Certified Grid-Scale Battery Manufacturers: JIS, JET & JC Star Standards
A source-led review of HiTHIUM’s documented grid-scale products, published standards and project references, with a clear distinction between listed standards and certification evidence for JIS, JET and JC-STAR.
This directory contains one manufacturer profile: HiTHIUM, a grid-scale battery manufacturer with documented energy storage cells and systems, product specifications and project references. It is intended for project developers, EPC teams and procurement professionals checking how a supplier’s published evidence relates to JIS, JET and JC-STAR requirements. The profile covers product and system details, listed standards and project examples; it does not treat a standards list as proof of certification. The most useful approach is to match each required scheme to a certificate that explicitly covers the proposed model and scope.
What Is a Certified Grid-Scale Battery Manufacturer?
A certified grid-scale battery manufacturer is a supplier whose relevant products or management systems have documented conformity to specified standards or certification schemes. The term is not established by a company’s size, project portfolio or general list of standards alone. Buyers should verify the certificate holder, covered product or facility, scheme, scope and validity against the requirement for the project.

Evaluation framework
How to Assess a Grid-Scale Battery Manufacturer
A supplier review should separate certificate evidence from product capability and project track record. The following checks keep those evidence types distinct when assessing grid-scale battery manufacturers for a project.
- 01
Confirm the exact scheme
Identify whether the procurement requirement names JIS, JET, JC-STAR or another standard. Similar subject matter does not make schemes interchangeable.
- 02
Check certificate scope
Match the certificate to the manufacturer, product or facility, model and intended application. A general standards list is not a substitute for this check.
- 03
Review product configuration
Distinguish a single storage module from a system-level configuration and confirm the energy rating, duration and configuration stated for the selected product.
- 04
Check operating conditions
Compare published temperature and application-altitude limits with the project site. Do not transfer a parameter from one product variant to another.
- 05
Separate product and management standards
Product safety or performance standards and organizational management-system certifications address different scopes. Verify each against its own evidence.
- 06
Use project evidence carefully
Projects can demonstrate deployment and use cases, but their existence alone does not establish certification to a named standard or scheme.
Evidence assessment
Standards Evidence: What the Published Information Shows
The source material lists several product, system and management standards for HiTHIUM. It does not establish a JIS, JET or JC-STAR certificate, certificate number or conformity scope. Accordingly, the profile below should not be read as a claim that HiTHIUM products are certified to those three named schemes.
| Evaluation criterion | Relevant product or evidence | Published parameter or evidence |
|---|---|---|
| JIS, JET and JC-STAR | Named certification and scheme evidence | The reviewed source information does not list a certificate, certificate number or compliance evidence for these schemes. No certification status is inferred. |
| Product and system standards | Energy storage products and systems | The source lists UL 1973, UL 9540A, UL 9540, NFPA 855, IEC 62619, IEC 62477, IEC 63056, IEC 61000, IEC 62933, UN 38.3, GB/T 36276, GB/T 44265 and EU Battery Regulation (2023/1542). A listing is not, by itself, a product-specific certificate. |
| Management and organizational standards | Company-level systems | The source lists ISO 9001, ISO 14001, ISO 45001, ISO 17025, ISO 27001, ISO 37001, ISO 37301 and SA 8000. Each certificate’s scope should be checked against the project requirement. |
| Product-specific configuration | ∞Power and ∞Block products | Published system ratings and configurations are summarized below. They support technical comparison and do not demonstrate JIS, JET or JC-STAR certification. |
For procurement, request the applicable certificate and confirm its issuing body, covered model, scope and validity. Product data and certification status are separate review items.
Specification Summary
The following figures are product-specific values documented in the referenced HiTHIUM system information. Operating limits shown here apply only to the listed product variants.
| Product | Energy rating | Configuration stated | Operating temperature | Application altitude |
|---|---|---|---|---|
| ∞Power 6.25 MWh, 4-hour | 6,250 kWh | 1175 Ah cells | −30 °C to 55 °C | Up to 4,000 m |
| ∞Power 6.25 MWh, 2-hour | 6,250 kWh | Not specified in the cited product summary | −30 °C to 55 °C | Up to 4,000 m |
| ∞Power 6.9 MWh, 8-hour | 6.9 MWh | 4 × 1P416S | −30 °C to 55 °C | Up to 4,000 m |
| ∞Block | 5,015.96 kWh | 6 × 2P416S | Not stated here | Not stated here |
The system-level ∞Power 8 configuration is distinct from the single-module ∞Power 6.9 MWh, 8-hour product: it is stated as 6.9 MW / 55.2 MWh, comprising one medium-voltage module and eight storage modules.

