The Deye SE-F12 12kWh Low Voltage Battery is a high-capacity lithium energy storage solution engineered for residential and commercial solar systems. Built with advanced LiFePO₄ (Lithium Iron Phosphate) technology, it delivers superior safety, long lifespan, and reliable performance for both off-grid and hybrid energy applications.
With a nominal energy capacity of approximately 12kWh (≈11.8kWh usable), the SE-F12 provides powerful and consistent backup energy, making it ideal for homes and businesses with higher power demands. Its 51.2V low-voltage architecture ensures safer operation and seamless compatibility with most hybrid inverters and solar systems.
Designed for flexibility and scalability, the SE-F12 supports parallel expansion of up to 32–64 units, allowing users to build large energy storage systems exceeding hundreds of kWh as demand grows.
