Still no voltage...wiring wrong?

Not sure if right but
If I turn my meter to 2V = .251 and 20V = .20

Is that what you are looking for?
 
The solar wiring feeding the growatt are putting out less than a volt?

One or more got fried, and the diode is shorted...
Time to go up on the roof disconnect every wire, and measure what if anything is putting out power.
 
So I check each panel by putting the meter on and in the male and female leads from the panel..what approximate number should I see if working?
 
Full sun has passed as it is almost 6 here but I measured 3 panels.

I set my multimeter to 200v and got two panels to read 33 and one panel 28. Does it sound like those three panels are functional?

Thank you for the help
 
And yes Supervstech when I put my multimeter to 200v I get 0 when touching the PV wire to my growatt

I suspect your MC4 adapters. Check the wires before them.
Hook up only one set of series panels then check the other one.

Thank you MBR I did have two MC 4 connectors that were faulty. Now I have 100volts going to my 48v Growatt but I am still not getting anything for PV watts.

I have set my growatt to Solar first and my solar panels do get direct sun for 2-3 hours. I in the process of trimming the tree in my back yard so the panels get more
