Inputs for tomorrow

Battery SOC now (%)Expected house use (kWh/day)

House-use profile is estimated hourly; change daily use if tomorrow will be unusual.

System model

PV array	6.565 kWp
Panels	13 × Prime 505 W
Battery	2 × EP6 = 11.52 kWh nominal
Battery operating window	10–100% SOC
Battery round-trip efficiency	≥95%
Inverter	FOX H1-6.0-E-G2 · 6 kW
Preferred battery power	4 kW
Panel temperature coefficient	−0.29%/°C

No assumed bifacial gainHourly simulationTwo roof faces

Flux assumptions

Cheap import	14.67p/kWh
Day export	9.79p/kWh
16–19 export	27.81p/kWh
16:00 reserve target	25%

V2 charges overnight only enough to protect the 16:00 reserve under the forecast and expected house load. Deliberate grid-to-export arbitrage is not assumed.

Calibration

Enter actual FOX production after each day. V2 learns a bounded correction factor from recent entries.

Forecast uses Open-Meteo irradiance/temperature, solar geometry and an hourly battery/load simulation. Forecasts remain estimates.
