xPylontech Force FH2 BMS Controller FC0500M-40S-FH (BMU) With Base and Cables
What this controller is used for
The FC0500M-40S-FH (also commonly listed as FC0500M-40S-FH2 / FC0500M-40S-V2 depending on kit version) is the Battery Management Unit (BMU) for the Pylontech Force H2 high voltage lithium iron phosphate (LiFePO4) battery system. It sits on top of the stack and is essential for:
- Monitoring and protection of the battery tower (voltage, current, temperature, faults).
- Communication between the battery tower and the inverter via CAN or RS485.
- System start-up and control (start button, status LEDs, internal relay control depending on inverter handshake).
- Parallel operation when using multiple Force H2 towers (Link ports are used to daisy chain towers so one becomes the “master” string)
How many Force H2 batteries it can control in one stack
For the Force H2 system, one BMU is used per tower. A single tower is typically built with 2 to 4 Force H2 battery modules in series (each module is 96V, so the tower voltage becomes 192V, 288V, or 384V).
Important note: Many Force H2 installations require a minimum of 2 modules per tower (not 1). Some online listings mention higher counts, but the Force H2 documentation and common distributor specifications describe the standard tower configuration as 2 to 4 modules per BMU.
What is included
Each controller set includes the items required to build a tower head and complete the essential connections:
- BMU controller (FC0500M-40S-FH)
- Base for the Force H2 stack
- Power cables (to connect the tower to the inverter)
- Communication cables (CAN / RS485 depending on inverter integration)
Why you need it
- Mandatory for a working Force H2 tower, the system will not operate correctly without the BMU managing the stack and providing inverter communications.
- Cleaner installation with dedicated ports for power and comms, plus link ports for multi tower system set up.
- Designed specifically for Force H2, ensuring correct voltage level operation and protection strategy for high voltage storage.
Typical system design guidance
- 1 BMU per tower
- 2 to 4 Force H2 battery modules per tower
- Multiple towers can be operated in parallel in larger systems (with correct wiring, communications linking, and, where required, a suitable combiner solution).
