If you are sourcing microinverters from China, the shortlist is shorter than the marketing suggests. Five manufacturers actually ship at scale, carry grid approvals for the markets importers care about, and back the product with a warranty you can enforce: Hoymiles, APsystems, Deye, Envertech and TSUN. Everyone else selling a microinverter out of China is either one of these five under another label, or a smaller line from a string-inverter brand that added microinverters later.

This is a buying guide for distributors and importers, not a consumer review. The question it answers is which factory to build a supply relationship with, and what to check before the first container leaves. Rankings reflect shipment scale, how complete the product range is, and how widely the hardware is certified — not who advertises loudest.

Last updated: October 2026. Figures come from manufacturer datasheets, annual reports and the Wood Mackenzie 2026 inverter ranking. Models and grid approvals change by market, so confirm the exact SKU for your destination before you order.

One thing the table hides: on paper these products look almost identical. Peak efficiencies sit between 96.5% and 97.5% across the whole group, and nearly every current model caps the DC input at 60 or 65 V. The differences that matter to a buyer are elsewhere — input current, how the warranty is actually triggered, and whether the grid-code version you need exists as a stocked SKU or as a promise.

1. Hoymiles: the volume leader

Hoymiles, founded in Hangzhou in 2012 and listed on Shanghai's STAR Market in 2021 (688032), is the company most buyers mean when they say "Chinese microinverter". S&P Global Energy put its 2025 global microinverter shipment share at 17.4%, and on Hoymiles' own reckoning that makes it the largest microinverter supplier outside the United States. In June 2026 it entered Wood Mackenzie's global top ten inverter manufacturers for the first time, at sixth — the first time a microinverter specialist has ranked that high on a list that covers all inverter types.

The product that built the business is the 4-in-1. The single-phase HMS-2000-4T takes four modules on four independent MPPTs, with a 16–60 V tracking window, up to 16 A per input and a 2,000 VA peak output. The three-phase HMT-2000-4T covers the same power with two MPPTs shared across the four inputs, which is the version commercial rooftops usually want. Hoymiles also launched a 5,000 W 8-in-1 in 2024 and added an AC-coupled micro storage system the same year, so a distributor can now cover module-level conversion and small storage from one vendor. The Mexico factory that started production in 2024 matters too: it gives buyers facing US-content or tariff questions an option that does not ship from mainland China.

The catch is the ecosystem. Monitoring runs through the Hoymiles gateway and S-Miles Cloud, and long warranties are tied to the hardware being registered and online. Budget for the gateway in your landed cost, and read the warranty terms for the exact registration window before you quote a 25-year promise to your own customers.

2. APsystems: the multi-module pioneer

APsystems (Yuneng Technology) is older in this specific niche than its shipment rank suggests. Founded in 2010 with manufacturing in Jiaxing, Zhejiang and R&D split between Jiaxing and Cupertino, it shipped the YC500 duo early and spent a decade arguing that one microinverter per module was an expensive way to buy module-level control. The market eventually agreed: the dual and quad layouts are now what everyone else sells.

The current range is the DS3 family on the dual side and the QT2 on the three-phase quad side. A DS3 tracks two modules independently and reaches 730 or 880 VA depending on version, with 18–20 A inputs and a 26–60 V window. The QT2 connects four modules through two MPPTs and outputs 1,728 VA at 208 V or 1,800 VA at 480 V, which makes it one of the few Chinese microinverters genuinely aimed at commercial three-phase roofs rather than houses. Communication is encrypted Zigbee to an ECU gateway, and the standard warranty runs 10 to 12 years — shorter than Hoymiles on paper, though the hardware has a long field history behind it.

APsystems also made the Wood Mackenzie top ten in 2026, tied for tenth. For an importer, the practical advantage is the installed base: installers in many markets already know the EMA monitoring portal, so you are not asking them to learn a new platform.

3. Deye: best when you also sell storage

Deye is not a microinverter company. Ningbo Deye, founded in 2000 and listed in Shanghai (605117), makes string inverters, hybrid inverters, batteries and, less famously, dehumidifiers. Microinverters are one line inside that, running from 300 W to 2.2 kW, and the company shipped 139,000 of them in the first half of 2025 — down 43% on the year before, while its storage inverter shipments rose 48%. Read that as a signal: Deye's centre of gravity has moved to storage, and the microinverter line rides along with it.

That is also the reason to buy it. The G4 balcony range is built around the German plug-in rules specifically. The SUN-M80G4-EU-Q0 is an 800 W, two-MPPT unit limited to 60 V DC, and Deye rates its AC discharge at under 100 ms, inside the 200 ms the new DIN VDE V 0126-95 product standard asks for. The bigger SUN-M160G4 runs four MPPTs and 1,600 VA, with 18 A inputs so it can take today's 600 W-plus modules. Both talk over built-in Wi-Fi, so there is no separate gateway to buy, and the warranty runs 15 years on the small units (10 on the larger ones, 15 if the system is installed in Germany or Austria).

