Initial in-house implementation:
Eco Mode Off (or Away Mode Off)
Energy consumption is hard to predict, so:
- Keep battery always charged - Use Self-Use mode
Eco Mode On (or Away Mode On)
Energy consuption is almost constant during late evening, night and early morning.
There is a place for optimizations, for example:
- Postopone battery charging until hourly prices drop to the minimum - Try Feed-In Priority Mode
- Schedule discharge slot if solar production forecast shows sunny next day. Discharge the battery at peak hour.
