What will happen to my account if I don't sign up? Im looking at maybe seeing how things go and compare between WW and just setting my battery to charge at a fixed time slot. Might sign up if I can see a difference.
For me it's about savings. Do you have any figures of how much WW might save? I know it's difficult. I'm just going to be setting my battery to charge at 2-4am as the prices will be cheaper anyway. I might not pick up on the best slot (I'm on agile) but it'll be better. The only thing I would be missing is my extra back up charge before the peak time.
I'm Growatt too so I think there is less features for WW than other manufacturers and in the future.
