I’m based in the UK and have been watching this forum for many months. I did a lot of renovation to my house and added roof mounting for 20 panels. I have already fitted 10 East facing panels and the other 10 will all be South facing (Panasonic 335w and Enphase Micro Inverters IQ7X). I planned to also add 9.6kW battery storage system to make it worth while in storing my produced energy (I have a Zero Export limit by the local DNO). My plan is to cover my home electrical requirements during the afternoon and evening when the cost of electric is at its highest.
Recently i have been looking at the newest technology of Vehicle to Grid (V2G) and thinking that rather than buy a 9.6kW Battery system (AC Coupled) which will cost around GBP 10,000 and also an electric car later…why not skip on the dedicated home battery system and just go with a 40kW battery storage of the electric car. With V2G smart chargers like the Quasar-dc-charger https://wallbox.com/en_uk/quasar-dc-charger we would only use the electric vehicle for local school runs and shopping and it would always be plugged in to the home charger from 16:00 every day.
making use of the limited UK solar power generation together with night time cheap rate Electric from the utility company between 00:30-04:00 it should be possible to discharge the vehicle battery to run the home in evenings and then charge up to a required % to cover the next days vehicle mileage and based on the forecast sun and solar production.
Do you guys have anything like the V2G on your market? I think this is a real revolutionary idea and the way forward for many homes that have electric vehicles. The utility providers here are starting to look at this technology but want to commercialize it to their benefit, so try to tie you to they higher fixed tariffs so that you pay for their electric and allow them to export your vehicle battery power out to the grid during the high load periods! There are some incentives being offered but the bottom line is they get you to supply and pay for the resource (vehicle battery) and provide a way for them to manage their load balancing at lower costs to themselves. Great for them but not so great for the consumer.
Best regards from the UK!
