Plug-in solar is coming. Plug-in batteries should follow | Hacker News

The discussion says plug-in solar for homes should be paired with plug-in batteries or hub devices to improve outage backup and self-consumption.

Commenters debated batteries that act like UPS units, hub hardware that isolates circuits during outages, and systems that shift power across home loads.

EU products and concepts such as Bluetti’s Balcony Transfer Hub, Pila, and Regen were compared, along with concerns about safety and wiring requirements.

California net metering, especially NEM 3.0 and NEM 4.0, rising electricity rates, and utility fees were also central to the debate.
