I find the whole layout perplexing, more like things went off into a marketing plan to show what can be done instead of doing something reliable.

If it can't handle 10 batteries and can't handle updates without backup from the grid, why did they make/sell this setup? Two controllers with ~5 batteries would make a situation where one is active/normal and the other is being the grid so the reliability would be the same as whatever they promise everyone else.. Similarly, he doesn't actually need to be off the grid, his connection just doesn't meet his peak usage so the level of chaos seems to be just to be able to say this is an off grid setup?
