Sigenergy 25kW Bi-Directional DC EV Charger (EVDC 25)
SKU SIG-EVDC-25-CHARGER
The Sigenergy SigenStor EVDC 1 is a 25kW bi-directional DC charging module engineered to serve as the central energy bridge between electric vehicles, solar generation, battery storage, and the electric grid. This advanced DC-coupled system delivers up to 25kW charging power and 25kW discharge capability, enabling rapid EV charging with approximately 150 km of driving range added per hour while simultaneously supporting Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) applications.
The unit features dual connector compatibility with CCS1 and NACS (Tesla) standards, operating across 150-1000V output voltage range with 80A maximum current capacity. By leveraging DC-coupled architecture, the system allows electric vehicles to charge directly from solar-generated electricity without multiple conversion losses, achieving 100% green power charging efficiency while providing virtual grid capacity expansion through intelligent bidirectional power flow.
SigenStor EVDC Module Features
- Rapid DC Charging: 25kW charging capacity delivers approximately 150 km driving range per hour, significantly faster than Level 2 AC charging solutions
- Vehicle-to-Home Backup: V2H capability transforms EV batteries into emergency backup power sources, providing 100+ kWh storage capacity when combined with Sigenergy battery systems
- 100% Green Charging: DC-coupled architecture enables direct solar-to-vehicle charging without AC conversion losses, maximizing renewable energy utilization
- Grid Services Revenue: V2G functionality allows EV battery capacity to participate in peak shaving, load balancing, and demand response programs for energy cost optimization
- Outdoor-Rated Durability: IP66/NEMA 4X enclosure with filterless smart air cooling eliminates maintenance while providing complete dust and water ingress protection
Adaptable to All Your Charging Needs
The SigenStor EVDC 1 delivers intelligent charging optimization through multiple operational modes tailored to specific energy scenarios and user priorities.
- Maximum Power Rapid Charging: Delivers full 25kW charging capacity by intelligently drawing power from solar generation, grid connection, and battery storage simultaneously for fastest possible charging times
- Surplus PV Priority Charging: Automatically charges EVs with excess solar production while maintaining configurable priority ranking between EV charging and home electrical loads for maximum self-consumption
- Battery-Boosted Charging: Leverages battery storage to supplement EV charging power beyond available solar and grid capacity, with intelligent state-of-charge management to prevent excessive battery depletion
Sigenergy 25kW Bi-Directional DC EV Charger Technical Review
The SigenStor EVDC 1 EV charging module shines through its implementation of true bi-directional power flow at 25kW capacity. Unlike conventional AC Level 2 chargers limited to 7-12kW single-phase or 19.2kW three-phase operation, the DC-coupled architecture delivers power directly to EV battery packs at their native DC voltage, eliminating onboard charger bottlenecks and conversion losses. The 150-1000V output voltage range accommodates both legacy 400V battery architectures and emerging 800V ultra-fast charging platforms used in premium EV models, while the 80A current limit ensures compatibility with vehicle-side charging standards.
Vehicle-to-Home functionality transforms EV battery packs into mobile distributed energy resources, with typical 75-100 kWh vehicle batteries providing multi-day backup power when combined with intelligent load management. Vehicle-to-Grid capability enables participation in utility demand response programs, peak shaving applications, and frequency regulation services, generating revenue streams while supporting grid stability during high-demand period
