    How are they wired, and how many, what charge regulator (Charge controller?)

    I worry you have  series wired into a PWM charge controller, or have too much current for the model charge controller... So as much information as possible please.

    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Prosine 1800 and Exeltech 1100, 660 ah 24v ForkLift battery. Off grid for @16 of last 17 years. Assorted other systems, and to many panels in the closet to not do

    Do you have loose connections, water/humidty caused corrosion? Using any Aluminum wiring?

    I have seen fine copper wire that seems to corrode much worse that solid or course stranded copper wire (especially over time and higher temperatures)...
