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

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
