Deye SUN-20K-G04P3

Deye SUN-20K-G04 is a high-performance grid-tied inverter created for the efficient conversion of solar energy into stable electricity for residential and commercial facilities.


Description

Deye SUN-20K-G04 is a high-performance grid-tied inverter created for the efficient conversion of solar energy into stable electricity for residential and commercial facilities. Thanks to its 20 kW output, support for three-phase grids and modern optimisation technologies, it delivers the maximum return from a solar power plant.

The inverter uses advanced technology for converting direct current into alternating current, which makes it possible to minimise energy losses and achieve a high level of efficiency. The 20 kW output makes it the optimal solution for facilities with medium and high levels of electricity consumption.

A three-phase connection ensures an even distribution of the load, increasing the stability and efficiency of the entire system.

The inverter is equipped with two independent MPPT trackers, which make it possible to:

  • optimise the operation of solar panels in various conditions
  • reduce losses during partial shading
  • increase the overall performance of the system

This is especially relevant for complex roofs or installations with different panel orientations.

The built-in Wi-Fi module provides a permanent connection to the system and makes it possible to control the inverter remotely through a mobile application or a web interface. You get access to the key parameters in real time:

  • energy generation
  • current load
  • system status
  • operating history

This simplifies servicing and makes it possible to react quickly to any changes.

The inverter is equipped with an intuitive LCD display that shows all the main operating indicators. A simple menu and clear navigation make it possible to quickly configure the system and monitor its efficiency without unnecessary complications.

Deye SUN-20K-G04 complies with modern safety standards and is equipped with a comprehensive protection system:

  • against overvoltage
  • overcurrent
  • overheating
  • possible system malfunctions

High-quality components and a robust design ensure stable operation even in demanding environmental conditions.

Deye SUN-20K-G04 is a modern inverter that combines power, smart technology and reliability. It makes it possible to use solar energy as efficiently as possible, reduce electricity costs and ensure stable operation of your energy system for many years to come.
