6.2.4 Site battery monitoring
Use this function to monitor the site battery and the shelter temperature. The SGC controls the power sources (mains or
genset) to make sure that they battery voltage is more than the configured set point.
To enable site battery monitoring, go to Module > Site Battery Monitoring, and tick the box next to Battery
Monitoring.
If there is a mains failure, the site battery supplies the load if:
• The battery voltage is more than the Low Voltage Threshold and
• The shelter temperature is less than the High shelter temp set point.
If the battery voltage is less than the configured set point for low voltage or the shelter temperature is more than the set
point for high shelter temperature, the controller sends a start command to the genset. Once the genset loading voltage
and frequency are more than their minimum set points, the Warm-up delay timer starts. At the end of the warm-up delay,
the timer for the load transfer delay starts, and the genset breaker closes.
The genset operates until the DG run duration timer expires. You can configure a DG run duration timer for the site battery
and the shelter temperature. If the genset starts as a response to the condition of the site battery voltage, the genset
