China’s Nebula Electronics Co., Ltd., Germany’s ambibox GmbH, and Australia’s Red Earth Energy Storage Ltd. today announced a global strategic partnership to jointly develop the world’s first residential “Microgrid-in-a-Box” (MIB) solution. The MIB is an integrated hardware and energy management system that combines solar, storage, bidirectional EV charging.
This partnership spans Asia, Europe, and Oceania, and aims to connect the convergence of distributed energy with the electric mobility market. The MIB will redefine the future energy grid by enhancing the local utilisation of renewable energy and supporting grid stability at the same time.
The collaboration builds scalable and affordable energy management and distribution systems that seamlessly integrate both V2H (Vehicle-to-Home) and V2G (Vehicle-to-Grid) functionalities, reducing the size or need for a home battery. Real-world testing shows that this can reduce overall energy costs for users by up to 60%, while generate revenue for homeowners who are providing grid services through market participation and trading, resulting in zero energy cost for households.
The partnership will leverage each party’s core competencies in technology innovation, industrial manufacturing, and localised market operations. Besides that, the agreement will support each of the company’s expertise for the joint product development:
ambibox GmbH will provide its commercially proven power electronics and energy management technologies, already validated in European markets with ambibox granted patents for the MIB.
Nebula Electronics will take charge of integrating and mass-producing power electronics and battery systems, drawing on its strong R&D and manufacturing capabilities.
Red Earth Energy Storage will contribute its expertise in off-grid energy systems, cloud-based platforms, and end-user applications to accelerate deployment in Australia and New Zealand.
“This is more than a technical alliance—it’s a cross-cultural, cross-market innovation model,” said the Nebula Electronics project lead. “This groundbreaking partnership not only ushers in a new era of commercial V2G applications but also offers critical support for global energy transition and carbon neutrality goals. Centered on the concept of “local manufacturing + global coordination, this tri-national alliance is laying the foundation for a smarter, more efficient, and sustainable energy future.”
Manfred Przybilla, CEO of ambibox, said “ambibox has been working on the Microgrid-in-Box for almost a decade. With EVs that are V2G ready to be used as a battery on wheels, we are ready to deploy the technology into the markets. We’ve demonstrated our experience in the field with the launch of over 200 commercial V2G pilot projects in Sweden, validating the system’s reliability under demanding conditions.”
Marc Sheldon, CEO of Red Earth Energy Storage said, “The partnership with ambibox and Nebula Electronics will deliver new opportunities for households to realise their potential to be truly energy independent. Using their electric vehicle as a battery means they can use the energy on their vehicles to power their home instead of relying solely on a home battery or grid electricity.”
The first batch of jointly developed products is expected to enter the markets of China, Europe, and Australia/New Zealand in 2026, with plans to expand to other regions.
About RedEarth
Headquartered in Darra, Queensland, RedEarth has developed energy storage systems and an energy management platform for both on and off-grid customers in the residential, commercial, and industrial sectors. We are dedicated to producing high-quality solutions that are versatile, scalable and built to customers’ specifications and expandable to suit their needs for more electricity over time.
Over 10,000 RedEarth systems and batteries have been deployed since the company was founded in 2013. Our vision is for businesses and households to sustainably generate more clean energy than they can consume, enabling them to sell their excess electricity to the grid or for it to be traded between individuals at prices commensurate for contributing to Australia’s growing electricity needs.
We’re creating a positive impact by expanding the growth of renewable energy to decarbonise the grid. Through distributed storage, RedEarth expands the capacity for renewable energy generated to be seamlessly added to the grid to deliver greater value to our customers, to help the grid, to benefit the environment and to contribute to the greater good of Australia.
