Constant batt voltage loss

I have had my unit for 1 month now and batt voltage has been steadily on the decline. I have relocated twice to work around the tree line on my property. But even on sunny days I see no evidence of voltage increase. Can someone have a look at my data and provide comment.

You should probably open a ticket with support for a definitive analysis. Looking at your data, I don’t think you are getting enough direct sunlight to charge the batteries. Look at the Solar Radiation graph. It rarely gets into the range where charging should start (typically above 300 W/m2).

I have a challenging site with a lot of trees. I had to relocate my unit to a spot where it got direct sunlight for 5 or 6 hours to get any meaningful charging.
