20.48 kWh (HJ-H20-H10) and 25.6 kWh (HJ-H25-H15) capacities with LiFePO4 tech—enough to power a home’s daily appliances, from TVs and refrigerators to air conditioners. The long-lasting battery cells mean reliable storage for years, even with daily use.
Max solar input reaches 17,000W (HJ-H20-H10) and 25,500W (HJ-H25-H15), so it soaks up sunlight efficiently. With a wide 180-900V input range and dual MPPT, it keeps harvesting power even if panels are partially shaded—no more wasted sunlight.
Switches between grid-connected and off-grid in under 10ms. That means if the grid goes out, your lights, fridge, and Wi-Fi stay on—no blips, no interruptions to daily life.
Works with 380/400V three-phase setups, perfect for homes with big appliances. The HJ-H25-H15 puts out 15,000W steadily, handling everything from electric ovens to water heaters without breaking a sweat.
88% system efficiency means almost all the solar power you capture gets used—hardly any energy is lost. Over time, that adds up to lower bills and more value from your solar setup.
Works from -25°C (freezing cold) to 60°C (scorching heat). Whether you live in a snowy area or a hot climate, it keeps performing reliably.
Protects against voltage spikes, too much current, and short circuits. Plus, it’s IP65 rated—dustproof and water-resistant, so you can put it in the garage or even a covered outdoor spot.
50A charging and discharging means it can quickly store solar energy or send power out when you need it—great for sudden high-power uses, like firing up the AC on a hot day.
Check performance and adjust settings remotely using apps or computers (via RS485, Ethernet, etc.). See how much power you’re using, tweak storage, and stay on top of energy habits.
Stackable design lets you add more battery packs later. If you get an electric car or expand your home, just upgrade—no need to replace the whole system.
