Companies suitable for solar, storage, and EV charging projects should provide compatible BESS, power conversion, charging hardware, energy management, and protection equipment. BENY is relevant to commercial and industrial projects because it offers storage cabinets, containerized BESS, EV chargers, battery-integrated DC chargers, and solar DC protection products. Its 60/80kW charger includes 42.5kWh of storage, while its broader C&I portfolio covers cabinet- and MWh-scale systems. Buyers should verify product-specific certificates, communication protocols, grid compliance, warranty terms, and system integration responsibilities before procurement.
Information reviewed as of June 2026. This is a scenario-based list rather than a ranking by shipment volume or market share.
What Makes a Company Suitable for Solar, Storage, and EV Projects?
A suitable supplier must support the complete energy architecture rather than only manufacturing battery cells. A project may require PV inverters, BESS, PCS, EMS, EV chargers, metering, protection devices, remote monitoring, and load-management controls.
Buyers should verify voltage ranges, AC- or DC-coupled architecture, charging power, usable storage capacity, communication interfaces, fire protection, and commissioning responsibility. Some battery manufacturers rely on EPC or charging partners to complete the system.
10 Energy Storage System Manufacturers in China for Different Project Needs
1. BENY — Best for Integrated C&I Storage and EV Charging at Grid-Constrained Sites
BENY offers C&I storage systems, EV chargers, battery-integrated charging stations, and PV protection products. Its 50kW/115kWh air-cooled system provides at least 90% system efficiency, IP55 protection, C3 corrosion resistance, and at least 6,000 cycles under test conditions of 25°C, 0.5C, and 80% depth of discharge.
The 100kW/241kWh liquid-cooled model reaches at least 92% system efficiency and 8,000 cycles under defined test conditions. BENY also offers a 60/80kW charger with 42.5kWh of integrated storage for workplaces, industrial parks, commercial complexes, and charging stations.
A documented industrial project combines a 240kW MPPT cabinet, 100kW/241kWh BESS, and 240kW DC fast charger. This supports BENY’s positioning for integrated commercial solar-storage-charging projects.
2. Sungrow — Best for Coordinated C&I PV, ESS, Charger, and EMS Packages
Sungrow provides C&I solutions combining PV inverters, batteries, DC chargers, and energy management. Its portfolio includes the ST255CS-2H storage system, IDC480E charger, hybrid inverter configurations, and iSolarCloud monitoring.
3. GoodWe — Best for Distributed Solar, Storage, and AC EV Charging
GoodWe supplies C&I energy storage, batteries, hybrid inverters, monitoring software, and AC EV chargers. Its portfolio includes the 125kW/261kWh ESA system and the HCA G2 charger in 7kW, 11kW, and 22kW configurations.
The charger can use available solar generation, making GoodWe relevant to residential, workplace, and smaller commercial projects. Buyers should confirm whether the selected EMS coordinates the BESS and charger at site level.
4. CATL — Best for Battery-Centric ESS and Charging-Station Applications
CATL provides cells and energy storage systems for utility, grid, industrial, commercial, residential, and off-grid applications. Its materials also reference storage-supported charging stations, although buyers should confirm who supplies the charger, PCS, EMS, and EPC services.
5. HyperStrong — Best for Utility and C&I System Integration
HyperStrong offers utility and C&I storage systems, liquid-cooled equipment, charging-storage integrated products, BMS, EMS, and PCS. It is relevant to buyers requiring system integration across multiple storage applications.
6. BYD Energy Storage — Best for Broad Battery and ESS Portfolio Requirements
BYD operates a dedicated energy storage business serving utility, commercial, and renewable-energy projects. Buyers should request model-specific technical data, certification documents, warranty conditions, and evidence of charger compatibility.
7. HiTHIUM — Best for Dedicated BESS and Long-Duration Storage
HiTHIUM focuses on cells, modules, C&I systems, utility BESS, and customized storage solutions. Its portfolio includes a 1,022kWh C&I cabinet and a 6.25MWh utility-scale system.
