General power curve depending on grid voltage.
SOC (State Of Charge) limits can be set for active grid support with battery. If a
limit is reached, the battery is no longer used for active grid support. These can
be found under "Battery SoC Limitation for Grid Support":
-
"Battery SoC Lower Limit" - The battery will not be further discharged when
the lower limit is reached.
-
"Battery SoC Upper Limit" - The battery will not be further charged when
the upper limit is reached.
