Alpine Research Station Achieves Year-Round Clean Energy Operation with Breakthrough Inverter Tech
Zermatt, Switzerland | June 15, 2024
3-Phase System Defies Blizzard to Power Critical Science Mission
During a historic June blizzard, an advanced three-phase inverter system maintained uninterrupted operation at a 3,780m Alpine weather station, setting a new benchmark for high-altitude renewable energy. The technology proved vital on June 10 when temperatures plummeted to -23°C with 120km/h winds, and grid power failed for 6 hours.
Event Timeline
-
08:00, June 10: Grid failure during Category 3 snowstorm
-
08:03: Seamless transition to off-grid mode (<10ms transfer)
-
08:15: Battery discharge at 11.3kW (meets TP10KH peak spec)
-
10:30: PV array restarted through snow cover (120V startup)
-
14:00: Continuous power until grid restoration

-
Voltage Resilience: Maintained 415V±2% output amid 260-520V grid swings
-
Cold Weather Operation: 97% efficiency at -23°C (derating only >45°C)
-
Environmental Protection: IP65 enclosure withstood ice accumulation

Industry Impact
"This system redefines mountain energy security," stated the station director. "The 8,800VA three-phase output preserved 2TB/sec data processing during whiteout conditions." Documented achievements include:
“At 120km/h winds, we still recorded 96.7% conversion efficiency—this is clean energy conquering extreme environments.”
-
82MWh annual generation (97.8% PV conversion efficiency)
-
100% uptime during grid failures
-
Compliance with VDE 4105 and EN 50549-1 grid codes
