The Importance of a Solar Inverter

When people think about solar power, the first thing they think about is the large panels fitted to the roof. However, the large sheets are not the only thing you need to convert the sun’s energy into power for the building. For the power of the sun to be used by the various appliances in your home, it must go through an important compnent of the solar system – the solar inverter.

An inverter is an absolute MUST for a solar system, as it is responsible for the conversion of power collected by the panels into a current that is applicable for use in your home. To understand the importance of a solar inverter, you must first understand the entire solar process.



  • The process begins with the panels. Comprised of a silicon material that converts the sun’s energy into electrical power, the panels collect the energy from the sun.
  • The panels collect the power throughout the daylight hours, and continuously produce the direct current (DC) to be sent elsewhere for conversion.
  • The individual panels then combine the collected power and send the DC to the inverter for an essential part of the process.



  • In the form of a small box, some inverters record the efficiency of the panels, giving you a specific gauge on how much power you collect from the system.
  • The inverter, which in the case of a central inverter is often fixed out of the way on the side of a business or home, receives the DC from the panels.
  • The vast majority of home appliances such as TVs, fridges and lights run off of alternating current (AC). So, the solar inverter’s role is to transform the DC into the necessary AC for everyday use in the home.
  • Some systems use microinverters rather than a single central inverter, which are fixed to the underside of each panel, and collect and transform DC and convert this power to an alternating current. However, these options are more expensive.



  • Once the inverter creates the correct power input, it sends it to the fusebox to be delivered to the building efficiently.
  • When the AC is received by the switchboard, it is delivered to the home to power all of the appliances as required.
  • From the fusebox, excess power is either sent to a battery storage system or back into the grid, depending on your usage and system set-up, this will vary.


It is clear that the inverter is crucial for the conversion of the energy collected from the panels to a power source that can be used continuously in your home. The solar inverter works as a middleman, and without it, the power collected by the panels would be worthless.
