If your installation is dedicated to backup use, you can set the SOC for backup of your next inverter-chargers to 100%. This keeps the battery fully charged and reserves its capacity for use during a power outage, rather than for daily energy optimization or self-consumption. This setting is useful when your priority is to ensure that the maximum amount of stored energy is always available to supply critical loads when the grid is unavailable.
If the SOC (state of charge) is set to 100%, it is possible that power consumption from the grid or your generator will be higher.
