Overview
SM-STACK was designed for the service technician, not the showroom. Modules slide onto a single base, share one BMS and one CAN bus, and can be added a year later without replacing the cabinet.
Terminals, breaker and communications are all reachable from the front, so a stack installed in a 600 mm service corridor remains maintainable. The cabinet is 178 mm deep and can be floor-standing or rack-mounted.
Each module carries a serialised test report: capacity, internal resistance and insulation value at the time of assembly.
Highlights
- Stack one to five modules on a single base
- Front-access terminals, breaker and DIP switches
- Active balancing with 200 ms fault logging
- Preloaded with 30+ inverter protocols
