Why is "Predicted PV" so high?

[mudge]

I have integrated predbat with Solcast via the Predbat direct method for a 7.2 kWp PV system and a 5 kWh inverter (following the advice for hybrid inverters in the documentation and setting both my AC and DC capacity to 7.2 kW) but my predictions seem to show an unexpectedly high predicted PV value beyond what I could reasonably generate:

Looking at the HA states, I see the following entities:

Entity	State
predbat.base10_pv_energy	27.043
predbat.best10_pv_energy	27.043
predbat.best_pv_energy	69.22
predbat.pv_energy	69.22

The forecast solar production from HA's default Energy dashboard has a sensor.energy_production_today value of 26.285 kWh which seems more realistic.

Is predbat saying it is predicting 69 kWh of production today or am I misreading what predbat's pv_energy means?

pv_energy is the '50%' forecast from Solcast.

I think the reason for this is that predbat is predicting the PV energy for today AND to the end of the forecast plan. All of the predbat future forward sensors work like this, they are not just 'today' forecasts.

If I look at my own predbat.pv_energy, its 122kWh, way more than a day's generation.
If I look at the attributes it is forecasting from now (17:20 on 15/6) right through to 17:15 on 17/6:

The forecast is also at 5 minute granularity which is I guess what it gets from Solcast

I think you're right and I was missing that the predicted PV energy is for the entire prediction duration (which is roughly 48 hours).

I've added a clarification about the forecase_hours to the documentation.
