Sungrow leads Vietnam’s 2025 energy-storage inverter ranking across utility-scale PCS, commercial and industrial storage, and residential hybrid systems. Huawei follows with strong commercial-storage and premium residential coverage. Deye ranks third overall and leads the residential hybrid-inverter segment, while Growatt, GoodWe, Solis, SMA, Kehua, Sineng and GG Power complete the top ten.
It presents a shipment-based market reconstruction from industry, export and channel evidence. The purpose is practical: to show which inverter brands are most likely to appear when a Vietnamese distributor, installer, solar company or project buyer compares storage equipment for a real project.
The ranking covers three product groups:
- Utility-scale battery energy-storage PCS;
- Commercial and industrial storage converters;
- Residential hybrid storage inverters.
That scope matters. A brand can lead the residential hybrid segment and still rank below a utility-scale PCS supplier in the full-market table because one large project can move annual shipment capacity by a significant amount.
How the Vietnam inverter ranking was built
CVC’s 2025 Vietnam ranking combines four evidence groups: third-party industry reports and Vietnamese energy media; public company filings and investor materials; China-to-Vietnam customs and export research; and local channel evidence from Hanoi, Ho Chi Minh City and Vietnam energy-storage exhibitions.
The source pack includes the Vietnam photovoltaic-inverter market research cited in the study, Vietnam battery-market research, Vietnamese market publications such as sieuthisolar.vn and ec-tech.vn, listed-company disclosures, China export tracking and local distributor feedback. Because these sources cover different parts of the market, the ranking uses cross-source reconstruction.
Calculation rules
| Calculation item | Rule used in this ranking |
|---|---|
| Core metric | 2025 full-year storage-inverter shipment capacity, measured in GW |
| Supporting metric | Shipment units used to calibrate capacity-based results |
| Utility-scale storage | 60% weighting |
| Commercial and industrial storage | 25% weighting |
| Residential storage | 15% weighting |
| Range data | Midpoints used when a source provides a market-share or shipment range |
The 60/25/15 weighting reflects Vietnam’s current market structure in the study. It also explains why the full-scenario ranking differs from a residential-only ranking.
Vietnam’s top 10 energy storage inverter brands in 2025
| Rank | Brand | Country / region | Main segment | Position in Vietnam |
|---|---|---|---|---|
| 1 | Sungrow | China | Utility, C&I and residential storage | Full-scenario leader across power ranges |
| 2 | Huawei Digital Power | China | C&I and premium residential storage | Strong ecosystem and smart-energy position |
| 3 | Deye | China | Residential hybrid storage | Residential hybrid leader; third overall |
| 4 | Growatt | China | Residential and small C&I storage | Broad distributor and installer coverage |
| 5 | GoodWe | China | Residential and small C&I storage | Strong high-voltage hybrid position |
| 6 | Ginlong / Solis | China | Distributed and C&I storage | Growing channel and local assembly presence |
| 7 | SMA Solar | Germany | Premium C&I and project storage | Strong international-project position |
| 8 | Kehua | China | Utility and C&I PCS | Large-power and liquid-cooled PCS strength |
| 9 | Sineng | China | Utility-scale PCS | Concentrated on large renewable-storage projects |
| 10 | GG Power | Vietnam | C&I and off-grid systems | Local assembly and service route |
The table is a market comparison starting point. The exact model, grid configuration, battery voltage, firmware and local service route still determine whether a brand fits a quotation.
1. Sungrow: the full-scenario leader
Sungrow ranks first because its product and manufacturing footprint reaches the three segments used in this study. The brand is visible in utility-scale renewable-plus-storage projects, commercial systems and residential storage. Its position is therefore supported by both large project capacity and a broad inverter portfolio.
For a project buyer, Sungrow should be evaluated as a complete power-conversion and storage platform rather than as a single inverter model. Utility projects may require high-power PCS, system controls, cooling, fire integration and grid-support functions. Commercial and residential projects bring a different set of requirements: battery voltage, backup output, monitoring, installation space and commissioning.
Before a quotation is fixed, request the exact PCS or hybrid-inverter model, rated AC power, DC voltage range, cooling method, communication interfaces, grid-code documents and battery compatibility information. For a Vietnamese project, the local EPC or service partner is part of the equipment decision.
2. Huawei Digital Power: an ecosystem-led commercial and residential choice
Huawei ranks second through its digital-energy ecosystem. The brand is especially strong where storage is sold together with solar inverters, monitoring, energy management and a structured installation route. This gives Huawei a clear advantage in commercial facilities and premium residential projects that value a coordinated platform.
The manufacturing and supply story is system-oriented. Buyers compare an integrated Huawei energy solution built from an inverter, battery module, controller, monitoring platform and commissioning service. The quotation should identify each part and its responsible supplier.
