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
📉 At electricity price 0.36–0.38 €/kWh
✅ Savings: €72–85 per month

Further optimization options include lighting, cooling, and hot water – all controlled via the same storage platform.

🔌 Easy installation – no registration, no electrician

In contrast to many battery systems, the Sunpura S2400 is a true plug & play device :

✅ Ready to plug in – no electrician required
