Description

Product Description
The Deye 18 kW hybrid inverter is a versatile energy conversion unit that combines solar PV input, battery storage, and grid interaction. It supports low-voltage (48 V) lithium-ion or lead-acid battery systems with high charging and discharging currents for strong backup performance. The inverter features multiple MPPT trackers to maximise solar generation, intelligent air cooling, IP65 protection for indoor/outdoor installation, and advanced monitoring and communication interfaces. It is scalable via parallel operation for larger systems, supports AC coupling and generator charging, and includes robust safety and protection features to ensure reliable performance.
