So, what brands of SPD do you buy that are DIN mount?
Second related question - combiner box - why is it nearly all of them made from plastic verse metal? I assume cost has a lot to do with it.
Next, do you fuse each line from the strings then connect a SPD to each string, or just on the breaker? Or do you use breakers instead of fuse holders?
