1 EV charge point that integrates well with load limiting, solar and battery... and that is the MyEnergi Zappi 2 What they do is monitor the current that coming from the grid, solar and battery... and then, dependant on the charge setting, send the appropriate charge to the car.... so if your solar is working particularly well one day and outputting 6kW, your house is using 0.5kW, then it can limit the charge to the car to 5.5kW Chargers are classified - (roughly) slow <6kW (AC chargers) fast >6kW and < 25kW (AC chargers) rapid >25kW (DC chargers) Normally you can have a 7kW charge point at home on a single phase supply,,, but if you have a three phase supply you can have a 22kW However,,, there aren't many cars that can make the most of a 22kW charge point, most cars only have a single phase charger on board, some you can spec a 11kW charger,,, and a very few have a 16kW and even fewer have 22kW If you're thinking of having a 50kW rapid charger installed then I'm afraid that you'll need very deep pockets, you could easily be looking at £15 - £20k, especially if the local grid needs reinforcement [/QUOTE]
