Tesla Powerwall products (including Powerwall 3) have a massive failure rate. Seems like 10% over lifetime. Shoddy technology compared to the leading competitors, especially the inverter. They should go back to white labeling cheap Delta inverters.
In the industrial world, where the real money is to be made, a high failure rate of the individual units isn't an issue.
You simply overspec the site by perhaps 2% to allow 2% of units to fail and the whole system is still working to specification.
Then you design the replacement procedure for the battery or inverter modules to take 10 seconds per module and swapping the faulty ones out only takes a few man-hours per year even for a gigawatt scale installation.
