Constraint-Aware Solar MPPT Evaluation Using a Feasible-Power Reference and Pack-Terminal Energy

This paper introduces a constraint-aware evaluation framework for solar-battery MPPT. A pre-action, state-conditioned feasible-power reference distinguishes source-side tracking loss from intentional curtailment imposed by battery, protection, converter-current, and thermal limits, while pack-terminal energy measures useful delivered energy. Using equal-budget training-only tuning and independent paired uncertainty testing, 1,708 simulations of a nominal 30 W, 3S1P charger showed a positive mean IncCond-minus-P&O pack-energy difference across all four held-out profiles. The result is conditional on the modeled domain and does not claim universal superiority or hardware validation.
