Performance Diagram
The energy storage system can be completely discharged (SOC = 30%) with a power of 100 kW. If by extracting higher power the discharge limit is reached, the remaining energy can be extracted by reducing the discharge power.

Grid connected charging
Maximum charging by PV power
Every 14 days the system will perform an equalizing charge which will take approx. 12 hours.
The cycle life of 4,500 complete cycles (DOD 100% - 30% - 100%) is specified at a charging power of 115 kW max. This is equivalent to a charging current of 150 A. Under this charging method the system can be completely charged within 10 hours maximum.
The charging method generally is depending on the application. We basically distinguish between grid connected systems and PV Hybrid systems used in Off Grid systems.
For grid connected systems we apply multistep charging according to the below diagram. Charging time under this method is about 6 hours.
For island / off grid systems we apply a simple U/I curve in order to absorb a maximum of available energy. Maximum charging power under this method is 270 kW. Provided that there is sufficient energy available the system can be fully charged within less than 4 hours.
