Product Overview
The Sunsynk 5.12kWh HV Rack-Mount Lithium Battery Module is an individual energy-storage module for the Sunsynk high-voltage rack system. Each module provides 5.12kWh of nominal storage at 51.2V and 100Ah. Twelve modules connected in series form the 61.44kWh bank, used with the dedicated BMU and rack.
Key Features
- 5.12kWh nominal energy per module allows the specified HV system to be assembled from individual components.
- Lithium iron phosphate chemistry, identified as LiFePO4 or LFP in the manufacturer documentation.
- 51.2V nominal module voltage and 100Ah capacity.
- Rack-mount format suits the dedicated Sunsynk HV battery rack.
- Separate positive, negative and BCOM communication connections follow the manufacturer system layout.
Applications
- Assembly of a Sunsynk 61.44kWh high-voltage battery bank.
- Replacement module in the specified HV rack system after installer assessment.
- Planned expansion of a compatible Sunsynk HV bank where the inverter voltage range and manufacturer requirements permit.
Why Choose This Product?
This module is the individual storage component used in the Sunsynk 61.44kWh HV rack system. It supports component-level procurement while retaining the battery type and connection arrangement specified for that system.
Important Notes
- Price is for one 5.12kWh battery module. BMU, rack, inverter and external cabling are separate items.
- The 61.44kWh bank requires twelve modules in series, one SUN-61.44-HV-BMS control unit and one BATTRACK-SUN-61.44-HV rack.
- This is a module for an HV battery system. Its 51.2V module rating does not establish compatibility with a standalone 48V inverter or other Sunsynk battery ranges.
- Any smaller bank or later expansion requires installer verification of inverter voltage limits, module generation, firmware and battery condition. Follow the manual's state-of-charge matching procedure before adding modules.
- Indoor installation only. Installation, replacement and commissioning must be completed by qualified personnel in accordance with the manufacturer manual.
