On April 1, the 14th International Energy Storage Summit and Exhibition (ESIE 2026) opened in Beijing. With the theme of “controlling the network without boundaries and intelligent matching panorama”, he mai made a blockbuster appearance with the latest technological achievements. two new strategic products, 460kW high-flexibility serial PCS and 1725kW strong-structure network PCS, were launched, fully demonstrating its technological breakthrough and systematization capability in energy storage system.
from” equipment supply “to” system value “
Wo Mai completes strategic transition
Today, the energy storage industry is accelerating into a new stage with” system value “as the core. Relying on 14 years of profound accumulation of power electronics technology and global layout, He Mai has completed a comprehensive leap from micro-inverter to complete optical storage system, from single-point equipment to system capability, from product competition to system and service competition.
At present, the company has established a global operation system, set up 5 regional headquarters, 4 manufacturing bases and more than 20 local support centers, forming a complete product matrix covering DIY, household use, industry and commerce, large ground power stations and other diversified optical storage scenarios, smart optical storage solutions have served millions of users in more than 190 countries and regions around the world .
at the exhibition site, yang bo, president of wo mai, delivered a speech: “at present, the energy storage industry is accelerating from policy-driven to market-oriented value creation, from scale expansion to high-quality development, this trend is also the direction of the strategic layout of the company. We have transformed from a global leader in micro inverters to a comprehensive optical storage solution provider . For the new power system, energy storage competition is no longer limited to a single device, but upgraded to a full scenario solution, full life cycle value and the whole industry chain synergy capacity of the comprehensive competition. Based on this judgment, He Mai continues to increase R & D investment and global layout, from technology, products to ecological comprehensive upgrade. The two new energy storage products released at this exhibition are a positive response to industry trends.”
the next stop of energy storage
the two new products are jointly launched
as the energy storage industry moves towards a new stage of large-scale, long-term and multi-scenario application, the limitations of the traditional PCS scheme are increasingly prominent. The two new products released this time, directly hit the industry pain points, with “panoramic adaptation” and “hard core network” as the core, for the energy storage system to bring the value of the whole life cycle.
460kW highly flexible serial PCS
aiming at the problems of single point failure affecting the whole station, rigid capacity expansion and complex operation and maintenance in the traditional scheme, wemai 460kW serial PCS provides innovative power conversion solutions with excellent system compatibility, it can seamlessly adapt the two mainstream system forms of the group string-type variable flow boost all-in-one machine and the integration of AC-DC.
advanced liquid cooling technology enables the product to operate without load reduction at 60 ℃ water temperature, the internal temperature difference of the module is strictly controlled within 2 ℃, and the service life of the core device is prolonged by more than 20%. The equipment itself uses a three-level topology plus a hybrid silicon carbide module, with a full-load charge and discharge efficiency of more than 98.5 percent, a peak value of more than 99 percent, and an annualized revenue increase of 1.5 percent .
1725kW strong network PCS
challenges brought by high proportion of new energy access to the power grid, he Mai 1725kW network PCS takes the stable network as the core, relying on six core capabilities to achieve system-level stability support.
The liquid cooling design enables the new product to achieve a maximum efficiency of 99.04%, minimizing the loss in the energy conversion process, it creates real economic benefits for customers. From extremely cold -40 ℃ to extremely hot +60 ℃, the equipment can operate stably. In the high temperature environment of 51 ℃, it can still guarantee the rated power without derating operation; at 40 ℃, it can even realize the long-term overload operation of 1.1 times the power. This excellent temperature resistance, so that it can calmly cope with all kinds of global climate conditions.
after the new product was released, hemai and tvsud formally held the signing ceremony of the strategic cooperation agreement for network construction certification. The two sides have carried out in-depth cooperation in the fields of testing and certification of grid-based energy storage products, standard system research, technology iteration and global market access, and jointly promote the upgrading of safety and compliance standards in the energy storage industry with the support of authoritative certification system.
go hand in hand
jointly expand the new blue ocean of energy storage
while releasing new products, wo mai has also accelerated the pace of ecological cooperation. During the exhibition, Wo Mai successively reached strategic cooperation with enterprises.
implement the national strategy
he mai and Henan pinggao smart energy co., ltd., a core enterprise of China electrical equipment group, signed a strategic cooperation framework agreement to integrate the superior resources of both sides in the field of equipment manufacturing and energy storage system around the “30-60” double carbon target, and jointly opened up a broader market space.
deepen the integration of “investment, construction and operation”
he mai has reached a strategic cooperation with China gezhouba group mechanical and electrical construction co., ltd. focusing on key links such as energy storage project development, investment and construction, forming an integrated coordination mechanism of “investment, construction and operation. The two parties will rely on their respective advantages in capital, engineering construction and technical equipment, and explore innovative models such as joint ventures and cooperation, and further expand to multiple scenarios such as wind power, carbon assets, source network and storage, and promote deeper industrial collaboration and value co-creation.
In the energy storage business, he Mai has established a comprehensive partnership with Chuneng New Energy Co., Ltd. In order to give full play to the resource advantages of both parties in their respective fields, further promote long-term and in-depth pragmatic cooperation, and jointly explore, cultivate and expand the market, the two parties work together based on the principles of mutual benefit and complementary advantages.
more cutting-edge technologies and innovations are being presented at the exhibition site. All partners are cordially invited to visit the Helai booth to experience the highlights of new products at close range, exchange energy storage technologies and market trends in depth, and jointly discuss development opportunities and cooperation space under the new power system. Hall B1, Booth C08: Homay looks forward to meeting you on site.
