Good vision. If you know about municipal power companies and solar, I've got that combination and it's 16kWp of battery nightmare. The only saving grace is I'm being good to the planet, if not all that much to my bank balance. We'll never break even, and I'll probably have to replace the SolarEdge crap and crap LG batteries (my second set, still flaky, or something is, I don't know for sure yet what lol), meaning everything except the LG PV panels, which seem fine, with a couple of PowerWalls, costing me yet another $20K. But the one thing that does keep working is that the energy I produce is being used, one way or the other, and it's a bunch (my app says 68.6MWh after roughly 4.5 years), and a lot of it is going straight into our Teslas, so I can feel good about it.
[EDIT: Plus this is in Boston, so under the best of hardware reliability conditions, the productivity of the system is gonna suck.]
