How to prevent electrical fires in a distributed PV system?

In a typical small distributed PV system structure, electrical fires are mainly caused by DC arc. It is necessary to take comprehensive measures such as rapid shutdown technology and intelligent arc fault detection to improve the safety of distributed PV. Huawei FusionSolar launched the Smart Energy Controller (inverter) many years ago.

What happens if a PV inverter fires?

In the event of a fire, the PV rapid shutdown function can be automatically triggered by the disconnection of the inverter from the grid, interruption of communication with the remote emergency switch, or manually actuated by turning off the DC switches. As a result, firefighting measures can be taken immediately to minimize losses.

Do PV systems cause fires?

Therefore, the reliability of PV systems is very high, resulting in a low frequency of documented fires. However, when the numbers of existing and planned PV systems are considered, even with a very high reliability and low failure rate, the potential for PV fires remains significant.

Do building-integrated photovoltaics improve fire safety?

•The studied countries have different fire safety requirements for building elements. Building-integrated photovoltaics (BIPV), which can be integrated into the surface of a building (roof or facade), replacing conventional building materials, offer significant contributions to the achievement of net-zero energy buildings.

Are PV modules fire rated?

Since at the international level fire rating classifications of PV modules or panels have not been agreed, the 2016 version of the 61,730-2 standard states that PV modules mounted in or on buildings should comply with national building and construction regulations and the related requirements .