Important checks include the supported battery architecture, communication profile, firmware version, backup output, three-phase requirements, remote-service permissions and warranty territory. A distributor should also confirm which parts can be stocked locally and which services require an authorized installer.
3. Deye: the residential hybrid-inverter leader
Deye ranks third in the full-scenario table and first in the residential hybrid-inverter segment. The supplied Vietnam channel study estimates its local residential hybrid share at about 22%. This channel estimate explains why Deye appears so often in residential quotations and installer comparisons; the full ranking also includes utility and commercial shipment capacity.
Deye’s factory and product strategy centers on a broad hybrid-inverter family, value-oriented pricing and a strong channel route. The brand is especially relevant in southern provinces where installers need flexible configurations for solar self-consumption, backup loads and weak-grid operation.
The practical buying check is model-level compatibility. Confirm MPPT voltage and current, battery voltage range, EPS or backup output, single-phase or three-phase configuration, CT or meter arrangement, generator input, CAN/RS485 communication and firmware version. The same brand can produce very different project outcomes when the battery size and essential-load panel change.
4. Growatt: broad channel coverage for residential and small C&I storage
Growatt ranks fourth with strong exposure in distributed solar, residential storage and small commercial rooftop systems. Its presence is less dependent on one very large project and more dependent on repeated distributor and installer activity across the market.
The brand’s manufacturing and product system covers single-phase and three-phase hybrid inverters, monitoring and battery-linked storage solutions. This breadth is useful for distributors that want one recognizable product family across several customer segments.
The quotation should show the exact inverter model, battery options, continuous backup power, PV input range, phase configuration, monitoring method and local warranty contact. For channel sales, model continuity and spare-parts availability matter as much as the headline inverter efficiency.
5. GoodWe: high-voltage hybrid storage for premium residential and small commercial projects
GoodWe ranks fifth and has a clear position in residential and small commercial storage. Its high-voltage hybrid systems are relevant to projects that need a more integrated battery architecture, compact installation and a structured solar-plus-storage package.
GoodWe is best evaluated through the complete system: hybrid inverter, high-voltage battery, backup circuit, monitoring and installation procedure. The product value sits in the relationship between battery voltage, charge and discharge limits, usable energy and the loads that remain online during an outage.
Installers should request the current compatible-battery list, maximum continuous charge and discharge power, backup-output data, parallel-expansion rules, firmware requirements and local service procedure. These documents make a GoodWe quotation easier to compare with other high-voltage systems.
6. Ginlong / Solis: distributed-storage and C&I channel strength
Ginlong, commonly encountered through the Solis brand, ranks sixth in the Vietnam full-scenario assessment. Its strength is concentrated in distributed solar and small-to-medium commercial storage, where installers compare product availability, system cost and commissioning support.
The supplied study also points to localised assembly capacity and continued growth in exported string and storage-inverter products. The final article should identify the exact local supply entity and model range before publication, because “local presence” can describe a factory, an assembly site, a distributor or a service partner.
The procurement file should include the exact Solis model, battery compatibility profile, grid voltage and frequency, PV input, backup function, communications and warranty responsibility. Channel buyers should also ask whether replacement units and firmware support are available in Vietnam.
7. SMA Solar: a premium project route
SMA ranks seventh in the shipment-based table and remains important in foreign-invested companies, premium commercial installations and projects designed around international engineering standards. The supplied study places its Vietnam share in an estimated 8%–12% range; this range is derived from the study’s evidence set.
SMA’s value comes from premium power-conversion engineering, established international project experience and a strong fit with buyers who put documentation and engineering consistency ahead of the lowest equipment price. The overall shipment volume is smaller than the largest Chinese brands because the project mix is more selective.
Before ordering, confirm the grid standard, project engineering responsibility, service contract, spare-parts route, commissioning process and battery compatibility. A premium brand still needs a clear local support plan.
8. Kehua: high-power PCS and liquid-cooled storage capability
Kehua ranks eighth with strength in utility-scale and commercial storage PCS. Its position is linked to large-power conversion, liquid-cooled storage and project-level delivery rather than consumer-facing residential retail.
For a Vietnam project, Kehua is relevant when the buyer needs a coordinated PCS and battery-storage package, especially for larger renewable-plus-storage or commercial systems. The factory and engineering discussion should include PCS power, cooling, container layout, fire-control interfaces, EMS communication and grid-support functions.
The quotation should clearly separate the PCS scope, battery scope, EMS, transformer or switchgear scope, fire system and commissioning responsibility. A clear system boundary prevents an apparently attractive PCS price from hiding missing project equipment.
9. Sineng: concentrated on large renewable-storage projects
Sineng ranks ninth and is primarily associated with high-power, centralised storage PCS. Its Vietnam opportunity is strongest in wind and solar projects that need storage as part of a broader power-generation and grid-support package.
