Product Q&A

Q:What is the difference between standalone mode and parallel mode?

Standalone mode uses a secondary architecture (BMU + RBMS). Multi-cluster parallel mode uses a three-level architecture (BMU + RBMS + SBMS).

Q:What voltage levels are available for the RBMS?

Four voltage levels are available: 150V (50-150VDC), 350V (120-350VDC), 750V (260-750VDC), and 900V (500-900VDC).

Q:What is the maximum rated current of the RBMS?

The rated current is optional at 400A or 500A.

Q:How many batteries can be connected in series?

The system supports up to 256 batteries in series.

Q:What communication interfaces does the RBMS provide?

It provides RS485, CAN, Ethernet, and dry contact input/output interfaces for communication with BMU, SBMS, PCS/Inverter/UPS, and monitoring software.
