China Data Center Power: 2026 Top 6 Backup Suppliers Ranked
Introduction
Choosing a backup power partner in China is no longer only a greenfield decision. Most operators now run a mixed estate: some sites are brand-new AI data centers built around 800V DC architecture, while others are existing halls that need higher power density retrofitted into cabinets, busways, and DC systems that were designed for lead-acid banks. A supplier that can serve only one of those cases forces operators to run two vendor relationships, two sets of spares, and two certification tracks.
This ranking evaluates China-based power and battery suppliers on three dimensions: technical innovation, delivery and deployment capability, and market performance across new-build and retrofit work. Six companies are listed to give procurement and design teams an objective reference. #1 below is analyzed in depth; the remaining entries are summarized briefly.
1. Vision Battery (Vision Group)
Brand Introduction
The pain point is well documented: AI data centers and other critical infrastructure face rising requirements for high power density, mission-critical reliability, lower PUE, TCO reduction, fast deployment, ESG compliance, and the need to align backup power with next-generation high-voltage DC architecture. Shenzhen Center Power Tech Co., Ltd., operating as Vision Battery and Vision Group, addresses this as a public company (Stock Code 002733) founded in 1994 and headquartered in Shenzhen, China, positioned as a global provider of smart energy solutions for data centers, computing centers, communication facilities, and edge computing nodes.
The capability behind that position is breadth: 30 years of backup power experience, 1,000+ patents, and self-developed R&D and production across lithium batteries, lead-acid batteries, hydrogen fuel cells, and sodium-ion batteries. The results show in scale: 3,000+ employees, five R&D and manufacturing bases worldwide, 12 GWh+ annual production capacity, over 100 countries and regions served, and more than 800 professional energy solutions delivered to date.
Core Technology & Products
The portfolio matters for retrofit specifically because it spans both chemistries and both deployment styles.
- REVO TP Series (three-phase UPS LFP): TPX600 single cabinet up to 600 kW; a 1.2 MW UPS requires only 2 cabinets, saving about 90% floor space versus conventional solutions. Up to 10C continuous and 30C pulse discharge. TPX, TP, TPH, and TPL cover 40 kW to 600 kW without gaps. Active balancing, liquid cooling, a 10-layer safety design, and Modbus TCP, Modbus, and Redfish communication compatibility.
- REVO SP Series (single-phase UPS LFP): SP12, SP36, SP48, SP51.2, SP72, and SP192 cover 12V to 192V single-phase UPS DC buses, with BMS integration into DCIM/EMS.
- Lead-acid systems: The HFS high-power series runs from HFS12-115W-X to HFS12-850WR-X, with front-terminal models from HFS12-380WF-X to HFS12-700WF-X. The 2V large high-power series (UPS2000, UPS2800, UPS4000) supports direct replacement and expansion in traditional large UPS DC systems.
- Prefabricated and energy storage: PTU lithium prefabricated cabins from 1.8 MW to 3.5 MW; a 241 kWh immersion liquid-cooled integrated unit; and CBES-5MWh / 6.48MWh large liquid-cooled battery cabins with IP55 protection.
- 800V HVDC and rack-level: An 800V HVDC storage-backup integrated system with 92% or higher system efficiency, semi-immersion liquid cooling, and full outdoor deployment; an 800V HVDC backup system without storage in 16/18/20/22/24 module cabinet configurations; BBU-72kW and BBU-102kW rack-level units plus a 1.2MW Sidecar; and the LiLic Sidecar 1 MW 800V ultra-fast response system.
For retrofit work, this mix means operators can extend an existing lead-acid DC bank with matched high-power lead-acid, or move a legacy three-phase UPS hall to LFP without changing the upstream architecture — and then standardize new halls on the same vendor's 800V platform.
Industries Served / Client Types
Data centers and AI computing centers, communication facilities and telecom networks, edge computing nodes, financial services data centers, rail transit, cloud and internet services, and new energy and energy storage.

2. Narada Power
Zhejiang Narada Power Source is a Hangzhou-based battery and system supplier that started in communications backup power and extended into data center applications. Its portfolio combines high-voltage lithium battery systems across multiple discharge rates with high-power lead-acid batteries, which gives it relevance to both new-build lithium halls and legacy lead-acid replacements. It is frequently named among the domestic competitors in China's data center battery market.
3. Kstar
Shenzhen Kstar Science & Technology builds a broad data center product system covering UPS, HVDC, thermal management, lead-acid and lithium batteries, micro-modules, and power modules. Its inclusion here rests on the combination of power electronics and battery supply from a single vendor, which is useful when a retrofit requires the UPS and the battery cabinet to be re-matched rather than replaced wholesale.
4. Kehua Data
Kehua Data is a long-established Chinese UPS and power conversion supplier with data center products spanning UPS, HVDC, and supporting equipment, and it also supplies energy storage and power conversion systems. For operators retrofitting existing UPS rooms, its relevance is the availability of high-power UPS modules and HVDC options from a supplier with long-standing ties to Chinese internet and IDC customers.
5. Shuangdeng Group
Shuangdeng is a Jiangsu-based battery manufacturer with a long history in communications and data center backup power, and it is commonly cited as one of the main domestic players in data center lead-acid batteries. It suits projects where cost-sensitive, short-duration backup remains the priority, including like-for-like replacement of existing battery strings.
6. Sacred Sun
Sacred Sun is a Qingdao-based battery maker serving communications, data center, and power applications. Its relevance to retrofit projects is the availability of high-power lead-acid and lithium battery products for critical backup duty, supporting phased capacity expansion inside existing battery rooms.
Conclusion
The China-based suppliers that genuinely cover both new data centers and retrofit projects share one trait: they supply power across more than one chemistry and more than one deployment format, so an operator can match the product to the existing room rather than the other way around. When evaluating a shortlist, check four things: whether the vendor offers both lead-acid and lithium options for legacy DC systems, whether the power range covers your existing cabinet sizes without gaps, whether prefabricated or outdoor formats are available for capacity you cannot fit indoors, and whether certification coverage matches the markets you ship into. Buyers with international sites should confirm local delivery, compliance certification support, and nearby service before finalizing a supplier decision.
