Introducing ReafCoreX: The Future of Home Battery Solutions

In a strategic move aimed at enhancing energy efficiency and reliability in homes, Remix Point Co., Ltd. (stock code: 3825), headquartered in the Minato ward of Tokyo, has announced the launch of its innovative home battery system, ReafCoreX. Set to commence sales in August 2026 through a network of partners across Japan, this cutting-edge product has recently received the JET certification from the Japan Electrical Safety & Environment Technology Laboratories, ensuring compliance with safety and performance standards.

Understanding the Market Dynamics

The announcement comes at a pivotal time when the demand for residential energy storage solutions is on the rise. Factors such as soaring electricity costs and an increased emphasis on disaster preparedness are driving this trend. With Japan's energy landscape evolving, the introduction of new energy-saving housing standards—GX ZEH—is expected to further accelerate the growth of the residential battery market by 2027. Urban areas, particularly, are witnessing a surge in demand for compact, space-efficient battery systems, prompting Remix Point to respond with the slim profile of the ReafCoreX, measuring only 150mm in depth.

Key Features of ReafCoreX

1. Space-Saving Design

ReafCoreX boasts an incredibly compact design, making it suitable for tight spaces. The battery can be installed in outdoor dead zones or along property lines without traditional space requirements becoming an obstacle. This flexibility is particularly beneficial for urban dwellers who may have struggled with installation due to spatial constraints.

2. Diverse System Configurations

Consumers can customize their energy systems according to their specific power consumption needs and budget. The ReafCoreX supports up to four battery units, each with a capacity of 4.9kWh, allowing for configurations ranging from 4.9kWh to 19.8kWh.

3. Cold-Weather Performance

Designed to function optimally in extreme temperatures, ReafCoreX can operate in conditions as low as -30°C to as high as 53°C, which qualifies it for use in various climatic zones, including snowy regions.

4. Flexible Operation Modes

ReafCoreX comes equipped with five operation modes, enabling users to optimize electricity costs and prepare for power outages. This adaptability allows homeowners to tailor the system according to their lifestyle and energy needs.

Achieving JET Certification

Recently, the 5.9kW series of ReafCoreX obtained JET certification, which streamlines the performance testing process for grid connection. This certification not only enhances the product's credibility but also significantly shortens the time required for grid collaboration discussions with utility providers, thus enabling quicker installation.

Future Outlook

With the impending introduction of low-voltage resources into demand-supply balancing markets starting April 2026, the ReafCoreX is positioned to support bi-directional discharge capabilities. This functionality will facilitate its integration into future demand response (DR) and virtual power plant (VPP) systems, enhancing its role in the evolving electricity market. The launch of the ReafCoreX is seen as a critical first step in Remix Point's initiative to develop a comprehensive energy management service tailored for residential consumers.
