Seeing the amount of energy that is "wasted" to the grid each day (only to be imported again at night for money) got me motivated to build another smaller battery out of 70 spare 18650 cells (10s7p) to join the bigger one behind it (Installation still pending).
0.7 kWh is not huge, but better than leaving as good as new cells sitting in the corner for years.
Old ammunition boxes make for great cases btw.

Balkon-PV Upgrade ist aufm Dach.

Danke, Habeck! 🤩
Schade, dass "Balkon-Akku" nicht mehr berücksichtigt wurde. Der APsystems EZHI hat natürlich einen DC-Akku-Anschluss und kann (per local API, ohne China-Server) auch 1200 VA einspeisen.
