Possible to connect V2L Car to Inverter (DC Coupled)?
I'm wanting to use some of the 77Kwh Battery in the car to cover all peak time usage of electic during the winter (Summer is fine with solar)...
I'm on Octopus intellient so have 6 hours overnight to recharge the batteries to full; ready for the next day.
Senario; during the day, if the Sunsynk batteries have drained to say 20% - plug a 2 or 3kw battery charger in to the V2L Car that is connected directly to the Sunsynk batteries. This will charge the batteries and/or supply DC to the inverter depending of load.
Add some Homeassistant logic to disconnect the charger via a DC Relay if SOC exceeds 30% to balance battery drain, or if the BMS errors, and disconnect during cheap rate when the inverter is charging the batteries.
Even with efficiency loss 40p vs 8p I think it could be worthwhile?
Would this work, any recommended battery chargers in the UK, thoughts, anyone does this already?
tbh; it a lease car so has no effect to me. Also latest research shows that cycling the batteries a little every day actually improves them.
