Sungrow is a Chinese maker of solar inverters and energy storage, including SH series hybrid inverters and SBR and SBH batteries. Plants are monitored and managed in the iSolarCloud app and web portal, usually through a WiNet-S or WiNet-S2 communication module that connects the inverter by Wi-Fi or Ethernet.
Sungrow is built around its own cloud. The WiNet module sends data to iSolarCloud for the app, and Sungrow also offers an iSolarCloud Open API for approved developer access. For local access, Sungrow's WiNet-S/S2 manual says the module supports Modbus TCP, with port 516 on by default using SSL encryption and the plain port 502 disabled by default.
That suits people who want solar and battery data inside Home Assistant, openHAB or an energy management system. It is weaker for voice assistants and consumer smart home platforms: we found no Alexa, Google Home, Apple Home or Matter support, and community Modbus setups report problems on some newer WiNet firmware.

Sungrow's app for operating and maintaining solar and energy storage plants. It handles plant setup, remote parameter and WLAN configuration, generation trends, fault management and push notifications, weather, and micro-inverter commissioning. Sungrow's 2023 announcement says it has more than one million users in over 150 countries. The listing does not mention voice assistants or smart home platforms. Published by Sungrow Power Supply Co., Ltd. The Android link uses a package name from a privacy report, and we could not open Google Play to confirm it.

Sungrow's WiNet-S/S2 manual describes a module supporting WLAN and LAN, with an Ethernet port for the router. The module connects to iSolarCloud, and the manual does not mention cellular 4G.
The module's RJ45 connector handles RS-485 communication and power. The manual says it supports Modbus TCP and MQTT as northbound protocols, with port 516 enabled by default using SSL and port 502 disabled by default. Community reports describe a Modbus IP whitelist on the module and firmware changes that affect Modbus.
We found no Sungrow Matter announcement or product in the searches and pages we read, but did not search Matter certification databases, so this is unconfirmed.
The iSolarCloud listing does not mention it, and a search for Sungrow with Google Home and Alexa returned no Sungrow voice integration. We could not confirm either way.
We found no built-in Home Assistant integration. Community options exist. A popular YAML package uses Home Assistant's built-in Modbus integration over direct LAN or WiNet-S for SH*RT, SHx.RS, SH*K and SxT inverters. A WiNet-S add-on by NickS reads the dongle's WebSocket API and publishes to MQTT for newer SH-RS inverters, but blocks the dongle's web interface while it runs. A HACS integration uses the cloud Open API and its author calls it early beta tested on one system.
A Sungrow app by developer RM de Gruijter is labelled official by its developer, but Homey's page does not say Sungrow makes or endorses it. It uses the cloud and refreshes about every 5 minutes. It lists Homey Cloud, Pro, Pro mini and Self-Hosted Server, with Homey Bridge marked required for each device. A second community app named Reflexion also lists Sungrow, which we did not open.
An official Modbus Sungrow binding is in openHAB's add-on list for SH3.0-6.0RS, SH8.0-10RS, SH5.0-10RT and SH5-25T. With a WiNet-S it needs Modbus enabled and the whitelist disabled or openHAB added. The page says not all models are tested and some values depend on firmware. Sungrow does not maintain it.

SmartgridOne documents monitoring Sungrow inverters through the iSolarCloud Open API. Setup needs the inverters in an iSolarCloud account and an API Key, Access Key and RSA Key from Settings, Open API.
Sungrow runs a developer portal. A third-party client's README says you need an iSolarCloud account, a developer portal account and an application to get an app key and secret key. It also supports OAuth2 and encrypted calls with an RSA key. We did not open Sungrow's own developer pages, so terms and rate limits are unconfirmed.
Sungrow's WiNet-S/S2 manual lists Modbus TCP and MQTT, and says a local HTTPS web interface is reachable on port 443. Community reports say some firmware versions encrypt or restrict Modbus access, and we could not confirm which versions.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
Common questions about Sungrow
Does Sungrow support Matter?
Unconfirmed. We found no Sungrow Matter announcement or product in the searches and pages we read, but did not search Matter certification databases, so this is unconfirmed.
Does Sungrow work with Alexa?
Unconfirmed. The iSolarCloud listing does not mention it, and our search found no Sungrow skill. We could not confirm either way.
Does Sungrow work with Google Home?
Unconfirmed. The iSolarCloud listing does not mention it, and a search for Sungrow with Google Home and Alexa returned no Sungrow voice integration. We could not confirm either way.
Does Sungrow work with Apple Home (HomeKit)?
Unconfirmed. Not mentioned in the iSolarCloud listing and we found no integration. We could not confirm either way.
Does Sungrow work with Home Assistant?
Yes, through a community-built integration. We found no built-in Home Assistant integration. Community options exist. A popular YAML package uses Home Assistant's built-in Modbus integration over direct LAN or WiNet-S for SH*RT, SHx.RS, SH*K and SxT inverters. A WiNet-S add-on by NickS reads the dongle's WebSocket API and publishes to MQTT for newer SH-RS inverters, but blocks the dongle's web interface while it runs. A HACS integration uses the cloud Open API and its author calls it early beta tested on one system.
