Virtual Battery Allocation for Aggregator

• This feature is exclusively available in Sweden.

• The function enables virtual partitioning of ESS into two independent operational units:

  • The virtual battery can participate in CheckWatt VPP's frequency regulation services

  • Remaining capacity continues to be optimized by Sigen algorithm

No.	Parameter name	Description
1	Virtual Battery Allocation for Aggregator	When set to , configurable parameters for the Aggregator-dispatched virtual battery become available.
2	Total Battery Capacity	Total battery capacity of the energy storage system.
3	Virtual Battery Capacity	Configure virtual battery capacity allocated for Aggregator dispatch. （Virtual Battery Capacity≤Total Battery Capacity）
4	Allocation Ratio for Aggregator	The percentage of virtual battery capacity relative to total battery capacity, quantifying dispatch rights allocation.
5	Inverter Rated Max Active Input Power	Maximum allowable output power of the inverter.

9	Battery Rated Max Charging Power	Maximum allowable charging power of the battery.
10	Battery Max Charging Power	Set the maximum inverter output power allocated to the Aggregator-dispatched virtual battery. （Battery Max Charging Power≤Battery Rated Max Charging Power, Battery Max Charging Power≤Inverter Max Active Input Power）
11	Battery Rated Max Discharging Power	Maximum allowable discharge power of the battery
12	Battery Max Discharging Power	Configure the maximum discharge power limit for the Aggregator-dispatched virtual battery. （Battery Max Discharging Power≤Battery Rated Max Discharging Power， Battery Max Discharging Power≤Inverter Max Active Output Power）

Virtual Battery Setting

No.	Parameter name	Description
1	Operational Mode	Configure virtual battery operating mode.
2	Charging Cut-off SOC	Terminate charging when battery reaches the preset value (e.g. 80%) to prevent overcharging and extend battery life. The setting shall not exceed the system's charge termination SOC.
3	Discharging Cut-off SOC	Discharge termination activates when battery reaches the preset threshold (e.g. 50%) to prevent over-discharge and maintain battery health. The setting shall not fall below the system's discharge cutoff SOC.