Sineng should be compared with other utility-scale PCS suppliers on more than conversion efficiency. Project teams need to examine grid-support functions, operating envelope, system controls, communications, cooling, availability strategy and the engineering company responsible for integration.
The procurement package should include the exact PCS model, DC operating range, AC connection requirements, control architecture, protection settings and technical support route. The brand is a project-equipment decision rather than a small residential-retail purchase.
10. GG Power: a Vietnamese local assembly and service route
GG Power ranks tenth and is the highest-positioned Vietnamese-owned brand in the supplied study. Its strength is local assembly, local communication and service access for small commercial, off-grid and microgrid projects.
Local assembly can be valuable when the buyer needs faster technical communication, local installation coordination or a system adapted to Vietnamese project conditions. It also creates a different procurement question: which parts are made locally, which components are imported, and which company carries the final system warranty?
Before ordering, request the system architecture, core component origins, rated power, battery interface, local service address, replacement-part plan and project references that can be verified. These documents turn a local-brand advantage into a usable supply route.
What this ranking means for Vietnam buyers and distributors
The ranking gives buyers a market map, but the purchase decision still starts with the application.
1. Choose the inverter segment before choosing the brand
A utility-scale PCS, a 100 kW commercial inverter and a 5 kW residential hybrid inverter solve different problems. Comparing them only by brand recognition produces a poor shortlist.
2. Deye’s residential position does not change the full-market ranking
Deye leads the residential hybrid segment in the supplied channel data. Sungrow and Huawei remain stronger in the full-scenario calculation because utility and commercial projects carry more weight.
3. Check the battery interface before comparing efficiency
The inverter must match the battery voltage, BMS communication, charge and discharge current, firmware and operating mode. The battery and inverter compatibility guide explains why model-level documents are essential for compatibility.
4. Local service is part of the product
Ask who performs commissioning, firmware updates, fault diagnosis, warranty replacement and spare-parts delivery in Vietnam. A local route should be written into the quotation.
5. Channel buyers need a product ladder
Distributors normally need separate products for residential backup, small commercial systems and larger projects. One inverter family rarely covers all three profit and service requirements.

Brands outside the top 10 and ranking boundaries
An outside-the-top-ten position can reflect limited Vietnamese channel evidence, a small number of project deliveries or incomplete public data for a full-year comparison. The position alone does not describe the technical quality of the product.
Utility-scale delivery also creates annual volatility. One delayed project can move a brand’s shipment capacity into the following year. Use the ranking as a shortlist for technical and commercial investigation, then verify the exact project fit.
Frequently asked questions
Which energy storage inverter brand ranked first in Vietnam in 2025?
Sungrow ranked first in the supplied full-scenario assessment because it combines utility-scale PCS, commercial storage and residential products across a broad Vietnam project base.
Is Deye the number-one storage inverter brand in Vietnam?
Deye ranked first in the residential hybrid-inverter segment in the supplied channel study. It ranked third in the full-scenario ranking because the calculation also gives substantial weight to utility-scale and commercial storage.
What is the difference between a PCS and a residential hybrid inverter?
A PCS is normally designed for larger battery-storage systems and project-level power conversion. A residential hybrid inverter combines solar, battery and home-load functions in a smaller system architecture. Their power range, control functions, installation requirements and service model are different.
Which parameters should Vietnamese installers check before ordering?
Check rated power, battery voltage, charge and discharge current, PV input, phase, frequency, backup output, BMS communication, firmware, grid requirements and the exact compatibility list.
Does a high shipment ranking guarantee local after-sales support?
No. The quotation should identify the Vietnamese distributor or installer, commissioning responsibility, warranty territory, replacement process and escalation contact.
Conclusion
Vietnam’s 2025 storage-inverter market has three clear layers. Sungrow leads the full-scenario market through utility, commercial and residential coverage. Huawei is strongest where storage is sold as part of a coordinated digital-energy ecosystem. Deye leads residential hybrid storage, while Growatt, GoodWe and Solis remain important channel brands. Kehua and Sineng are more relevant to large PCS projects, and GG Power provides a local assembly and service route.
The right brand is the one that matches the project’s power range, battery architecture, grid requirements, service route and supply plan. CVC helps distributors, installers and project buyers compare inverter models, battery compatibility, technical documents and available supply routes for Vietnam projects.
Research basis and scope
This article is based on CVC Energy’s 2025 Vietnam storage-inverter shipment study. The study combines third-party market research, public company disclosures, China-to-Vietnam export tracking and Vietnamese channel evidence. The listed ranking is a cross-source reconstruction of brand shipment positions; the source pack does not provide a single public official table of exact brand shipments.
The calculation uses 2025 annual shipment capacity with a 60% utility-scale, 25% commercial and industrial, and 15% residential weighting. The ranking describes shipment position; technical fit, compatibility, market-share precision and local warranty performance still require model-level confirmation in the quotation stage.
