I have an MX60 (4 years old) that recently started going into sleep mode for a couple seconds, then wake up, and then will settle back into MPPT. From sleep to MPPT takes about 30 seconds. The frequency of this has increased to several times per hour. I figure I'm losing an hour of charging per day. I talked to Outback support & tried a few things they suggested without success. Anybody else experienced this??
