SigenStor EVDC 25 7.5S2
Item number: C00703
Warranty: 3 years
The SigenStor EVDC 25 7.5S2 is a 25 kW bidirectional DC electric vehicle charging module designed for fast DC charging integrated into a home energy system. The device supports V2X (vehicle-to-home/vehicle-to-grid) operation, making it suitable not only for charging but also for energy feed-back scenarios with compatible vehicles. Among the charging modes available is solar surplus energy (PV surplus) based charging, which allows the vehicle to be charged with up to 100% green energy, while in fast charging mode, the system is able to utilize both grid and PV power simultaneously.
At the system level, it is important that the EVDC module can be used with the Sigen Energy Controller. V2X functionality depends on the capabilities of the connected vehicle, and the function can be expanded with OTA updates in line with the availability of related standards. Officially supported vehicle models and schedules are subject to manufacturer announcements.

Functions and operating modes
- Timed charging: the start time of charging can be set.
- PV surplus-based charging: the system uses PV surplus energy to charge the vehicle, meaning that charging can be done using up to 100% green energy. Battery Boost Charging (with SOC cut-off level) and grid charging are also supported.
- Intelligent charging: the operation is capable of prioritizing PV surplus.
- Fast charging: the system can draw energy from both the grid and PV simultaneously for faster charging, and additional Battery Boost Charging can also be used for this purpose.