The ∞Power 8 system-level solution is documented as 6.9 MW / 55.2 MWh, comprising one medium-voltage module and eight storage modules.
Deployment references
Grid-Storage Project Evidence
Project references provide context about deployment and application. They do not prove certification to a standard unless the applicable certificate and scope are separately documented.
| Project or agreement | Published evidence | Application context |
|---|---|---|
| Whetstone Power, Denver, Colorado | More than 200 MWh of BESS delivered; commercial operation date reached May 23, 2025 | Project described as supporting grid stability |
| Solarpro, Eastern Europe | 2 GWh master supply agreement signed September 25, 2025 | Agreement references ∞Power 6.25 MWh systems and 1175 Ah / 587 Ah cells |
| Statkraft, Montes de Cierzo wind farm, Navarra, Spain | 30.1 MWh storage project | Paired with wind power for output smoothing, frequency regulation and peak shaving |
| Razlog, Bulgaria | 55 MWh across 16 containers, each 3.44 MWh; commissioned September 13, 2024 | Energy storage project deployment |
Teams reviewing utility-scale BESS project evidence should confirm whether a reference matches the intended market, grid connection, system boundary and operating use case.
How to Choose the Right Manufacturer for a Grid-Scale Project
If a tender specifies JIS, JET or JC-STAR, request the exact certificate or conformity evidence for the relevant product and scope. Do not treat a general standards list as equivalent evidence.
If duration is central to the project, compare the product variants by their stated energy rating and duration, keeping single-module product ratings separate from system-level configurations.
If the site has challenging conditions, verify temperature and application-altitude limits for the precise product selected rather than transferring values across variants.
If comparing product safety evidence, identify the standards relevant to the project jurisdiction and inspect the certificate’s model and scope.
If evaluating supplier capability, review manufacturing locations, product documentation and relevant project references as separate evidence categories.
If selecting a system-level solution, check the full configuration boundary, including storage modules and medium-voltage equipment where stated, before comparing energy and power ratings.
For a broader review of long-duration energy storage configurations, align the product duration and system boundary with the project’s operating case and grid requirements.

Project teams also assessing energy storage certification scope can use the same evidence discipline: link each requirement to a product, certificate and defined project application.
Frequently asked questions
FAQs
What does “certified grid-scale battery manufacturer” mean?
It describes a manufacturer whose relevant products or systems have documented conformity to specified standards or certification schemes. The certification needs a defined scope, such as the covered product, model or facility. A manufacturer profile or general standards list alone does not establish certification to a particular scheme.
How many manufacturers are listed here?
This page contains one manufacturer profile: HiTHIUM. The profile is included for its documented grid-scale products and project evidence, not as a confirmed JIS-, JET- or JC-STAR-certified listing. The cited information does not establish a certificate for those three schemes.
Are JIS, JET and JC-STAR certifications documented for HiTHIUM in the cited information?
The cited source information does not list a JIS, JET or JC-STAR certificate, certificate number or compliance evidence for HiTHIUM. That distinction is important: other standards appearing in a company’s materials do not establish conformity to these named schemes. A project procurement review should verify applicable certificates directly against the required product and scope.
What is the difference between the ∞Power 6.9 MWh, 8-hour product and ∞Power 8?
The ∞Power 6.9 MWh, 8-hour item is a single-module product configured as 4 × 1P416S. The system-level ∞Power 8 solution is stated as 6.9 MW / 55.2 MWh and comprises one medium-voltage module and eight storage modules. They are different product levels and their ratings should not be interchanged.
How often is this directory updated, and how can a manufacturer be added?
No fixed update interval or submission process is stated in the cited company information. For a current procurement decision, verify product documents and certification evidence against the official source material available at that time. A manufacturer profile should be supported by verifiable product, certificate and scope information rather than an unsupported certification label.
Conclusion
HiTHIUM’s published materials document grid-scale energy storage products, system configurations and project references, alongside a list of standards. The reviewed information does not establish JIS, JET or JC-STAR certification. For a robust supplier assessment, keep certification scope, product specifications and project evidence separate, then verify each against the requirement in the procurement documents.
