    Hi All,

    So my p10 matrix stopped working and this morning upon pulling it apart, many of the panels have let out the magic smoke. As to why is a question I am still looking at.

    I have a couple of spares but not enough to repair the matrix.

    Does anyone have any spare P10 panels they won't be using this season?

    Thanks!
    Daryl

    OK, so further investigation shows that the buck that was running them now puts out 7v.

    That has fried all 12 panels in the matrix.

    The weather recently and the following specs may have been part of the reason.

    7. working temperature: (-40 °C-80°C) when it is more than 40°C,please make lower power, or enhance heat dissipation
    8. full load temperature rise: 50°C

    I don't think I'd trust a module like that to output 25 Amps.

    Those P10 panels can draw up to 3 Amps each when driven well, so that's 36 Amps for 12 panels at full tilt.

    Maybe using one of those converters per 4 panels would have been better.

    Well I've learnt my lesson. I have a heap of those bucks running at ~16A no worries (touch wood).

    I will add a 5v PSU to the back of this P10 matrix when I re-make it.

    That's how I built mine this year...
    I used a rainproof 5V power supply mounted outside on the back and ran power to inside on enclosure.
    The +v and -v then go to 2 separate terminal blocks. Then the +v going to each panel has an in-line fuse.
    Ron's controller gets its 5v from the terminal blocks as well.
    Now the real problem.....
    Wife likes it so much (only a 3X2 panel), she wants another.......3 or 4 times its size.
    :eek:
