- Wide operating range – -40°C ~ +125°C
- Flexible upgrade – local or remote (OTA) firmware update
Designed for System‑Level Intelligence
The TBA-C1500 BCU acts as the secondary master control unit in a hierarchical BMS architecture. It collects data from multiple slave BMUs (like TBA-M16S), performs system‑level protection and balancing, and communicates with inverters, cloud platforms, and user interfaces.
Typical applications: Industrial & commercial ESS (100kWh ~ MWh), high‑voltage residential storage (up to 1500V), and modular battery banks requiring multi‑cluster parallel operation.
Cluster scalability: Supports up to 16 parallel battery clusters with coordinated control.

Why TBA-C1500 is Your Ideal BCU
Real‑time monitoring, remote OTA, cloud‑based security and collaborative balancing.
Parallel control of up to 16 battery clusters – perfect for large C&I projects.
Powerful processor ensures fast response, precise data acquisition, and reliable system coordination.
Seamless System Integration
The TBA-C1500 BCU supports multiple communication protocols (CAN, RS485, RS232, Ethernet, optional wireless) making it compatible with all mainstream inverter brands (SMA, GoodWe, Growatt, Deye, Victron, etc.). Its modular design allows a 2‑level or 3‑level BMS architecture, adapting to projects from small residential systems to large industrial storage farms.
Dry contacts and I/O ports enable external alarm signaling, relay control, and integration with fire safety systems.
