Deye 5.12kWh High Voltage Lithium Battery provides safe, reliable, and efficient energy storage for residential and commercial solar systems. With LiFePO₄ cells, intelligent BMS, and a 0.5C discharge rate, it ensures long cycle life, scalable modular design, and maximizes solar energy usage for backup power and load management.
The Deye 5.12kWh High Voltage Battery (0.5C) is a high‑voltage lithium battery module that stores electrical energy for later use, maximizing solar self‑consumption and providing power backup during outages. With a nominal energy capacity of 5.12 kWh, it’s ideal for hybrid and high‑voltage DC solar systems. It supports a 0.5C discharge rate, meaning the battery can be safely discharged at half its capacity (≈50 A) over one hour for stable performance.
This battery is perfect for:
Homeowners wanting efficient solar energy storage
Commercial properties reducing reliance on the grid
Solar installers building hybrid or high‑voltage systems
Properties in areas with frequent power outages
Users who want scalable, long‑lasting renewable energy storage
Whether you’re optimizing solar use or building a resilient energy system, this battery delivers safe, long‑lasting power storage.
