Thanks smkettner! Advice was not what I was actually looking for. It was the use of a 285watt panel. It does appear from the video that the controller is a 12/24V model not a 48V model.
Are you contemplating using a 48V charging system and 48V capable inverters in an RV?
You do know that you don't need a controller rated to 48V output to charge a battery with 45V input?
I'm with smkettner on the value of that video. The author thinks that he is at a positive charge/usage rate when the controller shows a 9.5 amp discharge and a 5.4 amp charge supply. Additionally, if that is all he is getting out of the 285W panel, he is wasting a lot of charge. He should have an MPPT charge controller with that module.
