+#### Battery group mode

+The group of connected batteries can be controlled in three different modes using the **Battery group mode** select entity:
+
+- **Zero on meter**: The Plug-In Battery will try to keep the power consumption/production of your home at zero. This means that the Plug-In Battery will charge or discharge to maintain a net-zero power balance. This is the default mode.
+- **Charge to full**: All connected Plug-In Batteries will be charged to 100%, regardless of the power consumption/production of your home. When all batteries are fully charged, the Plug-In Battery will switch to the standby mode.
+- **Standby**: Batteries will enter standby mode. This means that the Plug-In Battery will neither charge nor discharge.
+
+The **Battery group mode** select can be found in the P1 Meter device, as the P1 Meter is responsible for controlling the Plug-In Battery. This select entity is disabled by default. See [I can't find entities](#i-cant-find-entities-like-voltage-current-or-battery-group-mode) for instructions on enabling disabled entities.
