Just completed our first travel trailer trip of the season. Towards the end of each travel day we got multiple notifications from the SmartSolar Charger of high input voltage. This occurred on 3 of our 5 travel days - all between 5-8 hrs long. There were multiple days of running solar only at our various campsites with no issues. Would the issue be with the DC-DC charger overcharging from our truck? This is our 2nd camping season with the Victron system - zero issues last year.