Choose Deye when your customer wants the microinverter, the hybrid and the battery from one brand with one monitoring app. If you only want microinverters, Hoymiles and APsystems have deeper catalogues.

4. Envertech: the value option that is still a real manufacturer

Envertech has built microinverters since 2015, with its factory in Yongkang, Zhejiang, sales and engineering in Shanghai, and a European office in Amsterdam plus a warehouse in Almelo. It is employee-owned and took a strategic investment from Sinomag in 2023. The pitch is uncomplicated hardware at a lower price: the EVT800, the volume model, connects two modules in the 180–550 W range, weighs about 4 kg and carries a 15-year warranty, with Wi-Fi built in on most versions.

There is less to configure and less to support, which is precisely why it suits a distributor whose customers are balcony kits and small rooftops rather than monitored commercial arrays. The trade-off is reach. Envertech sells into roughly 20 countries against 100-plus for the top two, and its grid-approval list is shorter, so check the certificate for your destination rather than assuming the European paperwork travels. Treat it as a strong second source for the price-sensitive end of your range, not as your only supplier.

5. TSUN: the one to watch on power

TSUN (TSUNESS), founded in Suzhou in 2019 by a team that came out of Eversolar, is the youngest name here and the most aggressive on product. It commercialised a plug-and-play solar kit in 2019, launched a single-phase microinverter at 3 kW before the rest of the market, and now lists models from 300 W up to 6,000 W — wider than anyone else on this page. The GEN3 Plus quad, the TSOL-MS2000, puts 2,000 W across four independent MPPTs with 16 A inputs, a 16–60 V window and 96.5% efficiency, at 5.5 kg with IP67 sealing and a 12-year standard warranty.

The company claims more than two million installations, says it was the first microinverter brand through VDE's latest EMC testing, and has opened offices in Germany, Brazil, India, Thailand, the UK and Singapore. It also raised money at a reported 200 million dollar pre-IPO valuation in 2023, and started building a much larger factory at the end of 2025. That growth story cuts both ways for a buyer. You get a hungry supplier with a broad, cheap range and fast product cycles. You also get a younger balance sheet and a shorter field history than Hoymiles or APsystems, so keep the first orders modest and watch the failure returns for two quarters before you commit volume.

Also worth a look

Several large Chinese inverter brands now sell a microinverter alongside their string ranges, and they are worth knowing even though none has the microinverter depth of the five above. Growatt (Shenzhen) sells the NEO 800M-X and NEO 2000M-X, aimed squarely at balcony systems and paired with its NOAH battery. Sofar (Shenzhen) offers the PowerNano MR series, two-MPPT and four-MPPT, and publishes full-power operation up to 60°C, which is a real spec in hot climates. SAJ (Guangzhou) added the M2 series. NEP (Northern Electric Power, Zhejiang) has been in microinverters for years and shows up on compatibility lists, though with a thinner international profile.

A warning about badges. A large share of the microinverters sold under European and Australian house brands are rebadged units from the factories above. If a brand cannot show you its own IEC 62109 test report with its own name on it, ask which factory actually builds the unit before you compare warranties.

The 800-watt trap: why your best market is also your most regulated

Germany is the centre of the plug-in solar boom, and it is where careless sourcing gets expensive. Since the Solarpaket reforms of 2024, the legal ceiling is 800 VA at the inverter and 2,000 W of modules, registration in the Marktstammdatenregister has been simplified, and tenants have a statutory right to install. Then the product standard arrived. DIN VDE V 0126-95, published December 2025, is the first dedicated product norm for plug-in solar devices, and it draws a line that most buyers miss: with an ordinary household plug, module power is capped at 960 W. Anything above 960 W and up to 2,000 W needs a dedicated energy connector such as a Wieland plug. The standard also demands defined protection measures for household-plug units — touch protection, an internal disconnection device, or galvanic isolation inside the inverter — and it excludes devices with a battery. A balcony kit with storage is, for now, outside the norm entirely.

Two sourcing consequences follow. First, the inverter's limit must be on the nameplate or the unit certificate. A software setting, even one locked by the manufacturer, does not count under VDE-AR-N 4105, so a "throttleable" 2,000 W unit is not an 800 W unit for this purpose. Second, your 800 W SKU and your 2,000 W SKU are different products with different connectors and different paperwork, not one product with a sticker changed. Order them that way.

Comparing microinverter suppliers for your market?

Match the inverter to the panel, not the other way round

Modern modules are what break old microinverter designs. A current 550–700 W module can deliver an Isc past 18 A, and the microinverter's maximum input current has to sit above that with margin. This is why the newer quads — Hoymiles HMS at up to 16 A, Deye's G4 at 18 A, TSUN's GEN3 Plus at 16 A — exist at all. A cheap unit rated at 12 or 13 A will silently clip a new module all year.

