Sungrow SBR Battery Accessories (V114)

Battery Management System (BMS) — Sungrow SBR Battery Accessories (V114)

The Sungrow SBR Battery Accessories (V114) is a premium battery management system and accessory kit (SBR_S_V114) built around a robust base (AST03129 / AST03744). It monitors and controls modular lithium‑ion storage stacks, providing cell balancing, protective shutdown and flexible communications for commercial and industrial energy storage and PV+storage integrations.

Overview and purpose

This device serves as the central BMS and accessory package for Sungrow SBR modular battery systems. Designed to supervise multi‑module lithium‑ion installations, the SBR Battery Accessories (V114) consolidates safety, monitoring and communications into a single platform to support scalable energy storage projects.

• High‑level BMS for modular battery storage systems (SBR family).
• Monitors and controls up to 16 lithium‑ion storage modules.
• Includes a rugged base platform identified as AST03129 / AST03744.
• Provides cell balancing and protective shutdown functions to maintain safety.

How it works

The SBR BMS continuously measures module voltages, temperatures and state‑of‑charge metrics to coordinate safe charge/discharge behavior across the stack. Built‑in balancing routines and hardware shutdown capability reduce degradation and mitigate fault conditions, while communication interfaces relay status and alarms to higher‑level inverters or energy management systems.

• Active balancing to even cell voltages across modules.
• Protective shutdown logic for over/under voltage and thermal events.
• Centralized monitoring and control for up to 16 modules per BMS unit.
• Flexible communication pathways for integration with inverters, EMS and plant controllers.

Applications and use cases

The V114 BMS and accessory set is intended for modular energy storage deployments where safe, coordinated control of multiple lithium‑ion modules is required. Typical applications include commercial and industrial battery storage, PV‑coupled storage systems, microgrid nodes and other energy storage systems that need scalable module supervision.

• Commercial and industrial (C&I) energy storage systems.
• PV + battery installations requiring integrated BMS control.
• Microgrids and backup power systems with modular battery racks.
• Modular SBR deployments where multiple modules are combined into larger capacity units.
