BMS for Sunsynk HV Series
BMS for Sunsynk HV Series
Sunsynk HV series racks and BMS — Cabinet to suit the system, and a BMS that is normally bought with it.
A Sunsynk HV battery system is modules in a cabinet with a BMS managing them, and these are the parts around the modules.
About the Sunsynk HV series racks and BMS
The cabinets come with doors and are sized to the system rather than counted in rack units: one for the 20.48 kWh system and one for the 61.44 kWh. Ordering by capacity rather than by module count is the way round to think about it.
The BMS is listed as a singular part for service purposes. In practice it is bought as part of the SUN-HV-20.48 or SUN-HV-61.44 system, which is the route to take unless a replacement is specifically needed.
What does this fit?
This is the cabinet and management unit a Sunsynk HV battery system is built in.
The cabinets are sized to the system: one for the 20.48 kWh HV system and one for the 61.44 kWh. The BMS is a single part and is normally bought as part of the SUN-HV-20.48 or SUN-HV-61.44 system rather than on its own.

What the job needs
The details that decide whether this suits the system:
- The 20.48 kWh cabinet and the 61.44 kWh rack are sized to their systems — check the system capacity, not the module count.
- Both come with a door.
- The BMS is a singular part. Use SUN-HV-20.48 or SUN-HV-61.44 for a complete system rather than ordering the BMS alone.
Where this earns its place
The part is chosen by the size of the HV system.
Things worth knowing about this listing
