KEY FEATURES

PURPOSE-BUILT FOR BESS

The SBS Stationary delivers grid-grade battery management with 1500 V native design, Ethernet connectivity, and always-on optimization for utility-scale energy storage.

1500 V PURPOSE-BUILT

1500 V rating with 6000 V withstand. HV-based voltage measurement (not GND-based). >100 MΩ leakage isolation supports up to 100 parallel strings.

ETHERNET-CONNECTED

Dual-pair 100BASE-TX Ethernet for EMS integration. 3x CAN FD at 5 Mbit/s. Future single-pair 100BASE-T1 support planned.

ALWAYS-ON OPTIMIZATION

Low-power standby for idle grid periods. Optimized for always-on duty cycles in stationary energy storage deployments.

SOFTWARE & PLATFORM

BARCELONA PLATFORM

The SBS Stationary is the grid-optimized member of ME's 3rd-generation Barcelona BMS platform, sharing a common architecture and software stack with SBS Core, SBS High, and BMDU. All SBS controllers support multistring configurations.

All four Barcelona variants run the identical SBS Software Platform. One software image supports every variant, switchable at runtime via the Configuration Framework. This means SBS Core benefits from the same validated, ASIL D ready codebase with 14-day release cadence.

Compatible with CMBXX cell monitoring board family, supporting arrays of over 500 cells per controller over 1500V-isolated isoSPI.

ONE BINARY, ALL VARIANTS
Same software image runs on SBS Core, SBS High, BMDU, and SBS Stationary. Configuration Framework switches behavior at runtime.
14-DAY RELEASES
Continuous integration with bi-weekly validated releases. Faster iteration, faster time to production.
INDUSTRIAL CERTIFICATION PATH
ISO 26262 + IEC 61508 functional safety. EU Cyber Resilience Act (CRA) compliance planned for 2027.

BARCELONA PLATFORM FAMILY

SBS CORE

Compact controller, side connectors, external shunt

SBS HIGH

Full-featured controller, integrated shunt, 7 contactor drivers

BMDU

Integrated controller + power distribution with circuit breaker

SBS STATIONARY

1500V BESS-optimized with Ethernet

SHARED SOFTWARE: All four variants run the same C++ software stack. One codebase, one safety case, one release cadence. All variants support multistring configurations.
