Sunsynk BMS for HV Series Battery System
The Sunsynk BMS (part number SUN-HV-BMS, supplier part number SUNSYNK-BMS-EU) is the battery management system for the Sunsynk high-voltage battery range. It is an essential component — the HV battery system will not operate without a compatible BMS installed. The BMS manages up to 12 Sunsynk HV battery modules per stack, providing centralised monitoring of voltage, temperature, and current with automatic cell balancing, fault detection, and protection against overcharge, deep discharge, and overheating. CAN/RS485 communication for seamless inverter integration. This is a single BMS unit; for complete systems, order as part of a 20.48 kWh (SUN-HV-20.48) or 61.44 kWh (SUN-HV-61.44) configuration. Available from DECO Group, a UK-based solar and energy storage wholesaler for professional trade installers.
