What is the Powerbox Pro?
- Capacity: 10.24 kWh total (200 Ah at 51.2 V), roughly 9.22 kWh usable at the recommended 90% DoD
- Power: 5.12 kW continuous, 10.24 kW peak, 100 A recommended charge/discharge (0.5C)
- IP65 protection: dust-tight and water-jet resistant — far more siting flexibility than rack batteries
- Cycle life: ≥6,000 cycles (tested at 0.2C, 25°C, 90% DoD), discharge temperature range −20 to 55°C
- Expansion: up to 50 units in parallel covering 10.24–512 kWh (units manufactured after September 2024 only)
The Dyness Powerbox Pro is a 10.24 kWh floor-standing LiFePO4 battery on a 51.2 V system, packing 200 Ah into a single unit. Its defining feature is IP65 protection — dust-tight and resistant to water jets from any direction — which opens up installation locations that rack batteries cannot use. That matters in Phuket, where many homes have no genuinely dry plant room, and it works with the 48 V hybrid inverters we commonly install.
What is the Powerbox Pro, and which homes suit it?
The Powerbox Pro is an all-in-one unit combining cells, BMS and weather-resistant enclosure — unlike rack systems that require multiple modules plus a cabinet. Installation is faster and a single unit provides 10.24 kWh, enough to carry a typical home's essential circuits overnight. Read the power figures carefully: 5.12 kW continuous and 10.24 kW peak. That covers normal household loads, but homes starting several air-conditioners simultaneously or running large pumps should have their true peak demand checked first. Note also that the manufacturer's recommended depth of discharge is 90%, not the 95% some competitors quote, giving roughly 9.22 kWh usable — a figure the datasheet does not state directly but which follows from the recommended DoD. One more caveat: the 50-unit parallel capability (512 kWh) applies only to units manufactured after September 2024, so any later expansion must match production batches.
Highlights from the datasheet
- IP65 protection: dust-tight and water-jet resistant, allowing installation in covered semi-open areas
- 10.24 kWh in one unit: no module assembly or rack cabinet required, faster to install
- 10.24 kW peak power: handles inrush from motor and compressor starts
- ≥6,000 cycles: tested at 0.2C, 25°C and 90% DoD — test conditions clearly stated in the documentation
- Wide −20 to 55°C discharge range: comfortably covers Thai conditions (charging range is 0–55°C)
- Expandable to 512 kWh: up to 50 units in parallel for commercial work (post-September 2024 units)
- Broad inverter support: Solis, Deye, Luxpower, Voltronic, Hoymiles, Growatt, GoodWe, SMA, Victron and others over CAN/RS485

Why this model suits Phuket
- Homes without a dry plant room: IP65 permits installation in a covered garage or semi-open area, which describes many local properties
- Year-round humidity: the sealed enclosure reduces moisture risk compared with open rack batteries
- Storm-season outages: around 9.2 kWh usable carries a home's essential circuits through the night
- Still avoid direct sun and salt spray: IP65 is robust, but on seafront properties we always specify a roofed position away from salt-laden air
Who it suits
- Typical homes wanting overnight backup: 10.24 kWh comfortably covers essential circuits
- Properties without an indoor plant room: needing a battery that tolerates its surroundings
- Jobs prioritising quick installation: a single unit with no assembly or cabinet purchase
- 48 V hybrid systems: using inverters from the manufacturer's supported list
- Installations planning future expansion: up to 50 units on current production versions
Summary
The Dyness Powerbox Pro is a 10.24 kWh, 48 V floor-standing battery whose IP65 rating makes it far more flexible to site than rack alternatives — a good fit for Phuket homes without a sealed plant room. Usable capacity is around 9.2 kWh at the recommended 90% DoD, with 5.12 kW continuous and 10.24 kW peak output. Homes with higher peak demand should consider a higher-current battery such as the BYD LVS 16.0.
