Chinese storage system provider Sigenergy has launched SigenMate 2700 Ultra, an AI-driven, plug-and-play energy storage system designed for households and outdoor applications.
It describes the system, recently unveiled in Germany, as a fully seamless retrofit solution for existing PV installations, enabling homeowners to store excess solar energy without replacing existing panels or microinverters.
The system supports a maximum PV input power of 4,000 W and includes four maximum power point trackers (MPPT), each supporting up to two strings, to optimize energy harvesting in installations affected by complex roof layouts or shading, the company said.
On the AC side, the system provides nominal on-grid output configurations of 800 W and 1,400 W, alongside a 1,400 W off-grid backup output. To support the startup requirements of larger household appliances, it can deliver peak output power of 1,800 W for up to 10 seconds, according to the manufacturer.
The modular architecture allows the SigenMate 2700 Ultra to scale according to household energy requirements. A system starts with a single 2.688 kWh battery module using 105 Ah LiFePO4 cells and can be expanded to 18.8 kWh with one host unit and six battery modules. For larger energy needs, parallel system expansion enables a maximum capacity of 56.4 kWh.
The system relies on LiFePO4 battery chemistry, with each module offering 2.688 kWh of capacity and maximum charge and discharge power of 1,800 W and 1,400 W, respectively. It measures 460 × 275 × 225 mm and weighs 29 kg.
Energy management is controlled through the mySigen App, powered by SigenAgent, which Sigenergy describes as the industry’s first all-domain AI agent. The platform continuously analyzes operational data and adjusts energy strategies through a perception, reasoning, and action cycle.
Trained on data from more than 30,000 operational systems across 47 countries, SigenAgent evaluates variables including local weather conditions, grid status, and electricity prices to determine the most cost-effective approach for storing, using, or exporting power, the manufacturer said.
The system also supports dual Time-of-Use (TOU) modes for manual peak-demand management and is compatible with Virtual Power Plant (VPP) applications, allowing users to participate in grid services.
Another key feature of the SigenMate 2700 Ultra is its 0 ms backup capability. While conventional backup systems typically require 10 to 20 milliseconds to switch over, Sigenergy’s system maintains uninterrupted power on the load side without additional accessories. This enables sensitive equipment such as servers, computers, and critical household appliances to continue operating during grid interruptions without rebooting or flickering, Sigenergy said.
Connectivity is supported by dual-band Wi-Fi 6 across 2.4 GHz and 5 GHz frequencies, with the ability to locally cache up to one month of operational data during internet outages. Designed for outdoor use, the system carries an IP66 dust- and water-resistance rating, C5-M corrosion protection, and operates across a temperature range of -20 C to 55 C.
Battery safety is managed through a six-layer protection system incorporating pressure relief valves, physical insulation pads combined with fire-retardant heat-resistant pads, full-coverage high-precision cell temperature sensors, and real-time power cable temperature monitoring to prevent high-current overheating.
The SigenMate 2700 Ultra is currently available for pre-order in Germany through the Sigenergy Official Store, Amazon, and retail partners. Between July 14 and July 28, 2026, early adopters can purchase the system for an introductory price of €999, reduced from the standard €1,199 price excluding VAT. Selected bundle offers provide savings of up to €600, the company specified.
Pre-orders for the wider EU consumer market will open from Aug. 18 to August 31, 2026, with all launch-period orders including a complimentary three-phase Sigen Smart Meter.
