Deye 5.12 kWh Lithium Battery 48V

The sun doesn’t shine 24/7, but your home still needs electricity after dark. The Deye 5.12 kWh lithium battery bridges that gap, storing your solar energy during the day so you can use it whenever you want—evening, night, or during those unexpected power outages.

Energy Storage That Actually Makes Sense

With 5.12 kilowatt-hours of usable capacity, this battery gives you real backup power for the things that matter. Keep your lights on, your fridge running, and your Wi-Fi connected. It’s enough storage to power essential appliances through the night or provide backup during grid failures, without the noise and fuel costs of a generator.

Built to Last, Built to Be Safe

This isn’t some cheap battery that degrades after a year. The Deye uses LiFePO4 (lithium iron phosphate) chemistry—the safest, most stable lithium technology available. You’re looking at thousands of charge cycles, which translates to years of reliable service. Plus, the advanced Battery Management System constantly monitors temperature, voltage, and current to keep everything running safely and efficiently.

Stack Them Up for More Power

One battery not enough? No worries. The modular design lets you stack multiple units together to scale your energy storage as your needs grow. Start with one 5.12 kWh unit and add more later—up to several batteries in parallel—without replacing your entire system. It’s like building blocks for your energy independence.

Plug and Play Simplicity

The 48V architecture works seamlessly with most modern solar inverters and hybrid systems. Whether you’re building a new solar setup or adding battery storage to an existing system, the Deye integrates smoothly. The compact, wall-mountable design saves floor space and looks cleaner than bulky generator setups.

Perfect For:

• Residential solar energy systems
• Off-grid and hybrid installations
• Backup power for homes and small businesses
• Load shifting to reduce electricity bills
• Areas with unreliable grid power
