This page shows the maximum percent-full to top-up to from the grid, if any, for the DHW heat battery.
Diversion plus boost today: 0.002kWh (diversion now 0W, DHW h1d=0.0 h1b=0.0, heat battery h2d=0.0 h2b=0.0)
Heat battery control log entry: 2025-07-10T06:51Z MT 0 GI 201 IT 37 F FRbvx2TN ES 1
Putative current raw top-up level (when allowed): 15% (normal min 0%, max 100%).
Eddi output priority 2: Thermino heat battery.
Flags/status:
[MT] 0% heat battery Maximum Top-up level: 0%
[GI] Grid Intensity gCO2/kWh: 201 (7d mean 126)
[IT] Grid gCO2/kWh Intensity Threshold below which discretionary top-up is allowed: 37.
[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.
[F R] grid is Red (high) intensity, or unknown [r].
[F T] heat battery nearly full or full.
Recent (2/8) full days excluding today when heat battery did not fill [nFFnFFFF]: 25%
Recent DHW cylinder pasteurisation days including today, tank maximally Hot [-------H--------].
