Hongfa core components solution for HV junction boxes

As the energy storage industry transitions toward 500Ah+ cell capacities and energy densities exceeding 8MWh, the HV junction box has become the system's "nerve center," demanding superior safety and space efficiency. Hongfa addresses these challenges with an integrated core component solution—covering 1000VDC to 2000VDC platforms—that combines fuses, disconnect switches, HV DC relays, and power connectors into a high-performance ecosystem. By leveraging innovations like the HFGD12 module, which integrates disconnect and relay functions to reduce volume by 40%, we strike an essential balance between high-power performance and compact internal design. Our solution provides full-chain coverage from current switching to status monitoring, precisely matching the high-current requirements of next-generation battery systems. This reliability is verified through customized testing, including multi-point short-circuit simulations and current cycling life tests to ensure long-term operational stability. From the 1000A capacity of our HPE509 DC fuses to the high-speed arc-extinguishing technology in our HFUG3V switches, Hongfa is committed to providing the reliable building blocks necessary for a greener and more efficient energy future.
