Sunsynk Elite 5.1kWh Battery Storage
- 5.12kWh stackable LiFePO₄ battery module for Sunsynk Elite hybrid inverters, suitable for commercial and residential storage systems.
- Scalable design: stack from a single 5.12kWh battery up to 30.72kWh per Power Distribution Unit for larger backup or self‑consumption projects.
- Outdoor‑ready IP65 enclosure with matching footprint to the Sunsynk Elite base and BMS, for tidy wall or floor‑standing installations.
The Sunsynk Elite 5.1kWh Battery Storage module (SS‑5.1kWh‑ELITE‑BATT‑1P‑IP65‑00) is a 5.12kWh LiFePO₄ stackable battery designed to work with Sunsynk Elite hybrid inverters and the Elite BMS + Base unit. Each module adds 5.12kWh of storage, with up to six batteries per stack for 30.72kWh, making it suitable for small commercial premises, depots and larger homes that want to store surplus solar or provide backup power. The module is supplied in an IP65 enclosure with integrated connections, allowing neat, modular systems that can be expanded as site demands grow.
Key features
- 5.12kWh LiFePO₄ battery module matched to Sunsynk Elite hybrid inverters via dedicated 40–60V DC bus and BMS.
- Stackable from 5.12kWh to 30.72kWh per PDU (up to six modules), so capacity can be increased later without changing inverter hardware.
- IP65‑rated cabinet with compact 720×255×300mm footprint and 55kg weight per module for robust wall or floor installation in plant areas.
- Dedicated Power Distribution Unit and base available to tidy cable management and integrate over‑current protection up to 250A at 1000V DC.
- Designed as part of the Sunsynk Elite ecosystem, supporting neat, vertically stacked layouts alongside 3.6kW, 5kW and 7kW Elite hybrid inverters.
