Hello Freaks!!! How long?
Guys I've been working with On-Grid PV Systems, all kind of range Powers.
After a course last weekend when I saw some bad failures and when the DC electric arc starts . And this makes me thinks...
The general protection used for PV Systems on the DC side (solar modules) is main breaks and fuses for the strings, BUT the problem is that the maximum operation current is only 10% below the short circuit. So when the main breaks or the fuses will trip? It will be hard to trip and the failure will keep until the sun goes down
There is some other protection for it?
