What is an inverter?

A solar inverter is the "heart" of the solar energy system. Its reliability and safety are directly related to disrupted operation of the solar power plant, its conversion efficiency is directly affected on the efficiency of electricity production, and its lifetime is directly related to the lifetime of the photovoltaic energy system. Therefore, it is necessary to understand that the inverter is a very important element in the entire construction.

What is the role of an inverter?

Inverter is power electronics, which connects solar panels with electrical grid. Its main function is direct current conversion, generated by solar cells, into alternating current, which we need for everyday use.

Direct current cannot be used in everyday life. Household appliances cannot be powered by DC electricity, so for the widespread use of solar electricity in our daily lives an inverter, which can convert direct current into alternating current is indispensable.

The inverter not only has the function of converting direct current to alternating current, but also has the function of maximizing solar cell performance, system modulation and maintenance, peak power tracking and control, direct current grounding detection function, etc.


Fox inverters are designed to provide maximum performance, efficiency, reliability and longevity. The quality of the components directly affects the life of the product, which is why we only use components of the highest quality from the world's leading manufacturers.

What is the difference between inverter and hybrid inverter?

An inverter is an electrical device that converts direct current (DC) to alternating current (AC). Inverters are commonly used in renewable energy systems, such as solar power systems, to convert DC power generated by solar panels into AC power that can be used to power homes and buildings.

A hybrid inverter is a type of inverter designed to work with renewable energy sources, such as solar energy, and traditional sources of energy, such as the power grid. A hybrid inverter is basically a combination of inverter, charge controller and grid connection function.

The main difference between an inverter and a hybrid inverter is that a hybrid inverter can work with both renewable and traditional energy sources, while an inverter can only work with renewable energy sources.

three-phase network inverters - converters


3 ~ 25kW

H3 - AC3 

5-12 kW


75 ~110kW

The inverters of the T series (G3) are intended for 3-phase domestic and small commercial installations and boast exceptional performance. 3-phase inverters of the T series (G3) have power from 3 kW to 25 kW.

The functions of a hybrid inverter:

  • Energy storage capacity: storing excess energy generated by renewable sources for later use.
  • Network connection function: to connect the system to the electricity grid and sell excess energy back to the grid.
  • Automatic switching - integrated EPS (Emergency Power Supply) function: to switch between renewable and traditional energy sources as needed. The EPS function switches in 0.02 seconds, which ensures the uninterrupted operation of devices in the house. 
  • Monitoring and control: to monitor and control the system via mobile application or web portal.
  • Hybrid inverters are ideal for homes or buildings that want to use renewables as also traditional sources of energy and want to be able to store the excess of energy in electricity storage units (battery).
  • They provide greater flexibility and reliability than traditional inverters, as they can automatically switch between different energy sources and thus ensure a steady supply of electricity.
