Deye: Balcony Solar Microinverter Company Profile

Deye's confirmed corporate history in this research begins with a 2007 restructuring under new capital, and the company has been publicly listed on the Shanghai Stock Exchange since April 2021, headquartered in Ningbo, China. This public-market listing places Deye alongside Hoymiles' STAR Market listing rather than the privately held structure of Growatt or the kit-reseller brands covered elsewhere in this cluster. Deye's core business is microinverter and battery-storage hardware — its SUN-M G4 microinverter series and BK battery-storage series are components that appear in cross-brand comparisons alongside Hoymiles and APsystems hardware, rather than a packaged consumer kit sold under the Deye name the way Anker SOLIX, EcoFlow, or Zendure sell theirs.

Deye's product history documented in PV trade press centers on two hardware lines: the SUN-M G4 microinverter series and the BK battery-storage series, both tracked here for their launch dates as part of the company's growth following its 2007 restructuring. Separately, PromptQuorum's own microinverter and Home Assistant integration research documents Deye's SUN600–1000G3 line specifically — the model most often placed in direct price-and-monitoring comparisons against Hoymiles' HMS series and APsystems' EZ1-M — evidence that Deye maintains more than one active microinverter family in parallel, rather than a single linear product line.

The SUN-M G4 series is Deye's current microinverter product line, with AC output officially listed across the range to match different panel counts and configurations, consistent with how Hoymiles and Growatt structure their own model lineups. Deye's SUN600–1000G3 line — the model most frequently benchmarked against Hoymiles' HMS-800-2T-NA (documented at roughly $279–290) and APsystems' EZ1-M ($325 direct from the manufacturer) — has no reliably confirmed US price in this research; only EU pricing for that line has been documented, leaving its US cost position unconfirmed relative to its two closest competitors.

Deye's own product pages list grid-code certifications on a country-by-country basis, consistent with how Hoymiles and Growatt document their regional compliance. This research was not able to itemize the specific certified-country list for Deye to the same level of confirmed detail found for Hoymiles' North America/Germany/France/Poland/Netherlands documentation — reflecting the limits of what this research could directly confirm, not a confirmed absence in any particular market. What is confirmed is that Deye's SUN600–1000G3 line has documented EU pricing, while no reliable US price was found for that specific model.

The balcony solar supply chain splits into three layers: panel manufacturers, microinverter/battery makers, and kit resellers that package the two into a consumer product. Deye sits in the microinverter/battery-maker layer, alongside Hoymiles, Growatt, APsystems, Enphase, and GoodWe — companies whose core business is the electronics that make a plug-in system grid-safe, not assembling and reselling complete consumer kits. This differs from Anker SOLIX, EcoFlow, and Zendure, which span two layers by manufacturing their own battery hardware and also selling packaged kits directly to consumers. Deye's hardware most often appears in direct, model-level comparisons against Hoymiles and APsystems rather than embedded invisibly inside a third-party kit, giving it a more consumer-visible profile within its supply-chain layer than some peers.

Deye microinverters carry confirmed UL 1741 and IEEE 1547 compliance, the established US grid-interconnection standards that predate the newer, balcony-solar-specific UL 3700 standard by years. No Deye product has completed UL 3700 certification, but this is consistent with the rest of the industry: the standard launched in January 2026 and, as of this research, no microinverter brand — Deye, Hoymiles, or APsystems included — has a certified product on the market. Deye's SUN600–1000G3 line defaults to monitoring through the SOLARMAN cloud platform, a platform shared across many budget-inverter brands rather than Deye-exclusive, but its Logger Stick hardware exposes an undocumented local Modbus TCP port (8899) that stays active across firmware versions — readable via the pysolarmanv5 library, the Solarman HACS integration, or the deye-inverter-mqtt bridge, none of which require a cloud account for that data path.
