Sigenergy x Shelly
Sigenergy and Shelly devices work together natively inside the mySigen app, with deeper integration possible for users who want live data on a Shelly device or programmatic access via the Sigenergy OpenAPI. This page is an overview - the detailed guides live on the sub-pages below.

What this integration is
Sigenergy (brand name: Sigen) is a manufacturer of residential and small-commercial solar inverters, battery storage, and EV chargers. The flagship SigenStor system combines a hybrid inverter, modular battery packs, and an AC-coupled gateway in a single platform managed through the mySigen mobile app.
Shelly support is built into mySigen: you can add Shelly smart switches and plugs as controllable loads, schedule them around generation and tariff windows, and see their consumption alongside the rest of your system. Beyond that, any Shelly device with scripting capability can mirror live Sigenergy data - PV, battery, grid, load - as Virtual Components, with three setup recipes documented below.
Who is this page for?
Pick the guide that matches how you use Sigenergy:
For Sigen owners - if you own a Sigenergy system at home. What's built in, how to add Shelly devices, and what to expect from load control.
For installers - if you commission Sigenergy systems. Pre-installation site surveys with Shelly Pro EM and Pro 3EM (consumption profile, sizing data, phase-sequence verification), choosing the right Shelly models for per-circuit data in mySigen, and tips for preparing devices for pairing.
For DIY & developers - if you want to put live Sigenergy data on a Shelly device, or build on top of the Sigenergy OpenAPI. Three working recipes, plus full API and Modbus reference.
