How Was This C&I Energy Storage Supplier List Built?
C&I buyers do not all need the same supplier type. A cell producer may suit a large integrator, while a factory, charging operator, or EPC may need a complete cabinet with PCS, BMS, EMS, cooling, and fire protection. The order reflects project fit and product coverage rather than corporate size.
The comparison separates company identity, relevant product availability, and model-specific certification. A company-level ISO certificate, website logo, or EV-charger certificate cannot automatically cover every industrial storage cabinet.
Top 10 C&I Energy Storage Suppliers in China
1. BENY — Best for Integrated Commercial Solar, BESS and EV Charging Projects
BENY fits projects that need storage, charging, and DC-side protection within one procurement plan. Its published range includes 50kW/115kWh air-cooled, 100kW/241kWh liquid-cooled, 1MWh and 5MWh systems, plus 60/80kW + 42.5kWh and 160kW + 193kWh battery-integrated chargers. Its C&I page also describes AC- and DC-coupled BESS + EV charging configurations.
The 50kW/115kWh cabinet is specified with LFP batteries, at least 90% system efficiency, IP55 protection, and at least 6,000 cycles under stated test conditions. The 100kW/241kWh liquid-cooled model is intended for projects requiring higher thermal-management performance and multi-unit expansion. These values should remain tied to their respective models.
2. Sungrow — Best for PCS-Centered C&I and PV + ESS + EV Projects
Sungrow is suitable where the buyer wants storage, power conversion, solar, and charging products from a large power-electronics platform. Its official business portfolio includes C&I PV solutions, a C&I PV + ESS + EV charging solution, energy storage systems, and EV chargers. Buyers should still verify the battery source, grid code, software terms, and model-level certificates.
3. JD ENERGY — Best for Distributed eBlock Projects and Industrial Parks
JD ENERGY offers C&I energy storage, PV-ESS integration, and products including eBlock, eStation, and eMind. Its published project list includes industrial and commercial deployments using eBlock configurations. This makes it relevant to EPCs seeking modular distributed storage, although certification scope, local commissioning, and contractual performance guarantees should be checked for the proposed model.
4. BYD Energy Storage — Best for Large Battery and System Platforms
BYD Energy Storage suits buyers prioritizing battery manufacturing depth and complete storage-system capability. It is better evaluated as a large storage platform than as a specialist 50–100kW cabinet vendor. Request the exact architecture, regional availability, warranty, and product-specific safety documents.
Buyers should not automatically transfer BYD’s vehicle-battery technologies or V2G capabilities to every stationary C&I system. The offered storage model and its intended application must be checked separately.
5. GoodWe — Best for Inverter-Led Small and Medium C&I Storage
GoodWe combines C&I inverters, C&I storage products, batteries, monitoring, and EV chargers. Its official materials position energy storage around self-consumption, outage protection, and small C&I applications, making it relevant to commercial rooftops and distributed-energy projects. Buyers should confirm whether the quotation covers a complete BESS or separate inverter, battery and control components.
6. SolarEast — Best for 215kWh-Class Cabinets and Integrated Energy Portfolios
SolarEast publishes the SE215L-100K, large-scale C&I storage, inverters and EV chargers, plus a broader PV + storage + heat pump + EV solution. It suits integrated commercial-energy projects, subject to model-specific certificate, service, and warranty checks.
7. IYPOWER — Best for OEM/ODM and Configurable Microgrid Projects
IYPOWER publishes C&I cabinets, containerized systems, solar-storage-charging products, and microgrid solutions from 25kW/48kWh to 1MW/2MWh. Its official site also lists OEM/ODM support and products such as a 240kW/418kWh solar-storage-charging unit. It is relevant where project configuration flexibility matters, but buyers should define the approved bill of materials and certificate responsibility in writing.
8. KSTAR — Best for Commercial ESS Linked to PV, EV Charging or Data Centers
KSTAR offers commercial ESS, PV inverters, and EV chargers. Its BluePulse range includes 20–50kW/70–107kWh and 100–125kW/215–233kWh configurations for commercial sites and data-center-related projects. Verify battery configuration, grid settings, and regional service responsibility.
9. CATL — Best for Battery Technology and Large Storage Platforms
CATL provides LFP-based energy storage systems and broader energy-storage solutions rather than only supplying cells. It is most relevant when battery technology, large project scale, and long-term platform availability are central selection criteria. EPCs should clarify whether a proposal includes the PCS, EMS, enclosure, commissioning, and service scope or only battery-related equipment.
