Hoymiles Unveils the New HiBattery 4020 at The Unbreakable Night Event in Munich

On June 22, 2026, Hoymiles made a significant splash in the renewable energy sector by unveiling its latest innovation, the HiBattery 4020 series, during an extraordinary event titled 'The Unbreakable Night' in Munich, Germany. This event gathered over 180 industry leaders, distributors, and stakeholders, all eager to witness firsthand the technological advancements embodied in the new plug-in home battery.

The HiBattery 4020 represents a leap forward in home energy storage solutions, boasting two configurations: the HiBattery 4020 X and HiBattery 4020 AC. The X model is notable for its hybrid capabilities, connecting directly to photovoltaic (PV) panels, with support for PV inputs up to 4,000 watts across four independent Maximum Power Point Tracking (MPPT) channels. This makes it ideal for complex roof and balcony installations, further enhancing the versatility of residential solar setups.

Meanwhile, the AC version is engineered for seamless integration with existing solar systems. It provides homeowners with an immediate boost in energy storage capacity without the need for extensive reconfiguration of their current systems, allowing for greater efficiency and functionality.

One of the standout features of the HiBattery 4020 series is its commitment to performance. The modular design allows for stackable units, enabling energy capacities to expand from 4 kWh to 16 kWh. It achieves a high efficiency rate of 96.5% for both DC and AC power, ensuring reliable energy supply for essential household appliances.

Safety is paramount in today’s energy storage solutions, and the HiBattery 4020 does not disappoint. It utilizes automobile-grade LiFePO4 battery cells, a sophisticated Battery Management System (BMS), and even includes aerosol fire suppression technology alongside an IP66 rating for dust and waterproofing. These elements collectively ensure maximum reliability in diverse environmental conditions, offering users peace of mind.

Artificial intelligence is integrated into the series, elevating its intelligence to optimize energy consumption in real time based on dynamic pricing models. The Energy Ledger control panel allows users to monitor costs and consumption patterns transparently, further reinforcing Hoymiles' commitment to innovative and sustainable energy solutions.

During the event, the HiBattery 4020 series was honored with the prestigious EUPD Innovation Award. Markus A.W. Hoehner, CEO of EUPD Research, presented the award, highlighting the product's exceptional safety credentials and innovative design. The recognition reflects Hoymiles' unwavering dedication to advancing home energy solutions.

The event concluded with the launch of the 'Unbreakable Alliance,' aimed at fostering partnerships with 25 pivotal European customers and solidifying Hoymiles' long-term commitment to collective success in the energy sector. Dr. Yang Bo, CEO of Hoymiles, emphasized: "The HiBattery 4020 series marks a vital step from our leadership in micro-inverters to comprehensive home energy solutions. Our goal is to deliver safe and reliable products, providing genuine peace of mind for European households."

As Europe transitions toward a decentralized energy future, Hoymiles reaffirms its dedication to safe and dependable solar energy storage solutions, resonating with the theme of 'The Unbreakable Night.' The HiBattery 4020 X and AC models present exciting new possibilities for environmentally conscious homeowners looking to maximize their energy independence.
