Aetom to Supply "Ultra-Slim Matrix Transformers" for North American Solar and ESS Markets in Partnership with Hanwha Solutions

KOSDAQ-listed Aetom is joining forces with Hanwha Solutions to develop power components targeting the North American solar and energy storage system (ESS) market. By expanding its business scope from electric vehicles and artificial intelligence (AI) data centers to renewable energy, Aetom aims to establish its high-value power component business as a new growth pillar.

On August 27, Aetom announced that following the initiation of a new partnership with Hanwha Solutions in June, it is now developing transformers and inductors for ESS and solar microinverters destined for the North American market.

The core of this project is the application of Aetom's proprietary ultra-slim matrix transformer technology in Hanwha Q CELLS’ North American market products, a solar business subsidiary of Hanwha Solutions.

The products under development by Aetom mainly consist of power components for medium-to-large-scale ESS targeting North America and for solar microinverters. In the ESS segment, Aetom is submitting matrix-type transformer and inductor designs and advancing development. For microinverters, the company is pursuing the development of high-output transformers.

In particular, Aetom plans to adopt its ultra-slim matrix technology, reducing transformer height to as low as 30 mm. Since inverters for solar and ESS applications must handle high-output power for long periods, it is essential to reduce power loss and heat, while also ensuring components fit within limited spaces.

According to the company, utilizing a matrix structure helps reduce the size of power components while enhancing heat dissipation and space efficiency. Through this technology, Aetom aims to address the demand for compactness and lighter weight in ESS and microinverters and ensure reliable power conversion in high-output environments.

If mass production follows, Aetom expects to see a significant mid- to long-term increase in sales. The company is scheduled to begin supplying product samples starting in September. After product verification and customer evaluation, and if the process proceeds smoothly, mass production and supply are targeted for 2028.

A company official stated, "Given the high demand for mass production in this product group, if supply is fully ramped up after development and verification, we expect to secure stable, high-volume manufacturing orders."

This collaboration is also notable in that Aetom’s business portfolio is expanding from a primary focus on electric vehicles to also include AI data centers and renewable energy.

In the electric vehicle sector, Aetom has registered as a first-tier supplier and secured orders from Hyundai Mobis and is also developing an ultra-slim planar transformer for electric vehicle integrated charging control units (ICCU) with LS Automotive. With Harbinger Motors in the United States, Aetom is working on the development of a 22-kilowatt class product for commercial EVs.

In the AI data center sector as well, the company is expanding its power components business for high-output power supply devices. Through this partnership with Hanwha Solutions, Aetom is also entering the North American solar and ESS market, further broadening its business portfolio focused on high-output, high-efficiency power components.

The North American renewable energy market, in particular, is expected to serve as a new growth opportunity for Aetom as demand for ESS increases along with the expansion of solar power generation. If their power components are adopted by customer products, this could lead to prolonged, recurring mass production orders, going beyond one-time development projects.

However, the company cautioned that the current initiative is in the development stage, and whether and to what extent it generates sales will depend on the future sample supply, customer evaluations, product verification, and mass production approval.

Ha Taeksoo, CEO of Aetom, commented, "Participation in Hanwha Solutions’ development is a critical milestone for expanding Aetom’s ultra-slim, high-efficiency power component technologies into the renewable energy sector. We will proceed with the development and verification of our ESS and microinverter products as planned to secure a stable mass production supply base in the North American renewable energy market."
