Sunsynk 5.12kWh Single Battery Unit for HV Series
The Sunsynk 5.12 kWh HV battery (part number SUN-HV-5.12-BATT, supplier part number SUNSYNK-GM5.1) is a single lithium iron phosphate (LiFePO₄) battery module for the Sunsynk high-voltage battery system. Each module provides 5.12 kWh at a nominal voltage of 51.2 V per unit, with a peak discharge capability of 1C (100 A). Modules stack in series using a Sunsynk HV BMS to form high-voltage battery systems up to 61.44 kWh (12 modules). This is a single battery module only; 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.
