    We feed into one of Shakopee’s substations and our site station service electrical feed is back thru the same BAO’s when we aren’t generating.  The last 3 months we have had periodic site power losses, the BAA breakers opening up to the high side of the 480V transformers.  Wartsila maintains that it is the 125DCv system that is at fault.  We have checked the batteries and charger and they seem to be functioning correctly.  Has anyone had any experiances resembling this issue?  Clould the issue be in the CFA901 panel?
