Swedish heat pump manufacturer Aira unveils a new battery energy storage system and inverter range for the residential market. Aira Power Hub inverters and Aira Power Store batteries are being marketed as part of a whole home energy management system, initially launched in the UK and Italy, followed by a German rollout.
Swedish heat pump manufacturer Aira has launched a range of batteries and inverters for homes as the company looks to position itself as a provider of whole-home energy management. The new Aira Power range consists of Aira Power Store, a scalable household battery system, and Aira Power Hub, an inverter brand available in single-phase and three-phase variants.
Aira Power Store is a modular lithium iron phosphate battery with a stackable capacity from 7 kWh to 20 kWh. The system can operate with two to six modules in series, with four racks in parallel.
Dimensions for the residential battery range from 30″ x 30″ x 6″ for a two-module installation to 30″ x 70″ x 6″ for the six-module system. Charging and discharging power ranges from 5.94 kW at entry level to a maximum of 17.82 kW when 20 kWh of storage is installed. System weight starts at 86.6 kg for the two-module system, increasing by 34 kg per module up to a maximum of 222.3 kg for a six-module unit.
Aira Power Hub is a transformerless inverter available in single-phase variants of 7 kW and three-phase variants of 15 kW. Both models are equipped with maximum power point trackers with a voltage range of 100 V to 720 V and a maximum current of 14 A, and have a DC to AC efficiency of 98%. The single-phase model has a rated AC power of 7.36 kVA and a rated AC voltage of 230 VAC. The Aira three-phase inverter has a nominal AC power of 15 kVA and an AC voltage of 400 V.
Aira Power Hub inverters have an IP-65 rated enclosure, an operating temperature of -20 C to 60 C, weigh 21 kg and have a maximum operating altitude of 2,000 m. The inverters and battery storage products are offered with a 10-year warranty.
Both products are positioned as part of Aira’s broader home energy systems proposition, which includes the company’s flagship heat pump product and AI-powered energy management system Aira Intelligence.
The launch of Aira’s Power range completes the Swedish company’s ambition to roll out a complete energy management system for domestic use. Speak with pv magazine in February 2025, Kaj af Kleen, head of product and technology, said that a key reason for developing an inverter instead of using a third-party product was to have full access to important data.
“The reason we do this is because – it’s the same logic as for the heat pump – if you want to do something really well, you need to have access to all the controls, all the sensors and the firmware,” says Af Kleen. “That requires iterative development, where engineers sit together and do the real work, and that is best done together in one room, not across the ocean.”
In a press release ahead of the launch, Aira Group CEO Peter Prem said the inverter and battery storage products represent a “major milestone” for the company.
“By expanding our vertically integrated model to home energy, we are giving households the tools to efficiently generate, store and manage clean energy.”
The first Aira Power installations are expected in January 2026 in the UK and Italy, followed by a launch in Germany.
