    Default How many cables run from the panel array to the inverter?

    I am setting up a shed roof for 20 panels and want to install an entry point that is flashed from the ridge capping.
    I live in a very high rainfall area and refuse to put one of those rubber pipe flashing boots on my roof. I need to know how many cables run from the panels to the inverter for sizing of the box. Can anyone help?

    Are these for inverter use or just battery charging?

    20 panels might be just over 5kW, maybe!! Usually two strings are run, any more and efficiency drops. I'd ring the installer, I drilled a 40mm hole in a tile for mine.

    Above should be correct which will fit in one 25mm conduit easily.
