Greetings all. New to the forum here and I am installing Sol-Ark 12K's which claim to have integrated "lightning protection" but I'm not sure that I fully trust this due to the fact that it states exceeding 500V PV source may damage the unit. As a second line of insurance I tried to find 500V SPD's but reputable manufacturers like Midnight Solar only have 300V or 600V models. Should I assume the unit is protected from the factory, install 600V Midnight Solar units, or go with the unknown brands of 500V units available? Any suggestions? Thanks in advance
