6 FAQs about [Photovoltaic combiner box accident]
What causes a damaged combiner box?
FIGURE 7. Damaged combiner box by fire . PV modules may also suffering from physical damages. For instance, the cracks of PV modules are caused by the stress or pressure. If the welding area of the module is too small, it will easily cause the panel to rupture over a long time. Cracking is the main cause of fault of PV modules.
What is a combiner box in a photovoltaic system?
In a photovoltaic system, a combiner box acts as a central hub that consolidates and manages the direct current (DC) output of multiple solar panels. Its main purpose is to simplify the wiring structure, enhance system security and simplify maintenance procedures.
Can DC arcing cause a PV plant fire?
The majority of PV plant fire accidents are caused by DC arcing. The following figure shows a fire accident in a PV plant in the United States, with the subsequent investigation finding that the component overheated due to two arcs, causing the combiner box to set on fire.
How to reduce the risk of PV fire accident?
In order to reduce the probability of PV fire accident, there are technical specifications to comply. Firstly, the PV module needs to pass the UL 790 “Safety Standard for Roofing Material Fire Test” combustion and flame spread test. Secondly, the inverter should be designed without fuses to avoid fire caused by DC side faults.
Can a PV system cause a fire?
The fire service can be subject to electric shock when fighting a fire due to the presence of high voltage and current. During the course of fire on a building with a PV system, DC cable insulation can melt and cause a DC arc flash. The same may occur if a PV system is disconnected incorrectly.
What causes a PV module to break?
PV modules may also suffering from physical damages. For instance, the cracks of PV modules are caused by the stress or pressure. If the welding area of the module is too small, it will easily cause the panel to rupture over a long time. Cracking is the main cause of fault of PV modules.
