11.3.10.2 Setting up Forecast-Based Battery Charging
Forecast-based battery charging is based on the production and consumption forecast of your smart home. The settings
for charging a battery are only displayed for systems with a battery.
Setting Explanation
Forecast-based bat-
tery charging
To create a battery-charging forecast for the next 48hours, the SunnyHomeManager uses
the current day and the two following days by default.
Required state of
charge (SOC) in
terms of forecast-
based charging
Disables the forecast-based charging until the battery is charged to the specified % value
(SoC = State of Charge). If this value is reached, the SunnyHomeManager enables fore-
cast-based battery charging function.
This configuration may lead to derating losses.
The electricity generation and consumption forecast is not taken into account up to the en-
tered value. The energy may be reduced if the battery does not have sufficient free capacity
for storage.
Charging of battery
prior to optional
loads
If you enable this function, the battery charge is prioritized over an optional load that you
have defined.
Shortened forecast
period
Shortens the default forecast period to the current day. This allows more PV energy to be
loaded into the battery on the current day.
This configuration may lead to derating losses.
PV energy may have to be derated on the following days due to insufficient free battery ca-
pacity.
Requirement:
☐ Strings must be configured in the system.
☐ At least 1 battery or hybrid inverter must be configured in the system.
Procedure:
1. Go to SMA SMART HOME Settings and select Active under Storage management via the Home
Manager.
Only select the option if active power limitation is configured in the system.
☑ Another setting option opens.
2. Enter the required value under Required state of charge (SOC) in terms of forecast-based charging.
3. If the battery needs to be charged prior to a defined optional load, select Active under Charging of battery
prior to optional load.
