An essential part of any solar power system, solar inverters convert direct current (DC) power produced by photovoltaic solar panels into alternating current (AC) electricity to power appliances and devices at home and in businesses.
“There are various factors that can cause a solar inverter to catch fire,” notes van Niekerk. It can simply be the naturally high temperature of its operating environment, compounded by the equipment generating heat as it inverts and transforms high-voltage electricity.
Potential short-circuits can also be caused by a lack of adequate maintenance and management, improper installation, poor quality equipment, or vegetation, plant debris and even small animals and insects finding their way into equipment.
Grid-tied solar systems are exposed to inrush current when the power is restored after load shedding that can cause damage or fires, so it is important to have the system designed and signed off by a registered electrical engineer.
“Any failed component that short-circuits can result in a fire that spreads throughout the inverter, causing a domino effect,” highlights van Niekerk. Here automatic fire suppression is important to quickly detect and suppress a fire so the inverter is offline before the fire can spread to other components. This reduces the impact of any fire and prevents damage to other equipment and the surrounding area.
The following general safety tips are recommended:
“Fires will happen,” says van Niekerk. Therefore, it is important to prepare for the worst-case scenario by understanding the fire risks, how to best mitigate those risk factors, and then lastly how to manage a solar inverter fire.
