Operates flawlessly in extreme temperatures (-4°F to 149°F), retaining 90% capacity at -20°C and 95% at 65°C—perfect for homes in harsh climates. Its modular design allows easy expansion: add 5kWh or 10kWh units to scale up to 30kWh+ for larger properties or higher energy demands.
Whether you’re building a new smart home, upgrading an existing solar setup, or preparing for frequent power outages, this battery delivers reliable, clean energy that adapts to your lifestyle. Its compact design (120cm × 60cm × 30cm) fits easily in utility rooms, and the plug-and-play system works with all major solar inverters—no complex rewiring required.
Provides complete energy autonomy for homes without reliable grid access. Combined with solar, it replaces noisy, polluting generators with silent, clean power.
Q: How long does it take to charge with solar panels?
A: With a 10kW solar system, it fully charges in 3–4 hours of peak sunlight. The built-in MPPT controller optimizes solar harvest, even on cloudy days.
Q: Can it work without solar panels?
A: Yes. It functions as a standalone backup system, charging from the grid during off-peak hours to provide power during outages or peak times.
Q: Is professional installation required?
A: We recommend certified electrician installation for safety and warranty validation, but the plug-and-play design simplifies the process (typically 2–3 hours).
