Top 3 Technical Solutions for Swiss Villas
1. Tesla Powerwall 3
Capacity: It has a capacity of 13.5 kilowatt-hours, and what’s interesting is that it can be stacked to reach a total capacity of 40.5 kilowatt-hours.
Swiss Advantage: One of its significant advantages for Swiss villas is its ability to operate smoothly even in extremely cold weather, specifically at -20°C.
Case Study: Let’s take a look at a real example. There’s a villa in St. Moritz where this battery system enabled the operation of an indoor pool and a sauna when the temperature dropped to -15°C. This shows just how reliable it can be in the cold climate conditions typical of Switzerland.
2. sonnenBatterie 10 Premium
Modular Design: 10→20 kWh expansion
Swiss Feature: Integrated with EnergySharing™ for peer-to-peer trading
Zurich Example: Reduced grid dependence by 92%
3. HighJoule Titan X Series
Custom Capacity: 10-30 kWh LFP battery
AI Optimization: Slashes peak tariffs by 40%
Compatibility: Seamless integration with most EU inverters
