I've  run an FM80 charge controller for a few years now. Recently, I've notice two logging days where nothing was recorded; every category reads zero (max/min volts amps etc).
Any ideas what may have caused this and if it's something to be concerned about?

    @706jim, it would probably best for you if you post this over at the outback power forum. In the flexmax threads.

    Can't seem to get this forum on line anymore. Otherwise I agree with you.

    Logging as to the Mate3 SD card or to OpticsRE?

    BTW, forum.outbackpower.com is working  just fine.
