The Story
The Sunsynk 61.44kWh HV Battery System is a high-voltage modular lithium ferro-phosphate (LiFePO₄) energy storage solution comprising 12 x 5.12kWh battery modules, a dedicated BMS and rack enclosure for large-scale commercial and industrial applications.
Product Description
This complete rack-mounted system delivers 61.44kWh of nominal storage capacity at high voltage (538–691V), designed for integration with Sunsynk high-voltage hybrid inverters in commercial solar, grid backup and peak-shaving installations. The modular 19″ rack format allows straightforward scaling and maintenance, with full 100% depth of discharge capability and 1C charge/discharge rates.
Key Features
- High-voltage operation: 538–691V working range reduces cabling losses and enables direct coupling with high-voltage inverters.
- Full modular scalability: 12 x 5.12kWh modules in series provide 61.44kWh total capacity in a single rack.
- High power capability: 100A max continuous charge/discharge (61.44kW at 1C) for demanding commercial loads.
- Advanced BMS: Integrated battery management system with cell balancing, thermal protection and communication protocols.
- 100% DoD: Full depth of discharge maximises usable energy without accelerated degradation.
- Long cycle life: LiFePO₄ chemistry with >6000 cycles at high DoD, 10-year warranty when paired with Sunsynk inverters.
Technical Details
- System capacity: 61.44kWh nominal (12 x 5.12kWh modules).
- Battery chemistry: Lithium ferro-phosphate (LiFePO₄).
- Working voltage: 538–691V DC.
- Max charge/discharge current: 100A continuous (1C rate).
- Module capacity: 100Ah per module.
- Depth of discharge: 100%.
- Operating temperature: Charge 0–55°C, discharge −20–55°C.
- System part number: SUN-HV-61.44.
- Components included: 12 x SUN-HV-5.12-BATT modules, 1 x SUN-HV-BMS, 1 x SUN-HV-61.44-BATTRACK-DOOR rack.
Physical Specifications
