About 40 press representatives and content creators gathered at the Sigenergy booth at Intersolar Europe in Munich on June 24 for a hands-on look at the SigenMate 2700 Ultra. The plug-and-play home energy storage system targets small and medium-sized households. Its official market launch was set for July 14.
Here is what the hardware offers. The unit accepts up to 4,000 W of solar input across four MPPTs 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 W on-grid, which Sigenergy says tops the current industry average. For backup, up to three units can be daisy-chained in parallel at the same 3,600 W ceiling.
The system carries an IP66 rating and a six-layer safety architecture, so it can go indoors or outdoors.
Shirley Wang, general manager of global consumer business at Sigenergy, opened the event. “SigenMate 2700 Ultra is designed to make residential energy storage easier to install, expand and use,” she said. Sigenergy already sells larger residential and commercial systems called SigenStor and SigenStack, and SigenMate is its attempt to cover smaller homes. Timo Wabnik, a senior account manager at Sigenergy DACH, led the technical session on input, storage scalability, backup, smart meter integration and parallel operation.
The software side
Think of the system as a battery box with a planner attached. The mySigen App 4.0 runs a 48-hour forecast of solar generation and household consumption. Its Sigen AI Mode learns how a home uses power and decides when to store energy, use it or export it. An assistant called SigenAgent handles device control and troubleshooting, while a feature named AI Insight explains the system’s decisions in plain language. Users can also type out their energy goals in natural language and let the app configure itself. A local connection mode keeps monitoring and control working without internet.
Pricing and pre-orders
Full specifications and prices were held back until launch day. When July 14 arrived, Sigenergy formally presented the product at a launch event and opened pre-orders in Germany through its official store, Amazon and partners such as Tepto. From July 14 to July 28, an early-bird price of €999 applied, down from €1,199 excluding VAT. Bundles could save buyers up to €600. EU customers outside Germany get a pre-order offer from August 18 to August 31, and every pre-order comes with a three-phase Sigen Smart Meter.
Capacity starts with a single 2.68 kWh battery module, and parallel setups can reach 56.4 kWh. The company says the unit operates from -20°C to 55°C and switches to backup with 0 ms of interruption, against 10 to 20 ms for the industry standard. By the end of 2025, Sigenergy reported a presence in 85 countries and regions, with 172 distributors and more than 17,600 registered installers.
