From September 16 to 18, 2026, the WBE2026 World Battery and Energy Storage Industry Expo will be held in Guangzhou. Given that the expo will establish a dedicated "PV Intelligent O&M Energy Systems" zone for the first time, and will focus on showcasing low-power cleaning controllers and wide-temperature-range power modules compatible with solid-state batteries and sodium-ion batteries, this development deserves the attention of relevant companies not only because of the new products on display, but also because overseas buyers are placing greater emphasis at an earlier stage on equipment compatibility, application-scenario matching, and the completeness of delivery documentation. For equipment manufacturers, system integrators, export companies, buyers, and after-sales service providers, this is more like an execution signal concerning product specifications, procurement standards, and preparation for cross-border delivery.

Clear Information Released by the Expo

The confirmed information includes the following: the WBE2026 World Battery and Energy Storage Industry Expo will be held in Guangzhou from September 16 to 18, 2026; this year's expo will establish a dedicated "PV Intelligent O&M Energy Systems" zone for the first time; the expo has clearly announced that it will focus on showcasing low-power cleaning controllers and wide-temperature-range power modules compatible with solid-state batteries and sodium-ion batteries; and it is expected to attract more than 15,000 overseas professional visitors, including procurement delegations from leading power station operators such as Saudi Arabia's ACWA Power and Spain's Iberdrola.

Based on the information disclosed so far, the expo's focus is no longer limited to the display of conventional batteries and energy storage equipment. It has further extended to supporting energy-system products related to power station O&M, with the exhibition direction clearly targeting cleaning control and power-supply compatibility in new battery application scenarios.

Changes Across the Supply Chain as Procurement Standards Move Upstream

Equipment Suppliers Serving Overseas Projects

The focus on low-power cleaning controllers and wide-temperature-range power modules compatible with solid-state batteries and sodium-ion batteries indicates that relevant manufacturers may need to provide clearer responses, during external promotion and project discussions, to buyers' concerns regarding product compatibility ranges, operating temperature ranges, energy consumption levels, and supporting interfaces. The initial impact may be felt in the preparation of technical documentation, prototype verification, bid parameter descriptions, and delivery consistency, rather than in price competition alone.

Power Station Operators and Integrated Procurement Teams

From the procurement perspective, the presence of procurement delegations from leading power station operators among the overseas professional visitors indicates that procurement decisions are increasingly focusing on the compatibility between O&M support equipment and new battery systems. For buyers, the items requiring further verification may include the completeness of technical specification documents, supply lists, test descriptions, after-sales support capabilities, and long-term O&M conditions, particularly whether the applicability of the products in cross-regional applications and different temperature environments is clearly stated.

Export and Delivery Service Processes

For export companies and supply-chain service providers, the changes signaled by this type of expo may not necessarily mean that the rules have already been formally adjusted. More likely, overseas customers are raising their documentation requirements during preliminary product selection, tender communications, and delivery reviews. Based on current observations, product descriptions, inspection reports, quality traceability records, packaging labels, spare-parts support plans, and after-sales response capabilities may all become key items reviewed during commercial negotiations and delivery confirmation.

Testing, Certification, and After-Sales Support Providers

If procurement concerns expand from individual equipment to application-scenario compatibility, testing service providers, certification-related companies, and after-sales service providers may also be affected. Related business changes are more likely to involve the explanation of test items, supplementation of technical documents, descriptions of operating environments, and cooperation in quality traceability. It should be emphasized that the information provided does not specify any changes to certification rules or mandatory standards. Therefore, this part is more appropriately understood as a potential increase in demand rather than the introduction of an established system.

What Should Be Verified Before Exhibiting and Accepting Orders

First Check Whether the Technical Documentation Can Support Procurement Inquiries

For relevant companies, the more practical preparation at this stage is to verify whether the technical parameters of low-power cleaning controllers and wide-temperature-range power modules are presented completely and whether they correspond to application conditions for different battery technologies. When targeting overseas customers, it is also worth reviewing in advance whether technical descriptions, product manuals, test data, and interface definitions are consistent.

Monitor Changes in Tender Wording and Procurement Lists

Since the expo will establish the relevant zone for the first time, companies should closely monitor whether subsequent procurement documents, project requirement descriptions, and technical-bid communications begin to distinguish more clearly between O&M support equipment compatible with solid-state batteries and that compatible with sodium-ion batteries. It is not yet possible to conclude from this that the market has established unified procurement thresholds, but as an early-stage demand signal, it deserves continued attention.

Evaluate Delivery and After-Sales Supporting Evidence in Advance

If overseas buyers' concerns extend further from equipment procurement to O&M continuity, companies should assess before accepting orders whether their existing delivery documentation covers installation, commissioning, spare parts, warranty, and fault traceability. Particularly in cross-border projects, after-sales commitments, quality records, and issue-response mechanisms may directly influence buyers' purchasing decisions.

Review Supplier Qualifications and Supply Stability

For system integrators and engineering contractors, it is also necessary to verify in advance whether they have stable supporting suppliers and whether they can ensure the continuous supply of controllers and power modules throughout the project cycle. The information provided does not specify particular delivery rules, but from a procurement perspective, supply continuity and the preparation of alternative solutions may become important considerations in actual execution.

This Is More Like an Early Signal of a Shift in Demand Criteria

From an editorial perspective, this information is currently better understood as an early signal at the market-execution level rather than as an established unified regulatory requirement or formal institutional change. The expo's first-time establishment of a dedicated "PV Intelligent O&M Energy Systems" zone, together with its clear emphasis on products compatible with solid-state batteries and sodium-ion batteries, indicates that both the procurement and exhibition sides are beginning to discuss separately the "O&M support capabilities under new battery technologies."

At the same time, the information provided does not include specific regulatory texts, mandatory standard numbers, certification criteria, or changes to procurement systems. Therefore, the industry needs to continue monitoring whether subsequent official statements become more detailed, whether procurement documents introduce clearer technical requirements, whether overseas customers specify more concrete compliance and delivery standards in tenders, acceptance procedures, and after-sales conditions, and whether market feedback will lead to more stable product-selection rules for relevant products.

How This Information Should Be Understood at the Present Stage

Overall, the information released by WBE2026 should not be simply understood as an expansion of the expo's subject matter. What deserves greater attention is the shift in procurement priorities reflected behind it: supporting equipment for solid-state battery and sodium-ion battery application scenarios is being identified and compared separately. For companies across the industry chain, the more appropriate approach at this stage is not to assume that the rules have already been fully implemented, but to regard this as a signal that overseas procurement requirements, technical-document reviews, and delivery preparation may become more detailed, and to verify as early as possible the completeness of their product descriptions, supporting capabilities, and project documentation.