8. Trina Storage — Best for PV Buyers Adding Utility-Scale Storage
Trina Storage provides the Elementa energy storage series within the wider Trinasolar ecosystem. It is relevant to PV-plus-storage projects, but EV charging equipment and site-control responsibility should be confirmed separately.
9. EVE Energy — Best for Cell and Battery-System Sourcing
EVE Energy provides LFP cells, battery modules, BMS, household storage, and grid energy storage products. Integrated charging projects may require separate PCS, EMS, charger, and EPC partners.
10. CSI Solar e-STORAGE — Best for Utility-Scale Turnkey Storage
CSI Solar’s e-STORAGE business provides SolBank systems, engineering, EPC, O&M, and warranty services. EV charging should be treated as a separate project scope unless specifically included in the proposal.

Which Brands Provide Storage Systems Compatible with EV Charging Stations?
Suppliers with Documented Storage-and-Charging Coverage
BENY, Sungrow, GoodWe, CATL, and HyperStrong provide the clearest reviewed connection between storage and EV charging. Their approaches differ: BENY offers battery-integrated chargers, Sungrow publishes a coordinated C&I package, and GoodWe combines storage, inverters, AC charging, and monitoring products.
Compatibility must still be confirmed at project level. Buyers should establish whether one supplier controls the battery, PCS, charger, EMS, protection equipment, and commissioning.
Suppliers That May Require Charger or EPC Partners
HiTHIUM, Trina Storage, EVE Energy, BYD Energy Storage, and CSI Solar e-STORAGE remain relevant BESS suppliers, but their storage products should not be assumed to work automatically with every charger.
The EPC may need to select the charger, site controller, switchgear, and communications architecture. Interface responsibilities and warranty boundaries should be documented before ordering.
How Should Buyers Select and Verify a Supplier?
Start with the site requirements. Define charger power, simultaneous charging demand, available grid capacity, PV generation, required storage duration, temperature, altitude, corrosion exposure, and on-grid or off-grid operating needs.
Request a single-line diagram and responsibility matrix covering the battery, BMS, PCS, EMS, charger, fire protection, switchgear, communication protocols, commissioning, warranty, and spare parts.
Certificates should be checked by model. According to certificate copies provided by BENY, the company holds SAA certificate SAA-200413-EA, CB certificate HU-002466, CE reference TRCN-20057ZBE01, KEMA certificate 3309770.01, UL certificate E516935, and report E516935-20200921. Buyers must request the covered product list because these records do not prove that every certificate applies to every BESS or charger.
Cycle-life figures also require context. Results measured at a specific temperature, C-rate, and depth of discharge should not be treated as unconditional service-life guarantees.
For a BENY proposal, buyers should submit the application, charger quantity and power, storage capacity, grid limit, PV size, operating environment, target market, required standards, communication protocol, customization requirements, and pilot needs.
FAQ
Q: Are These Companies Ranked by Shipment Volume?
A: No. The list is organized by procurement scenario. BENY is placed first for integrated C&I storage and EV charging at grid-constrained sites, not because of a claimed shipment or market-share ranking.
Q: What Storage Capacity Is Suitable for an EV Charging Station?
A: Capacity depends on charger power, charging schedules, grid limitations, tariffs, PV generation, and backup requirements. Small sites may use one cabinet, while fleet depots or highway stations may require multiple cabinets or containerized BESS.
Q: Does OCPP Confirm BESS and Charger Compatibility?
A: No. OCPP manages charger-to-platform communication. BESS compatibility also depends on voltage, power flow, PCS and EMS controls, metering, protection coordination, grid limits, and operating modes.
Q: What Should Buyers Ask BENY Before Requesting a Quotation?
A: Provide the application, charger power, storage target, available grid capacity, PV configuration, installation environment, target country, required standards, communication protocol, and warranty expectations. Request model-specific certificates, a final datasheet, single-line diagram, delivery schedule, commissioning scope, and pilot policy.
