I've heard good stories of Tesla Powerwall, but I've heard enough horror stories to scare me away from that company's RE systems for good.
Browsing the "top" posts of r/TeslaSolar, you start to get an idea for how much of a pain in the ass is to deal with the company once things go pear shaped.
I'm not sure if I'm surprised or not that Tesla engineers didn't stress test their system by putting like, 50 Powerwalls on a string and seeing if the system could handle it.
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?
Not bothering to troubleshoot customer problems seems to be a business strategy these days. One of my jobs is for a security firm that internally takes the attitude that if a small biz with a low ARR comes in with a critical problem, they are just to be strung along until they quit.
I think devs voted to get rid of them because it was often QA and Product ganging up on Dev, but if you’ve never experienced Dev and QA ganging up on Product, you’ve missed out.
Getting rid of QA meant that Product cannot be outvoted except by a walkout. It’s part of why I’m not as loud about DevOps becoming its own business unit. At least it’s 2 against 1 again.
