Set up the MPP and connected first string of PV: 2s1p , 48.7 v and 355 watts each panel.
Am I missing something? MPP shows no v and no watts.
Granted, it is my first time using MC4 connectors; and I did not get voltage readings off of each panel prior to install; my bad. The crimping is just okay ; but , the Male and female MC4 connectors are new to me.
Anyway, now I need to test the connections!
Now, the MC4 connectors warn: " do not discount during load "; and, I realize no one would recommend disconnecting during load ( plausible deniability) ; yet, if I did test at the panels is it known to be very hazardous or have people been known to disconnect these for testing?
Furthermore, did I miss something concerning plugging in panels for the first time?
Also, I had the panels out in the yard for a couple days befor I wired them. Does this hurt the panels?
Thanks
