Have You Heard About The New Solar Inverters Coming To The Market To Prevent Fires In Solar Energy Systems? This Innovation Is Here To Bring Much More Safety And Peace Of Mind For Those Investing In Clean Energy.
There has been a lot of news about photovoltaic systems catching fire lately. This happens mainly due to poorly done installations and unqualified professionals in the solar energy sector. But don’t worry! The new generation of solar inverters is arriving in full force to solve this issue.
One of the biggest culprits of fires in solar energy systems is the electric arc. Simplifying, an electric arc occurs when there is a failure in the connection between two conductors, causing sparks and, in more serious cases, fire. These arcs can arise at various points in the installation, such as string connections, junction boxes, and even in the photovoltaic modules themselves.
The New Generation Of Solar Inverters For Solar Energy
To combat these problems, the new solar inverters come equipped with a device called AFCI (Arc Fault Circuit Interrupter). This equipment is a true hero in fire prevention, as it detects and interrupts electric arcs before they can cause any damage.

Inmetro Ordinance 515 of 2023
An important update is that, starting from Inmetro Ordinance 515 of 2023, all manufacturers of inverters and microinverters with voltage above 120V and current over 20A must include the AFCI in their products. For equipment with smaller specifications, protection may be waived, as long as the equipment control ensures the extinction of electric arcs.
How Does The AFCI Work?
The AFCI is basically a switch with an electronic circuit that detects the formation of the electric arc. When the arc occurs, the electric current has a specific waveform pattern, which is identified by the AFCI, which then interrupts the current flow, eliminating the arc. This brings much more safety to solar energy systems.
When Will These New Inverters Be Available?
Manufacturers have until December 2024 to adapt to this new regulation. However, many are already putting solar inverters with the included AFCI on the market. And the good news is that, even with this new technology, the prices of the equipment are not expected to rise, due to strong competition among manufacturers.
So, everyone, did you like this news? The new solar inverters promise to bring much more safety and avoid those scares with fires in photovoltaic systems. It is an important advancement for those already using or thinking of investing in solar energy.
