Jesse - Did you happen to measure the array voltage when the problem was occurring? I ran into a sort of similar issue to this where the string voltage was just a little too low and once the panels warmed up they would drop out of MPP range. Just a thought. Any idea what the string configuration is?
Also, this might be a link to your manual, good 'ole Google: http://www.kyocerasolar.com/pdf/specsheets/sb1800_owner.pdf And the spec sheet: http://152.1.103.103/GRIDc/components/SunnyBoy1800spec.pdf -August On Wed, Apr 6, 2011 at 4:41 PM, Jesse Dahl <dahlso...@gmail.com> wrote: > Wrenches, > > I've been working on a sunny boy 1800 with some problems.
