Description

Deye AI-W5.1-B - 20.48kWh Low-Voltage Battery Storage Set – your powerhouse for absolute independence from rising electricity prices. With a gigantic capacity of 20.48 kilowatt-hours, this system reliably stores the valuable electricity generated by your solar system. It's the perfect choice for households with high power demand, those running a heat pump, or for charging electric cars overnight. Thanks to its sleek tower design, the entire set can be installed in your home in an extremely space-saving way despite its enormous capacity. The proven and completely cobalt-free lithium iron phosphate technology (LiFePO4) guarantees maximum fire safety and a particularly long service life for many years.

The Biggest Benefits for Your Home

Effortless installation: Thanks to the revolutionary plug-in system, the four battery modules are simply and securely stacked on top of each other. The connection is made fully automatically without error-prone cables and connectors, which makes assembly significantly easier and saves time.
Intelligent protection: The invisible but smart Battery Management System (BMS) monitors every single battery cell around the clock. It automatically protects your investment against overheating, overcharging, or harmful deep discharge.
Future-proof expandability: Even at this impressive size of over 20 kWh, the system remains flexible. You can easily add more battery modules to the tower if needed, should your energy demand grow further in the future.

Smart Control for Your Electricity Costs

Save 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 in your home exactly when you really need it. On cloudy days or at night, the huge battery storage supplies your home completely silently. Another extremely important safety feature: if the public grid power fails, your system's integrated backup power function kicks in. Within milliseconds, the system switches over, so refrigerators, routers, and lights keep running without interruption. You practically won't even notice the power outage and are always on the safe side.
