Putative current raw top-up level (when allowed): 63% (normal min 0%, max 100%).
Flags/status:
[MT] 0% heat battery Maximum Top-up level: 0%
[GI] Grid Intensity gCO2/kWh: 239 (7d mean 185)
[IT] Grid gCO2/kWh Intensity Threshold below which discretionary top-up is allowed: 92.
[F ] expected grid demand from High (peak) / - (normal) / Low (off-peak).
[F B] Enphase AC Battery SoC too high to allow transfer to heat battery, or unknown [b].
[F F] good Forecast PV generation tomorrow.
