Open the live energy-flow and battery pages, and note the current battery percentage.
- 01Check battery state of charge, operating mode and any scheduled charge or discharge period in the app.
- 02For charging, confirm there is surplus solar after household use. Low solar or high home consumption can leave no excess energy for the battery.
- 03For discharging, check the minimum state of charge and backup reserve. The battery should normally stop at the configured reserve.
- 04Check time-of-use, backup, retailer or virtual power plant controls that may intentionally hold or dispatch the battery.
- 05Record any warning or alarm. If the behaviour continues through a clear sunny period, create a ticket with the energy-flow and battery screenshots.
ImportantBattery temperature, grid conditions and built-in protection can temporarily reduce charge or discharge power.
