Dyness PowerBox Pro 10.24kWh LiFePO4 Battery
A low-voltage LiFePO4 battery with 10.24kWh nominal capacity, integrated battery management and IP65 protection. It supports wall-mounted or floor-standing installation for residential solar storage.
Key Features
- Practical storage: 10.24kWh nominal energy, with approximately 9.22kWh usable at the recommended 90% depth of discharge.
- Flexible installation: Wall-mounted or floor-standing installation with IP65 protection.
- Battery management: Integrated BMS supports cell balancing and protection against abnormal voltage, current and temperature.
- Inverter communication: CAN and RS485 for compatible low-voltage inverters.
- Cycle life: At least 6,000 cycles under the manufacturer’s stated test conditions.
- Expandable system: Parallel expansion is available, with the supported number of units dependent on the approved configuration. See the expansion details below.
Where to Use
Residential solar self-consumption, off-grid and backup systems with a compatible low-voltage inverter. The inverter and system design determine backup capability and available output power.

Additional Details
- Expansion configuration: Dyness’s current product page and datasheet state up to 50 units, while its August 2026 user manual specifies 10. Contact Energian to confirm the battery hardware, firmware and inverter combination before designing a system above 10 units.
- Use an approved inverter model and the correct communication settings. Expansion requires compatible battery hardware and firmware, correctly sized cables, isolation and protection, and installation in accordance with the user manual.
- Warranty conditions: The linked European warranty specifies 10 years with inverter communication; operation without communication has a 3-year term. Capacity cover is subject to the stated time and energy-throughput limits.
- For inverter compatibility, battery sizing or installation advice, call 020 8064 0335 or email info@energian.co.uk.
Delivery is normally available within 2–3 working days across the UK. Longer delivery times may apply to the Scottish Highlands, islands and Northern Ireland.
