    I have had CZ2 (8 uf capacitor) go bad in two of 8 units. Dont 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

    bad (leaky)CZ2 causes no battery charging. I never did figure out what causes the Outputs to chatter.
    I have 8 of the controllers and only 2 of them have the problem of chattering output.
    the part numbers on the boards are the same on the two that chatter.
    I only use the outputs on 2 of the controllers, so I just put the ones that chatter where I don't use the outputs.
    I think the chattering problem is in the programing of the chip on the ones I have.
    Be carefull testing around D3 the opto isolator , I toasted the PLC chip P3 I think I touched the scope ground between the chip ground and the solar panel negative NOT Sure but b carefull working in that area
