Settings for 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.

When using the function "Forecast-based battery charging" together with dynamic electricity tariffs, the optimization target of the system must be set to "Efficient".

Setting

Explanation

Forecast-based battery 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.Configuring the forecast-based battery charging)

Required battery 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 forecast-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 entered value. The energy may be reduced if the battery does not have sufficient free capacity for storage.

Prioritized battery charging

If you activate this function, the battery charge is prioritized over an optional load that you have defined Activating Prioritized Battery Charging).

Shortened forecast period

Shortens the default forecast period from a maximum of 48 hours 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 capacity.

System with PV inverter and battery inverter or PV inverter and hybrid inverter

The forecast-based battery charging function ensures that the otherwise curtailed PV energy is stored in batteries when effective active power limitation is configured in the system.
