State of Charge Control
Different battery chemistries have associated charge and discharge SOC (State of
Charge) versus voltage profiles. Some batteries, such as lead acid, have reasonably
large changes in battery voltage across the nominal operating range of 20-80% SOC,
allowing the inverter to control battery charging and discharging based on measured
voltage. Other batteries, such as Li-Ion, have a very small change in voltage across the
nominal 20-80% SOC operating range making control decisions based on battery voltage
difficult (see Figure 19 for illustrative purposes only). To accommodate battery
chemistries such as these, SOC-based control can be enabled in the Conext XW Pro
under the Grid Support menu in the Configuration tab of the Conext Gateway
web application. When enabled, all SOC-based threshold configurations for transitioning
between operating modes shall take effect, and their voltage-based counterparts shall be
deactivated.
