I have had CZ2 (8 uf capacitor) go bad in two of 8 units. Don't toss them. The capacitor starts leaking at higher temps and stops charging. I replaced them with a 10uf 16v electrolytic and no problems.

In 3 of the units with Part#s 1211V3.0 the outputs chatter on and off when they turn off.
the other units with part#s USB4.0A and USB6.0 don't have the problem.

Anyone else noticed this problem? And know of a fix.Solar80_MainBoard_1211V3.0.JPG Solar80_Ours.jpg
