Dear Ladies and Gentlemen,
I have a suggestion for extending the functionality of the ESS system: besides the settings - optimized with Battery-Life; - optimized without battery life; - keep the battery charged; - External control; In my opinion, an additional operating mode makes sense "keep priority battery via solar in the charged state + provide additional solar energy to the AC-Out available."
Thus, the battery no longer bogs for days in the weak state of charge around and the existing solar power can be supplied to the consumers after battery charging to 100% and thus be used.
At night, the battery is left unused, the consumers are supplied via the mains; During the day, the battery is first refilled and then the consumers are proportionally operated to the grid with solar power.
I would be pleased if you can check this variant and wish you a nice day!
