Vehicle to Home Battery

[johnb80]

Every year we consume a large amount of energy on Christmas day, 2 ovens, the hob, heatpumps running etc, this year was no exception and as I've done before, I connected our MG5 up to charge our home battery.

Total consumption for the day was just over 74kWh. This was satisfied with 31 kWh from home battery and 43 kWh from MG5. The car link made a saving of £8.36 of the full price electricity we would have used had the MG5 not been connected. Not mega bucks but worthwhile if you already have access to the power supplies/charger to link the car to the batteries.

You could have used the free 8 hours from Uswitch and kept the house battery topped up.

It doesnt work correctly with Intelligent Octopus GO and apparently only refunds your average use. My average use is zero so it wouldnt really help. I'm very happy with my £5.18p spend for heating, hot water and cooking, seems a bargain to me.

That's a lot of leccy, about 15 days of our normal usage. (We do have gas CH though unfortunately.)

Were around 40 kWh per day including the heatpumps and 2 x EV. I'm happy with the battery and off peak rate etc it makes it more comfortable Its the ovens and hob that really hammer it on Christmas day along with heating 24 hours etc.

We have heating 24hr a day here as well at the moment, mostly solar powered and the wind continues the heating through the night .... it's the HVAC that uses the power over here at the moment .... even the tap water is close to shower temp ....

how do you get the car to power the house?

how do you get the car to power the house?

Use a 230v adapter plugged into the MG5 and enable discharge. Plug a LifeP04 3 kw battery charger into the MG and connect the output of the charger to my 28 kWh house battery. The net result is a 3kW continuous discharge from the car and it being fed into the house via the Victron inverters. Dead easy, works a treat. Doing this way allows the full house to be powered and any huge loads (ovens & heatpumps) can run on the house inverters as normal the car just trickle feeding 3 kW into the system every hour.

I made a thread here back in May on how to make a cheap one work the way you want Converting a non working V2L to a 7kW supply from my MG4

Mine is the poverty pack MG4 51, but they all use the same CCS 2 plug and resistor sizing
