The TBCU series residential energy storage high-voltage parallel module consists of a DC/DC bidirectional converter and a Battery Management System (BMS). The module uses dual-chip digital control, allowing a single low-voltage lithium battery module to be stepped up to the bus high voltage, enabling direct parallel connection on the high-voltage side. The system is compatible with mainstream high-voltage hybrid inverters and offers advantages such as a bidirectional wide voltage range, bidirectional voltage and current active control, high conversion efficiency, real-time battery status monitoring, multi-module parallel operation, and natural cooling.
