Description

Deye AI-W5.1-B - 25.6kWh Low-Voltage Battery Storage Set – your ultimate solution for total independence from large utility providers. With a massive 25.6 kilowatt-hour capacity, this high-end system stores the valuable electricity from your solar array in enormous quantities. It's the perfect choice for demanding households with very high power needs, large heat pumps, or multiple electric vehicles. Thanks to its well-thought-out tower design, the entire set can be installed in your home in a remarkably space-saving way despite its massive output. The completely cobalt-free lithium iron phosphate technology (LiFePO4) guarantees you the highest fire safety and an extremely long service life.

The Strongest Benefits for Your Home

Effortless installation: Forget error-prone cable clutter. Thanks to the revolutionary plug-in system, the five battery modules are simply and securely stacked on top of each other. The connection is made completely automatically via integrated plug contacts, which greatly simplifies setup.
Intelligent protection: The smart battery management system (BMS) works completely silently in the background. It monitors every single battery cell around the clock and fully automatically protects your valuable investment from overheating, overcharging, or harmful deep discharge.
Future-proof and flexible: Even at this impressive size, the system remains modular. You can perfectly tailor the setup to your life and benefit from a system that's well-equipped for the future of energy supply.

Smart Control for Your Electricity Costs

Save real money permanently thanks to clever technology working in the background. This powerful home battery storage set intelligently ensures that your valuable solar power isn't fed into the public grid for just a few cents, but is instead available exactly when you need it in your own home – even on long winter evenings. Another extremely important safety feature is blackout protection: if the power in the public grid ever fails, your system's integrated backup power function kicks in. Within milliseconds, the system switches over so that heating, refrigerators, routers, and lights keep running without any noticeable interruption. You practically won't even notice the power outage.
