Boco Electronics' 125KW Energy Storage PCS Module, engineered on a next-generation SiC technology platform, supports a 600V-1000V DC voltage range, delivering 125KW rated output with a sustained 1.1x overload capacity. With 99% peak efficiency, it maximizes power conversion while minimizing energy dissipation. Fully compatible with high-capacity battery systems (280Ah, 314Ah, 320Ah), it integrates advanced cluster-level management to enhance reliability and efficiency. Designed for scalable deployment, its built-in parallel operation capability enables seamless system expansion. Gemini 125H is a bidirectional DCDC converter which is built with buckboost circuit. It can switch between buck and boost mode seamlessly in both direction which brings great benefit for wide voltage operation and flexibly integrated with different battery. The Gemini 125H is built with SiC technology and advanced circuit topology so it has high efficiency and power density which is up to 99.2% and 7.1kW/L. The Gemini 125H has integrated MPPT algorithm and can be easily used in PV system or hybrid ststem.
It can play a key role in energy storage system, DC coupling system, hybrid energy system, etc. The Gemini 125H can help the LPF, Sodium-ion battery, fuel cell system and PV to connect to DC bus easily and flexibly for power and energy extension.
