I agree this is the place to start. Can you get the subarray/array configuration? It will either confirm or eliminate that the configuration is the problem.

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.

Wrenches,
I've been working on a sunny boy 1800 with some problems. There is no manual and SMA website does not have it available. �I need to watch the lights on the inverter to find the problem, but I'm not there now and I can't get this off my mind, so I will ask the esteemed members of this list.
When it's cloudy, the inverter comes on and loads the array. I can watch the sunny keeper watts reading rise until it get around 1000w and full sun hits the array. �Once full sun hits the array, the inverter drops out. �It did it three times to me today, and the inverter will not come on during full sun. Grid volts and hz are okay durning this.
I know it's impossible to troubleshoot like this, but anyone deal with problems like this?
Thanks for the help!
