Operating Principle of the Deye SUN-18K-G05 WiFi Grid-Tied Inverter


Converting Solar Energy into the Electrical Grid


After solar panels collect energy, the inverter converts direct current (DC) into alternating current (AC) synchronized with the 220/380 V grid. This enables the facility to be powered or to feed energy into the public grid.

The Deye SUN-18K-G05 WiFi inverter is equipped with two MPPT trackers that independently monitor the maximum power points of each panel group. This increases efficiency even under partial shading or different panel orientations.

Built-in WiFi monitoring allows users to view performance, diagnostics, and parameters in real-time via a smartphone or PC. The device also features built-in safety functions, including protection against short circuits, overvoltage, and overheating.
