<html><body><div style="color:#000; background-color:#fff; font-family:arial, helvetica, sans-serif;font-size:12pt"><div><span>Hi </span></div><div><span>I have a system in operation since 2003 using 13 paralleled Outback MX 60 CC and I have measured over 600 Amps at 48 Volts.on the common bus. Outback and I replaced the fans in the MX 60s but we have had no failures. This power is converted to 60 hZ using 12 Outback inverters, I have had an inverter trip off on the DC side just the other day and I will check it out this comming week but no problems. </span></div><div><span>DT</span></div><div><br></div><div style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"><div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"><font size="2" face="Arial"><div style="margin: 5px 0px; padding: 0px; border: 1px solid rgb(204, 204, 204); height: 0px; line-height: 0; font-size: 0px;" class="hr"
