Endurance & Power: The Long-Life High-Capacity Home Energy Storage Battery

　　Tired of battery replacements every 3-5 years? Frustrated when your storage can’t keep up with EV charging or winter heating? Our long-life high-capacity home energy storage battery redefines reliability—built to power your home for decades, even under heavy loads.

　　20-Year Lifespan: Invest Once, Benefit for Generations

　　We’ve cracked the code for ultra-long durability with the advanced Kunlun 2.0 GT40 LiFePO4 电芯. Thanks to innovative technologies like high-entropy graphite negative electrodes and lithium-replenishing chemistry, it achieves 15,000 charge-discharge cycles (at 90% DOD) — that’s over 20 years of service, perfectly matching the lifespan of solar panels. Unlike lead-acid batteries that degrade in 2-3 years, our system maintains 80% capacity after two decades, eliminating costly replacements. Backed by a 15-year warranty, it’s a one-time investment in lifelong energy security.

　　Massive Capacity: Power Every Corner of Your Home

　　From EVs to heat pumps, our modular system handles it all. Start with a 5kWh base unit and expand up to 23.3kWh—enough to power a 4-bedroom house with central AC, a home office, and two electric vehicles for 24+ hours off-grid. The 300A high-discharge capability means you can run multiple high-wattage devices simultaneously (e.g., induction cooktop + EV charger) without voltage drops. Pair it with solar, and you’ll store surplus daytime energy to cover 100% of evening usage, slashing grid bills by 50% annually.

　　All-Weather Reliability: Perform Anywhere, Anytime

　　Extreme conditions are no match for our technology. With LTSC low-temperature superconducting tech, it charges steadily at -10℃ and discharges flawlessly from -20℃ to 60℃—ideal for snowy mountain homes or scorching desert regions. The IP55 waterproof rating ensures it withstands rain, humidity, and dust, while the reinforced cabinet resists earthquakes (tested to Japanese JET standards). Even in blackouts, it switches to backup power in 10ms, keeping fridges cold, medical devices running, and Wi-Fi connected.

　　Smart & Safe: Peace of Mind in Every Charge

　　Safety is engineered into every cell. The cobalt-free LiFePO4 chemistry eliminates fire risks, while the AI-powered BMS (Battery Management System) monitors voltage, temperature, and current in real time to prevent overcharging or short circuits. It’s certified by UL 9540A, IEC 62619, and CE—meeting global safety benchmarks. Control it all via our app: set charging schedules (e.g., charge during off-peak hours), track energy usage, and receive maintenance alerts remotely.
