Hoymiles Announces the HiBattery 4020 Series at Munich’s “Unbreakable Night” Event

On 22 June 2026, Hoymiles Power Electronics Inc. staged a high‑profile launch in Munich, unveiling its new HiBattery 4020 X plug‑in home battery. The event, branded “Unbreakable Night,” highlighted the company’s commitment to safety, reliability, and expanding its portfolio of energy‑storage solutions for residential and commercial markets.

A New Generation of Home Energy Storage

The HiBattery 4020 X is Hoymiles’ first hybrid model that can be coupled directly to photovoltaic (PV) modules. Key technical specifications include:

  • PV input capacity: Up to 4 000 W, distributed across four independent MPPT channels.
  • Scalability: Stackable, cable‑free modules that enable expansion from a 4 kWh baseline to a 16 kWh configuration.
  • Efficiency: A 96.5 % DC‑to‑AC conversion rate, ensuring that most of the stored energy is usable by household appliances.

The series also offers an AC‑coupled variant, the HiBattery 4020 AC, which can be retrofitted into existing solar installations to provide storage without modifying the PV array itself.

Emphasizing Safety and Reliability

Hoymiles positioned the HiBattery 4020 Series as “unbreakable” in both performance and safety. The product incorporates automotive‑grade components and rigorous testing protocols to mitigate risks such as thermal runaway or short circuits—common concerns in residential battery systems. The company’s focus on robust safety measures is intended to give homeowners peace of mind while enjoying the benefits of renewable energy storage.

Strategic Partnerships and Market Reach

During the launch, Hoymiles underscored the strength of its partnerships across Europe, citing collaborations with more than 180 industry leaders, distributors, and key stakeholders. These alliances aim to accelerate the adoption of the HiBattery 4020 Series in diverse market segments, from rooftop installations to balcony‑mounted systems, and to facilitate seamless integration with existing solar arrays.

Corporate Context

Hoymiles, listed on the Shanghai Stock Exchange, has consistently pursued innovations in plug‑in energy storage. With a market capitalization of roughly 10.9 billion CNY and a stock price that recently hovered around 87.70 CNY (as of 21 June 2026), the company has positioned itself as a significant player in China’s renewable‑energy infrastructure sector. The introduction of the HiBattery 4020 Series is expected to enhance its product portfolio, potentially influencing investor sentiment and expanding its footprint beyond China into European markets.

Outlook

The launch event in Munich signals Hoymiles’ intent to compete in the rapidly growing residential battery market. By combining high efficiency, modular scalability, and stringent safety features, the HiBattery 4020 Series could become a compelling option for homeowners seeking reliable, plug‑in storage solutions that integrate seamlessly with existing solar PV systems. As the company leverages its established partnerships and technological expertise, the HiBattery 4020 Series may drive further growth and solidify Hoymiles’ standing as a key contributor to the global transition toward sustainable energy storage.
