I finished a new Victron 5KVA Easysolar installation connected to an ET112 Grid meter. The system will run perfectly for a few hours and then looses communication to the ET112 and causes the Inverter to go into a Passthru mode. I then need to reboot the CCGX that will solve the problem untill it happens again after anything from a few minutes to a couple of hours. It will also always happens after a grid failure (load shedding) when the power is restored. I replaced the ET112 grid meter as well as the victron rs485 to usb cable which didn't solve the problem. I re-routed the the rs485 to usb cable and did the software upgrade again without any success. I've done many similar installations in the past and never experienced this issue. Any suggestions to solve this issue.
