Deye batteries are lithium iron phosphate (LiFePO₄) energy storage units developed for the manufacturer's solar and hybrid energy systems, which ensure reliable, safe and long-term operation. Deye energy storage units are specifically optimized for the SUN series hybrid inverters, so the system can perfectly cooperate with solar production and the current energy demand of the household or business. The modular design allows for the parallel connection of multiple units, so even high-capacity (100+ kWh) energy storage systems can be created.

Deye batteries have a built-in BMS (Battery Management System) control that automatically monitors the temperature, voltage and state of charge of the cells, preventing overheating, overcharging or overdischarging. With LiFePO₄ technology, Deye batteries offer outstanding safety, thousands of charge cycles and minimal capacity loss. The intelligent control and hybrid compatibility make these batteries an ideal choice for residential, commercial and small industrial energy storage systems.
