I had to go up to the farm the other day to get something out of the trailer, and as it hasn't been out since June, for our 3-week European trip. I had a look at the solar controllers while I was there.
It was a very dull day with light rain at about 3.30pm, so not much to stir the panels, but the battery sets were both sitting at 13.30V with nothing connected, all the lighting etc was disconnected after I pulled the fuses.
Later I had a look in the Mercedes to see what it was doing. 4.30 pm and very dull, the two battery sets were at 13.20V, both showing identical figures.
Looks like they are doing their job and the controllers are working well.
110ah + 55ah sealed batteries in the trailer, 2 sets of 2 80W panels and two Maximum Solar 20A MPPT controllers.
225AH + 225AH AGM batteries in the Mercedes, 2 sets of 2 100W panels and two more Maximum Solar MPPT controllers.
The two installations are 3+ years apart in age terms.
