### Battery Calibration

Used to make the battery charge level display more accurate. Suitable for systems that have not been fully charged/discharged for a long time. The homepage will show the "Next Calibration Time" for easy checking of the current strategy status.<br>

**How to adjust battery calibration settings**

Main switch: Only after turning it on can you set the calibration method. Calibration methods: AlphaESS provides flexible battery calibration settings

* Calibrate Now: Manually control the calibration behavior. When you click start, the system will immediately perform a full calibration, and you can click stop at any time to interrupt the process.
* Cyclic Calibration: If enabled, the system will automatically perform calibration according to the cycle you set (for example, once every 3 days).
* Scheduled Calibration: Choose a future time point, and the system will automatically complete the next calibration.

{% hint style="info" %}
Note:

* If cyclic or scheduled calibration is enabled, the system will run automatically according to the schedule you set.
* Calibration takes some time; perform it when electrical loads are relatively low.

### Power Support

When enabled, the system provides additional support during short voltage fluctuations or minor disturbances to keep equipment running more stably. In most scenarios, keep the system at the default settings.\ <br>

### Diesel Generator Settings

Used to connect and manage diesel generators. When enabled, the energy storage system will coordinate with the diesel generator to provide backup power or high-load support.

**How to adjust diesel generator settings**

The rated power and frequency settings of the diesel generator are not affected by the generator state and can be set even when the diesel option is off. Control mode and output mode settings are only operable when the generator option is enabled.

* Control modes available: SOC control, time control, or manual control.
* Output modes available: battery charging power mode or diesel generator rated power mode.

### AUX Settings

AUX is a passive switch with two states: closed and open. There is no polarity between the contacts. This function is intended to control the contacts to close or open under set conditions, thereby turning loads on or off.

**How to adjust AUX settings**

Before starting setup, ensure the AUX contacts are correctly wired.

* Click the AUX contact channel to select Channel 1 or Channel 2; up to two devices can be controlled. (Some models only have one channel and thus can only control one device)
* The AUX contact can be set to "Normally Open" or "Normally Closed" mode. When using this feature, select a channel and click the "ON" button to enable that channel.
  * Click "Control Mode" to set the functional mode. The AUX contact provides three modes: ON, OFF, AUTO
  * When selecting Control Mode ON, the normally open contact will close during the set time period. Outside that period, the normally open contact remains open. If no time period is set, this function will be invalid.
  * When selecting Control Mode OFF, the normally closed contact will open during the set time period. Outside that period, the normally closed contact remains closed. If no time period is set, this function will be invalid.
  * When Control Mode AUTO is selected, the normally open and normally closed contacts will be triggered based on SOC and switch settings.