Do the same check on voltage. With the DC ceiling at 60 or 65 V on most of these products, you are connecting one module per input, and the module's open-circuit voltage at your coldest site temperature must stay under that ceiling. Then count MPPTs rather than inputs. A four-input unit with two MPPTs ties modules in pairs, which is fine on an unshaded commercial roof and wasteful on a balcony with two different orientations. The German balcony case is the clearest example: an 800 W unit with two MPPTs and a 1,120 W module allowance (the 560 W per input on Deye's SUN-M80G4) covers the 960 W household-plug tier with one orientation per input. The moment the customer wants the full 2,000 W, you have moved to a four-MPPT unit and a different connector.

What to check before you place the order

Prices converge. These seven points are where suppliers actually differ, so put them in your purchase contract rather than your spreadsheet.

  • Grid code by SKU, not by brand. Ask for the certificate that names your destination: VDE-AR-N 4105 for Germany, G98 or G99 for Great Britain, CEI 0-21 for Italy, AS/NZS 4777.2 for Australia, and UL 1741 with IEEE 1547 for North America. A CE mark alone covers none of these.
  • Input current against your module. Set the microinverter's max input current above your module's Isc, and check the short-circuit current rating separately. Then confirm the DC/AC ratio the warranty allows — some datasheets cap it at 1.35, others allow up to 1.5.
  • How the warranty starts. Several of these warranties only apply once the unit is registered on the manufacturer's portal within a set number of days. If your customers never connect the gateway, you are the one holding the claim.
  • Gateway and monitoring cost. Built-in Wi-Fi (Deye, Envertech, TSUN) costs nothing extra. A Sub-1G or Zigbee gateway (Hoymiles, APsystems) is more stable on large roofs and adds a line item. Price it in.
  • Connector brand. Stäubli MC4 compatibility is stated on some datasheets and vague on others. Mixed connectors are the most common source of hot joints in the field, so specify the connector maker in the order.
  • Spare-unit commitment. Microinverters fail as single units, which is the point of them, but only if you can replace one quickly. Agree a spare percentage and a ship-from location, ideally a warehouse in your region rather than a factory lead time.
  • Firmware control. Export limits, power-factor settings and grid profiles are firmware. Confirm you can set them for your market, and that a later update cannot silently change a unit you have already sold.

Where ShineTong fits

ShineTong is a B2B solar manufacturer and supplier based in China, and microinverters are part of what we ship — our own single, dual and quad units, the ST-500M, ST-1200D and ST-2800Q series, with OEM and ODM options. We are not on the list above, and we will not pretend otherwise. Hoymiles and APsystems move far more volume than we do, and their brand recognition is exactly why distributors pay a premium for them.

What we are good at is the part that sits around the logo. Buyers come to us when they want microinverters built under their own brand with a realistic minimum order, when they need the inverter and the rest of the system — connectors, cable, combiner boxes and DC protection — from a single supplier with one inspection and one shipment, or when they simply want a straight answer on which branded unit suits their market and their panel. Every shipment goes out with the grid approvals and test reports for the destination country, and we would rather tell you a product does not fit than ship it and find out later.

If you are pricing a container and want numbers you can compare, send us the destination country, the module model and the quantity. We will come back with workable options and lead times.

Frequently asked questions

Who is the largest microinverter manufacturer in China?

Hoymiles, based in Hangzhou and listed in Shanghai, leads Chinese microinverter shipments and says it ranks first worldwide outside the United States. It was also the highest-placed Chinese microinverter specialist in Wood Mackenzie's 2026 global inverter ranking, at sixth. Shipment rank is not the same as the best unit for your market, which depends on grid approvals and warranty terms.

Are Chinese microinverters allowed in Europe and the US?

Yes, when the specific model carries the grid approval for that market. For Europe that means the relevant national rule — VDE-AR-N 4105 in Germany, G98 or G99 in Britain, CEI 0-21 in Italy — on top of IEC 62109 safety testing. For North America it means UL 1741, IEEE 1547 and, where relevant, UL 1741 SB. Always match the certificate to the exact model number you are importing, because approvals do not automatically extend to the next variant in a series.

What is the difference between a 2-in-1 and a 4-in-1 microinverter?

A 2-in-1 connects two modules and usually has two independent MPPTs, so each module is tracked on its own. A 4-in-1 connects four modules; some models give each module its own MPPT, while others share two MPPTs across four inputs, tracking modules in pairs. Independent MPPTs matter most where modules face different directions or get partial shade. On a uniform commercial roof, shared MPPTs cost less and lose very little energy.

Can I connect a microinverter to a normal wall socket?

Only within the rules of your country, and Germany's are the strictest. Under DIN VDE V 0126-95, a plug-in solar device may feed in up to 800 VA, and it may use a standard household plug only up to 960 W of modules and only with defined protection measures. Above 960 W you need a dedicated energy plug. The inverter's power limit must be fixed on its nameplate, not just in software, and kits that include a battery are not covered by the standard yet.

How long does a microinverter warranty really last?

Stated warranties on this list run from 10 to 25 years, but most of the longer ones have conditions. The usual requirements are registration on the manufacturer's monitoring portal within a set period and a working internet connection to the gateway. Check who pays for shipping a replacement to your country, because a 25-year warranty serviced from a factory in China can cost more in freight than the unit is worth.
