Fire on new PV350 Solar Panel

Has anyone experienced the solar panel catching fire on first exposure to sunlight. I’ve purchased the BLUETTI PV350 to compliment my elite 200 and when I first opened it began smouldering then caught fire, I’m hoping it’s just a manufacturing defect. Are they reliable and could or does this happen frequently. Still trying to sort out a replacement as BLUETTI referred back to supplier yet supplier saying contact BLUETTI? Extremely frustrating!!
