Solaredge Energy Bank DC coupled

10 kWh (9.7 usable).

 

Nissan Leaf 30 kWh with Indra V2G charger (hacked of course) giving a usable 21 kWh of battery storage.

 

Both are integrated with our Home Assistant based HEMS to allow everything to play nicely together. 

 

I love that! 

Unfortunately there doesn't appear currently to be a V2G available on the market (the ones out there are, I believe, all associated with trials).  Once one comes out I'm sorely tempted to replace our 'second' car (a petrol fiesta) with an ageing leaf (I dont yet have a battery, other than the one in our Kia e-niro which, sadly, isnt bidirectional).

Tesla PW3 (13.5kW) and Gateway for full home backup.

 


Samsung 12kW gen6 ASHP with 50L volumiser and all new large radiators. 7.2kWp solar (south facing), Tesla PW3 (13.5kW)
Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.
