🚗 Is your Tesla charging too expensive? With the Sunpura S2400, you can save over €70 every month.
The intelligent charging solution for e-car owners in Germany
Electricity prices in Germany continue to rise – in many places, EV drivers pay between €0.35 and €0.45 per kWh for home charging. Anyone who regularly drives 1,000 km per month (e.g., a Tesla Model 3 with approximately 15 kWh/100 km) will quickly pay the price:
-
📈 150 kWh x €0.38 = €57 per month
-
🚨 During peak loads or expensive basic suppliers: even more
The solution? Generate your own solar power, store it, and charge it selectively when it's worthwhile.
With the Sunpura S2400 system this is very easy.
⚡ The Sunpura S2400 system – your charging station with its own storage
The Sunpura S2400 is more than just a battery storage system. It's a modular all-in-one system with a hybrid inverter, LiFePO₄ battery, and intelligent control. When combined with three units, it delivers true three-phase current —ideal for high-performance wallboxes.
🔧 Technical highlights:
-
Power per unit: 2.4 kW (S2400 base + extension)
-
Triple setup (3 phases): 7.2 kW / up to 28.8 kWh usable storage capacity
-
Compatible with EV charging powers: 3.6 kW / 7.2 kW / 11 kW / 22 kW
-
Integration: Type 2 wallboxes, PV systems, dynamic tariffs, app control (also with Home Assistant)
☀️ Typical PV combination:
e.g. B. 2.1 kWp balcony system (10 × 210 W panels) = approx. 6.5–7.5 kWh/day in summer –
enough for 100 km daily range.
💶 Monthly savings: €70 and more
With electricity storage and self-consumption, Tesla drivers significantly reduce their grid costs:
-
🔋 Self-consumption instead of grid connection : up to 200–225 kWh/month
-
