hi i recently bought a series of midnite solar products for an off grid system (combiner box,classic 150 and spds)however after i still have a question on the range of protection the offers.the reason i am asking this is because the ac side of the system was protected previously by delta lighting arrester which had to abe used also with a surge capacitor so my question is does midnite spd offer the two types of surges as mentioned by delta .
you should be able to replace all of that crap with the midnite spd. if you want to, you could even employ all 3, but only the midnite spd is really needed.
thanks i was hoping its like that
