Mac, That outs not the typical type of failure in my experience. Usually, an optimize failure just takes out the one module's production, although I have seen a couple of failures that either disable the whole string or even the inverter. If you establish communications with the SE monitoring portal, then you can get error warnings that would appraise you of a variety of problems, including any production issues. Howie
