Had a Tesla powerwall for years with never an issue nor have I ever heard of other issues with them. Keeps the house going for about 24hr before I have to fire up the genny. Most often the only way I know we have had an outage is because the Tesla app tells me about it.

Same here. Flawless switchovers. We have two Powerwalls, got conservative with our usage after day one, and got to day three with 20% left.

Interestingly, Suncommon wouldn’t install just one battery. They told me there can be a spike-induced glitch with a single, where the crossover fails. It’s probably super rare, but I thought it interesting that they won’t install singles.
