  1. Thanks
    BritishRacingGreen reacted to Coulomb for a file, Axpert and Infinisolar capacitor modification.pdf   
    I found this in my downloads folder recently, and it seems to be one answer for a number of problems, such as parts of the display flickering intermittently, especially models with the colour display and round LED ring. In a separate .docx document (not attached here), it says:
    [ Edit: Axpert MKS IV models (under their various names) should have this modification provided from the factory from about August 2022, according to one reseller. ]
    [ Edit 2: See also this post for a way to rearrange the wires to the MPPT inductor; it worked for at least one poster. ]
    I note that the capacitor part number (a Voltronic part number, you can't order from an electronics retailer with this number) mentioned above is different to that of the PDF in this download, so I may be conflating fixed. However, the rest of the .docx document has almost verbatim the same text. The docx document mentions an 18μF 600 VDC capacitor, but that would be much larger than the one pictured. If you don't order the part from your supplier, I suggest about a 2.2μF 600 VDC X2 class polyester film capacitor.
    DANGER!
    PV voltage on these models is lethal! The charge on the capacitor will persist at a lethal level possibly for hours even after the PV is isolated, so ALWAYS test first with a decent multimeter. Do not touch the terminals if the voltage is above 50 VDC. If you don't know electronics, DO NOT ATTEMPT THIS!
    This modification may make your inverter significantly more dangerous to work on. If you are in the habit of working on the PV wiring, you might want to reconsider performing this modification. Maybe the circuitry will quickly discharge the capacitor, I don't know as I don't own one of these models.
    DANGER!
    There is also talk of a metal shield, and possibly an inductor, but I can't quickly find this thread. Hopefully, this will help someone, or at least point them towards a solution.
