<div dir="auto">Lorenzo<div dir="auto">You might want to look at relocating the inverter(s) closer to the meter instead of the array, one reason is even if there is some line loss at full power its less as the voltage goes up and the inverter does not see the line resistance that can cause high voltage issues at the inverter. Some engineers use more side of peak performance than full power, this keeps wite size down and does not effect output</div><div dir="auto">Jerry</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sep 17, 2018 9:42 AM, "Lorenzo Ortiz" <<a href="mailto:lorenzo@cal-solar.com">lorenzo@cal-solar.com</a>> wrote:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">
