Growatt: Balcony Solar Company Profile

Growatt was founded in 2011 and is headquartered in Shenzhen, China, making it a 15-year inverter manufacturer rather than a balcony-solar startup. The company is privately held, with reported investment from Sequoia Capital, in contrast to Anker Innovations' public listing on the Shenzhen Stock Exchange. Growatt's core business is residential and commercial solar inverters; its NEO and NOAH product lines extend that existing business into the balcony-solar and home-battery-storage niche.

Growatt's balcony-solar-relevant product history centers on two launches covered in press reporting: the NEO microinverter line, and a subsequent NEO+NOAH combined solution that pairs the microinverter with Growatt's NOAH battery-storage hardware. Both launches extend Growatt's pre-existing residential inverter business rather than representing a new market entry from scratch, distinguishing the timeline from purpose-built balcony-battery brands like Zendure's SolarFlow.

The NOAH line is Growatt's battery-storage product family for balcony solar and home energy storage. Growatt officially lists both a base battery capacity and a maximum expandable capacity per model, allowing buyers to scale storage by adding modules rather than only choosing a single fixed-capacity unit. On the control side, Growatt NOAH hardware and Growatt inverters support local Modbus TCP — enabled by default, unlike brands that require manual activation — alongside MQTT access via community bridges such as noah-mqtt and growatt2mqtt, with Homeassistant-Growatt-Local-Modbus as the most-referenced HACS integration for Home Assistant users.

Germany is the only country with confirmed VDE-AR-N 4105 grid-connection certification and documented retail availability found in this research for Growatt's balcony solar products. This does not rule out other markets — it reflects what this research was able to confirm directly, not a confirmed absence like Anker SOLIX's documented lack of US certification. As with other Shenzhen-manufactured balcony solar hardware, Growatt's component costs are subject to the same April 2026 China PV-component export-tax rebate removal that applies to Anker, EcoFlow, and Zendure regardless of where final assembly happens.

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. Growatt sits primarily in the microinverter/battery-maker layer, alongside Hoymiles, Deye, 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 both manufacturing their own battery hardware and selling packaged kits directly to consumers.

Growatt has described itself as the world's No. 1 residential PV inverter brand by shipments, a company-reported figure. Independent industry coverage has instead placed Growatt as the third-largest overall inverter maker, a different ranking scope that likely includes commercial and utility-scale inverters alongside residential units. Both figures can be accurate simultaneously because they measure different things — residential-only shipments versus total inverter shipments across all segments — so this profile lists them separately rather than treating one as a correction of the other.
