Hi Ryan so glad you were doing this I think there's a whole lot of 🐍 oil as you point out in the industry of these shielding devices. I used the midnight ssd myself. By the way I hope your cummins engine comes back okay I have one also. Can't wait to see what's inside that EMP shield. Thank you for doing this.

The fast speed of the emp shield is for the e1 pulse. Nuclear emp has three separate voltage spikes of varying speeds. E1,E2 and E3. E1 is nuclear only, solar flares don’t have it. It’s a millisecond pulse that most equipment don’t actually block because of the speed. Only a handful of commercially available TVS diodes will. Don’t know if the EMP shield actually has it but it would make it nuclear emp proof of it did. After that it just depends on the strength of the emp and the length of wire. A long enough wire and it doesn’t matter if it blocks 100k volts, the voltage will climb very high. E2 is more like a traditional lightning strike and most standard commercial Lightning arresters will block it. I am a bit fuzzy on E3 but I think it’s more current and tends to trip regular breakers and fuses. Longer pulse.

A nano-second is 1000 times shorter than a micro-second

Could 2 Midnight Solar SPD be used, one on each 120v line of a 240v system, and the commons from each SPD combined? Cheaper way to protect the 240v common than the empshield? Wow... That doesn't even make sense to me... What I want to do is protect 3 strings of 240v micro-inverters (that combine to feed a long 240v line to the main), from any surge from the grid or from some malfunctioning appliance on that line. The 240v feed from the inverters is on common but is of course bonded to ground at the main.

Yes 2 would work perfect, Say red of SPD1 to L1, Black of SPD1 to Neutral. Red of SPD2 to L2 and then you have the black it could also go to Neutral or either of the L1 or L2

So I was wondering. My solar array is about 40' from my controller (MN3024) and e panel (MNE200DIY). At the solar array I'm going to install the MNPV3 combiner box. Both the e panel and the combiner box are set up to allow a surge protector. In order to keep the e panel as clutter free as I can, I was going to install the surge protector at the combiner box close to the array thinking it shouldn't make a difference, while still protecting the controller. I guess I'm just looking for confirmation that my train is correct? Thanks again ...

Personally I would put it at the 3024, 40ft is a long antenna in a close strike

@@aroundthehomesteadwithsuer3497 makes sense, thanks again..

Well of COURSE the Delta is going to allow a 10KV delta. It's a "Delta" !
