positor1 BT with a SmartHub 2, it's the most recent one they do (apparently 3 is coming).
THALL My other fear would be they treat everyones battery like a powerwall and use it for grid balancing. The prices might be really great but again increased cycles affecting its life.
I am just being over cautious im sure and I am happy to see new tariffs. Today I intend to switch to Flux for example.
My inverter limits the rates anyway, so even if they were sat there charging and discharging all day long, it wouldn't add excessive wear. I doubt they would need to anyway, I expect it wouldn't be wildly different from how I'd use it.
Will have to see how the offerings compare including vs stuff like Flux where I get total control.
