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.
- **Zero mode**: In this mode, the Plug-In Battery works to keep your home's net power consumption or production as close to zero as possible. The battery will automatically charge or discharge to maintain a balanced power flow. This is the default setting and helps you maximize self-consumption and minimize grid interaction.
- **Zero mode (charge only)**: The Plug-In Battery will only charge to absorb excess solar production, aiming to keep your home's power production at zero. Discharging is disabled in this mode. This is useful if you want to store solar energy for later use, such as during the evening or when energy prices are higher.
- **Zero mode (discharge only)**: The Plug-In Battery will only discharge to supply power when your home's consumption exceeds solar production, aiming to keep your home's power consumption at zero. Charging is disabled in this mode. This can be helpful when energy prices are high and you prefer to use stored energy or sell excess solar production to the grid.
- **Manual charge mode**: 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.

{% tip %}
"Zero mode (charge only)" and "Zero mode (discharge only)" are only available for:

- P1 Meter with firmware version 6.0300 or higher
- kWh Meter with firmware version 5.0100 or higher
