High Efficiency × High Power Density |
The all-SiC design delivers a peak conversion efficiency of 99.2% or higher. The control unit, power relays and fuses are highly integrated, achieving a power density of 13.8 kW/L while combining excellent energy efficiency with high space utilization. |
| Versatile Functions | Supports constant-voltage, constant-current and constant-power operating modes, with black-start capability and an integrated MPPT algorithm. Up to 40 units can operate in parallel, allowing system capacity to be expanded as required for diverse applications. |
| Safe and Reliable | Integrates multiple electrical protection functions, including overcurrent, overvoltage, overtemperature and overload protection. Bidirectional short-circuit protection enables microsecond-level fault-current interruption, with short-circuit let-through energy I²t < 1,600 A²s. Certified to IEC 62109, IEC 62477, UL 1741 and other recognized standards, ensuring long-term stable system operation. |
