Is that an amount of shade that would cause insufficient current for charging?

The shading is around a quarter of total panel surface usually. The shade is from tall alder trees, so it's splotchy. Once in a while one or even two of the panels will be in full sun.

All right, I'm going to hop up on the roof and switch my setup to 2s2p today. I'll report what kind of numbers I see. Thank you for your help!

It's mppt. The battery isn't full as far as I can tell, I've taken voltage readings at battery, and as soon as the sun goes down the battery drops down to a low soc. The DC amp clamp sounds like a good idea, as I blew the fuse on my 10a multimeter earlier.

Ok. That makes sense. I gather that the battery voltage will show in the 14v range during a bulk charge and the 13v range during a float charge, which will be different than both the input voltage from the panels and controller. What I can't figure out is why the controller won't charge the...

My setup on my off grid RV is 4 x 100w renogy panels, connected in parallel Rover 40a mppt controller Single 12v sealed battery There is some moderate shading on the panels at any given time, but typically at least one panel is in full sun. I've taken readings at the terminal ends of the...
