Units policy: every solver-read number is in its SI base unit (V, A, W, Ω, F, H, Hz, °C, °C/W) with no prefix, as a JSON number — 600 µA is 0.0006. Efficiency handles (effNoLoad/effPeak/effMaxLoad), PAE and state of charge are percent 0–100; efficiency on transformers, inverters, PFC, motors and charge pumps, power factor and coupling k are ratios 0–1.
