Why XST 2/3?
Turn the page — six reasons this cabinet earns its footprint.
Real-world impact
Backup power for the digital public-safety radio network. Together with a German project partner, more than 50 sites were installed across Germany and Switzerland — including complete planning of civil works, electrical installation, and construction through to final acceptance.
- Autonomous operation of emergency-network antennas for the legally required 72 hours — and well beyond, up to 12 days in the event of a complete power outage.
- Stable supply with minimal maintenance, even under extreme conditions.

Autonomy
72 h
In areas without a grid connection — or until one is established — the XST delivers round-the-clock power for mobile network towers, ensuring coverage in dead zones. On a “white spot” without grid access, combining the XST with photovoltaics provides continuous energy for the telecommunications site.
- Reduces CO₂ and particulate emissions, improving local air quality.
- PV-paired operation for fully autonomous, around-the-clock supply.
