Efficient Industrial and Commercial Storage Solutions

Tailored for Japan’s High Standards

Japan’s industrial and commercial storage market is at a critical stage of green transformation, known for its “high requirements, high barriers, high standards.” It demands strict response speed, integration, safety, and stability from energy storage devices. Yunneng Technology focuses on large-scale energy storage with a core of “modular products + intelligent management,” relying on comprehensive self-developed 3S technology and extensive experience from numerous flagship projects. Previously, it reached a gigawatt-hour storage supply agreement with local Japanese integrators and successfully entered Japan’s high-threshold industrial and commercial storage market. At this exhibition, it introduced multiple star products, creating a diverse product matrix from cabinet-style to container-style, perfectly matching different storage needs.

Among them, the string-type liquid-cooled energy storage system APstorage 261L stands out with four core advantages, perfectly aligning with local market demands: 1. Compact structure: each cabinet covers only 1.3m², making transportation and installation easier, greatly fitting Japan’s land-intensive scenarios; 2. Highly integrated: each cabinet has a capacity of 261kWh, offering excellent endurance for small to medium-sized industrial and commercial storage needs; 3. Efficient cooling: using advanced liquid cooling temperature control technology, maintaining cell temperature differences within 3°C to ensure safe and stable operation; 4. Flexible expansion: modular design supports parallel expansion, easy to operate and flexible, allowing adjustment of storage scale as needed.

To meet the demands of larger energy storage stations, the exhibition also featured the string-type liquid-cooled energy storage system APstorage 522L and container energy storage system APstorage 2000L, capable of storing approximately 522 and 2000 kWh respectively. These systems help power plants achieve peak shaving, valley filling, demand management, emergency power supply, and grid frequency regulation, effectively reducing electricity costs and improving energy efficiency. With safety, efficiency, and flexibility as key advantages, Yunneng’s products will enable more large-scale energy storage deployments in the future, creating favorable conditions for the internationalization of the APstorage brand and industrial and commercial storage products.

Focusing on Balcony Micro-Light Storage Applications

Building a Convenient Green Energy Ecosystem

Japan’s balcony micro-light storage market is rapidly developing, driven by policy subsidies, high electricity prices, and technological improvements. It is gradually becoming an important growth point for household scenarios, with high requirements for easy installation and quiet operation. In response, Yunneng Technology leverages over 15 years of deep technical expertise and comprehensive strength, focusing on residential and commercial scenarios. It offers two core products: standardized plug-and-play balcony photovoltaic kits and modular free-assembly solutions, including star products like DIY photovoltaic micro-inverter EZ1 and micro hybrid storage inverter EZOG, creating a full green energy loop from power generation, storage, to consumption for local households.

The DIY photovoltaic micro-inverter EZ1 features a plug-and-play connection, allowing grid connection by simply plugging into a power socket, with advantages of easy installation, quick grid connection, and smart operation. It supports Wi-Fi and Bluetooth dual communication modes, making system setup, debugging, and maintenance more convenient, providing intelligent solutions for balcony PV systems. Based on this, the micro hybrid inverter EZOG effectively addresses the intermittency of solar power, enabling both PV generation and energy storage, maximizing utilization. It can operate off-grid without grid connection, greatly meeting users’ needs for off-grid power. The standardized balcony PV kit integrates micro-inverter, modules, and a three-in-one bracket, pre-installed for standardized, modular deployment. It requires no additional assembly—just simple fixing and wiring for quick installation, further improving efficiency and convenience.

Deepening Japan’s Photovoltaic Storage Market

Supporting Green Energy Applications

In the increasingly competitive new energy market, high-quality technical services and localized support have become key competitive advantages. Japan, as a major international new energy market, has strict requirements for the technology, quality, and local adaptation of PV storage products. Relying on years of technological innovation and product accumulation in the field, Yunneng Technology has developed PV storage solutions that combine global leading technology with local adaptability. These solutions provide efficient pathways for regional grid regulation and renewable energy absorption, as well as convenient options for ordinary households to enjoy green electricity.
