Australia’s PowerCap enters US with sodium-ion batteries

Australian company PowerCap has officially its sodium-ion battery technology in the US market. Already in use by major enterprises in Australia and introduced in Europe a couple of months ago, the technology is now available to US homes, businesses, and industries.

Initially, the company will expand its presence through distribution channels, with plans to establish local manufacturing lines in the future to scale delivery across North, Central, and South America. A company representative told ESS News that PowerCap’s business model in the Americas will rely on distribution channels controlled by the OEM, supplying approved resellers nationwide. The company recently signed a major US reseller with a presence in 48 states. Once the market, distribution, assembly, reseller, and supply chains are de-risked, PowerCap will consider establishing a cell manufacturing plant in the US, with the location and timing dependent on multiple factors.

Dane El Safty, founder and CEO of PowerCap, described the US launch as “the culmination of years of planning, research, and development.” The timing also coincides with increased US government tariffs, which provides a barrier to entry for Asian manufacturers and gives PowerCap a competitive advantage.

At the European launch in August 2025, Chris Dryden, General Manager of Product Development and Manufacturing, told ESS News that prices are in line with Australia, entering the market at AU$900 (US$ 590) per kilowatt-hour, equivalent to approximately €500 per kilowatt-hour.

The PowerCap POD range has applications across residential, commercial, industrial, grid stabilisation, virtual power plants (VPP), micro-grids and off-grid systems. Certified by TÜV to international standards, the systems feature in-house battery management system (BMS) and energy management system (EMS) technology to ensure performance for over 15 years – covered by a warranty.

The residential storage model comes with scalable capacity from 10.30 kWh to 27.46 kWh, featuring from three to eight battery units in parallel. The product has a cycle life of up to 8000 charge-discharge cycles at 25 degrees Celsius at up to 0.5C rate with an energy retention rate of more than 70%.

The product’s operating temperature range while charging spans from 0 to 55 degrees Celsius, and during discharging from -20 to 60 degrees Celsius. It is IP65 rated and has natural cooling.

The residential product is compatible with the following inverters: Sungrow SH5, GoodWe EH, GoodWe ET 5, Sofar HYD.

PowerCap’s C&I battery is modular from 53.76 kWh to 115.20 kWh, featuring from seven to 15 battery packs. It offers 6000 charge-discharge cycles at 25 degrees Celsius at up to 0.5C rate with the energy retention rate of more than 80% – and 10000 cycles with the energy retention rate of more than 70%.

The product’s operating temperature range while charging spans from 0 to 55 degrees Celsius, and during discharging from -40 to 60 degrees Celsius. It is IP20 rated and features fan cooling.

The commercial battery pairs with DEYE, Sinexcel, GoodWE inverters.

According to PowerCap, all of its products are designed to be 100% recyclable at the end of their service life.
