Increased self-consumption through forecast-based battery charging

The Sunny Home Manager increases the efficiency of your PV system by storing the excess energy generated during the midday peak, which is not allowed to be fed into the utility grid due to the active power limitation, in batteries.
By means of the location-based weather forecast, the Sunny Home Manager can predict the solar irradiation for some hours to days and check whether derating losses due to the limitation of PV grid feed-in are to be expected for the current or following day. This means that in the afternoon of the current day only as much PV energy is charged to the battery as to ensure that, with the remaining battery charge, grid-supplied power at night and on the morning of the next day can be avoided. Any derating losses forecast for the following day are avoided by the free storage capacity of the more heavily discharged battery.
