What’s It About?

The SigenMate 2700 Ultra is a storage system for balcony solar systems that buffers surplus solar power. The base unit offers 2.688 kWh of capacity and can be expanded to around 18.8 kWh with additional battery packs. The device handles up to 4,000 watts of PV output across four independent MPP trackers and can be connected to up to eight solar modules. During a promotional period the system was offered for 899 euros.

An integrated AI agent called SigenAgent plans charging and discharging strategies for the coming 48 hours through the mySigen app. Consumption patterns and weather data are taken into account. The system also works without an internet connection and allows local control.

Background & Context

The modular design allows up to three SigenMate units to be operated in combination, which makes a total capacity of up to 56.4 kWh possible. In the event of a power cut the system provides up to 3,600 watts through two AC connections; for short periods up to 1,800 watts are possible. The housing, classified to IP66, protects against dust and strong water and is designed for operating temperatures between -20 and 55 °C.

The device was given the iF Design Award 2026 and has a compact housing that can also be placed in living spaces. Important functions remain available without a cloud connection as well, which makes on-site maintenance easier.

What Does This Mean?

Households with balcony solar systems can increase self-consumption by buffering solar power
The AI-supported planning optimises the use of the stored energy on the basis of consumption history and weather forecasts
The modular expandability allows a step-by-step adjustment to actual demand
The backup power function can keep critical loads supplied during grid outages
The local control makes the system less dependent on cloud services and increases data sovereignty