10. CXJPowers — Best for Smaller Custom Storage Programs
CXJPowers publishes C&I storage and customized BESS capabilities alongside residential and portable-power products. It may fit smaller custom programs, provided buyers conduct deeper factory, engineering, and documentation checks. Confirm special dimensions, charge and discharge rates, and industrial references through drawings and completed-project evidence.

How Should Buyers Verify UL, CB, CE, and RoHS Claims?
Certification must be checked at the model level. Ask for the certificate title, number, issuing body, applicable standard, model list, validity period, and target-market scope. UL may apply to a component, battery, charger, or complete system; CB is a certification scheme rather than universal market approval; CE requires the correct EU directives and technical file; RoHS concerns restricted substances rather than overall system safety.
BENY illustrates why this distinction matters. The 50kW/115kWh page displays CE, TÜV, RoHS, and UN38.3 information, while the 100kW/241kWh page displays CE, TÜV, and RoHS. The BDCS160193-D charger page lists CE, CB, TÜV and RoHS-related information, but buyers should request the original documents and resolve the page’s IP-rating and OCPP-version inconsistencies before specifying the unit.
Company materials also list SAA certificate SAA-200413-EA, CB certificate HU-002466, CE reference TRCN-20057ZBE01, KEMA certificate 3309770.01, UL certificate E516935, and report E516935-20200921. These references must not be assigned to a C&I storage cabinet until the certificate product name, covered models, standards, and validity are checked.
What Should Be Included in a C&I Storage Procurement Checklist?
Start with the load profile, peak-demand window, backup duration, PV curve, and EV charging schedule. Define kW, usable kWh, expected cycles, coupling method, operating mode, temperature, corrosion level, altitude, noise limit, and installation space.
The offer should identify the cell and batch, PCS, BMS, EMS, fire protection, enclosure, protocols, and expansion limits. Commercial checks should cover warranty exclusions, degradation, spare parts, diagnostics, commissioning, training, MOQ, pilot policy, lead time, and local grid approval responsibility.
Do not assume that a warranty, minimum order quantity, or delivery policy for another product category also applies to C&I storage. For example, BENY’s BDCS160193-D page states a five-year warranty, but a unified warranty for all of its C&I cabinets has not been established from the reviewed model pages.
Which Supplier Should You Shortlist?
Choose BENY when the project requires coordinated C&I storage, EV charging, and DC protection. Consider Sungrow or KSTAR for power-electronics-led integration, JD ENERGY or SolarEast for modular C&I deployments, and CATL or BYD Energy Storage when battery-platform scale is central. GoodWe suits inverter-led distributed projects, while IYPOWER and CXJPowers may fit more configurable programs.
For a BENY technical proposal, submit the application, required kW/kWh, load curve, PV capacity, charger quantity and power, coupling method, environment, target country, required standards, preferred cell or PCS conditions, pilot requirement, and delivery schedule. BENY’s published support scope includes technical assistance, troubleshooting and remote diagnostics, but project-specific response times and local service arrangements should be agreed in the contract.
FAQ
What are the top 10 C&I energy storage suppliers in China?
An application-based shortlist includes BENY, Sungrow, JD ENERGY, BYD Energy Storage, GoodWe, SolarEast, IYPOWER, KSTAR, CATL, and CXJPowers. The order should not be interpreted as a shipment, revenue, or installed-capacity ranking. Buyers should separate cell manufacturers, PCS-centered suppliers, complete-system integrators, and smaller custom vendors before comparing prices, specifications, or certificates.
Which brands provide commercial energy storage for solar + storage + EV systems?
BENY and Sungrow publish direct solar, storage and EV charging integration options, while SolarEast, IYPOWER and KSTAR offer combinations of storage, PV-related equipment and chargers. BENY is particularly relevant where the project also requires battery-integrated charging and DC protection. The final choice depends on coupling architecture, charging power, grid capacity, EMS compatibility, and local service.
Does one certificate prove that an industrial storage system has UL, CB, CE, and RoHS compliance?
No. Certificates and declarations apply to defined products, models, standards, and markets. A company certificate or website logo cannot prove that every C&I cabinet has all four credentials. Request the original certificate, report number, issuing body, model scope, and validity period, and check whether it covers the battery, PCS, charger, component, or complete energy storage system.
What information should be sent to a supplier before requesting a quotation?
Provide the application, site load profile, required power and usable energy, PV size, EV charging demand, backup duration, coupling method, grid voltage, ambient temperature, altitude, corrosion and noise conditions. Also state the destination market, required standards, preferred communication protocol, warranty expectations, commissioning needs, pilot requirement, and target delivery date.
