About 40 journalists and content creators crowded the Sigenergy booth at Intersolar Europe in Munich on June 24, many of them getting their hands on the SigenMate 2700 Ultra for the first time. The company calls it a plug-and-play home energy system for small and medium-sized households. Sales open July 14, 2026, at 10:00 a.m. CEST, when full specifications, configurations and pricing are due. No price has been announced yet.
The hardware
The unit takes up to 4,000 watts of solar input through four MPPT trackers and can connect to as many as eight panels. It works with all plug-and-play microinverters. Two AC channels deliver up to 3,600 watts on the grid side, which Sigenergy says is above the industry average. For backup, up to three units can be linked in parallel at the same 3,600-watt ceiling.
The battery is lithium iron phosphate. A base module holds 2.68 kWh, and extra modules stack up to 18 kWh per tower. A built-in heating function keeps the battery working in cold weather. The casing is rated IP66, meaning it is sealed against dust and powerful water jets, and the company cites a six-layer safety design for indoor or outdoor mounting.
One caution for German buyers: balcony power plants registered without an electrician remain subject to the 800-watt feed-in limit. The higher ratings are meant for backup use and larger setups.
The app
The system is run through mySigen App 4.0. Its Sigen AI Mode learns how a household uses power, then decides when to store energy, use it or send it to the grid. It needs live data from a smart meter, and Sigenergy’s own meter or the Shelly Pro 3EM will do.
The update adds a 48-hour forecast of solar generation and consumption, an assistant built on SigenAgent, and an AI Insight feature that explains its decisions in plain language. Users can also describe their energy goals in everyday words and let the system set itself up. A Local Connection mode allows monitoring and control with no internet.
The company
Sigenergy was founded in Shanghai in 2022 by former Huawei and BYD managers and is known for larger systems, SigenStor and SigenStack. “SigenMate 2700 Ultra is designed to make residential energy storage easier to install, expand and use,” said Shirley Wang, general manager of global consumer business. The design has already won an iF Design Award.
