    Wondering why're many people still building 12/24v system ?

    I have about the largest system that you would ever want to build in a 24v system. I have 4 Magnum ms4024 PAE stacked, for a 16kw system with 122kwh battery and 29kw array.

That way if it is overcast or bad weather I can ac couple one or both inverters alongside my three cc to make up what needed to fill my 120kwh...

    Upgrading Midnite Classic 150 to Magnum PT-100

    I have been a Magnum guy forever. I had 4 old inverters running and wanted back up's, being unsure about the (new) Mexico version, I pulled two old down and install the new to run under warranty in case of problems,

    Basic fusing question (maybe)

    If you follow Ben as I do your worried more about EMP or coronal mass I'm guessing. Do a search on EMP. Best thing to do is have a back up in a faraday cage.
