Step-by-Step Profitability Analysis

Charge profit = λ − p_buy/√RTE − degradation per kWh. Discharge profit = p_sell·√RTE − λ − degradation per kWh. Green = active action · Red rows = missed discharge opportunity (profit > 0 but idle/charging).

Step	Time	Price	Feed-in	PV kW	Consump kW	Power kW	Mode	SoC kWh	Disc profit	Chg profit

Terminal price λ = — €/kWh (re-computed; integration may use rolling shadow price) · Break-even discharge: — €/kWh · Break-even charge: — €/kWh

Minimum Spread Analysis

How much price spread is needed for arbitrage to be profitable, given your battery parameters?

🕒 Optimizer Run History

One row per 15-min optimizer run. Highlights deviations between DP output, effective mode (after hybrid/commitment logic), and the published setpoint.

Time	Ctrl mode	DP mode	DP kW	Eff. mode	Eff. kW	Setpoint kW	SoC kWh	Price	Shadow λ	Grid kW	Commit

⚡ Real-time Setpoint Log

One row per setpoint change from the ~5 s real-time loop. Yellow = setpoint deviates from schedule. Red = SoC limit blocked the action.
