FWIW, I started a thread here:
to ask about the fact that my TBC charging rate had gone from 3.7 kW to 5.0 kW at the end of Feb 2023. Initially someone at Tesla thought it was to do with grid codes, but when I made contact again I was informed that it was a global (well, maybe just Britain?) decision, and that it had been decided to make use of the full 5 kW rate, and they confirmed that the decision had been taken at the time I'd noticed it.
Which now seems to be a load of balls in view of xWren's experiences. I assumed it had more to do with the fact that Octopus had abandoned their Go Faster tariffs and moved everyone onto plain Go, with one hour less of cheap rate each night.
I continue to be utterly fed up that a piece of kit that I own is not under my control; I do believe in fairness that TBC has been improved somewhat, for example when we've had a couple of sunny days this winter the battery has still charged up to 100% the following night, rather than assuming that we're in the midst of a heat wave as used to happen, and thus failing to charge fully the next night, leaving an incompletely charged battery to cope with a sunless day. But I still - thanks to not sleeping well - check what's going on during the night, and use a combination of switching modes and storm reserve back up to make the system do what I want it to do, not what oh-so-clever Musk thinks it should do. We still desperately need a third "mode", that of "TBC with owner determined "charge to x% tonight" option". It would be so easy to implement, and like xWren if I'd known about the lack of control I'd have never chosen Tesla.
That said, a nieghbour has Solar Edge and for TBC it is utterly useless and doing things which are costing her money.
Powerwall Overnight Charging Rate
We've had a Powerwall 2 for just over two years, and for the first eighteen months (until March 2023) we had five hours per night of cheap rate electricity on the Octopus "Go Faster" tariff. Throughout that period - when using Time Based Control - our Powerwall would charge at a rate of 3.7...
