<p>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.</p><p>Chris </p><p>------- Original Message ------- On 4/6/2011 11:55 PM August Goers wrote:<br />Jesse -</p><div><br /></div><div>Did you happen to measure the array voltage when the problem was�occurring?
