I am just hooking my system up here and for some reason I am getting no charge from my panels at all. I have them ran in series like The diagram I saw the Renogy team post. I have double and triple checked that the polarity isn’t reversed. I can’t understand why I wouldn’t be getting any solar to battery charge.

What about a blown fuse?? Are you getting any power from the panels checked with a meter??

check them separately, be sure a check a know source first to determine your meter is working, something like your vehicle battery.
generally they can be shorted up to 15A with no issue, that is how you measure them with a amp meter, you short them with the meter.

Okay. Checking them with my multi meter each one reads 22dc on their own

It seems that the solar panels aren’t being detected at all by the CC when I plug them in.

Okay. Checking them with my multi meter each one reads 22dc on their own that's good. so your 12v batts are connected in parallel to make one big 12v? controller connected to batteries and boots on? try hooking up just one panel.

Wired them in series and had 65 coming from them. Then I plugged my positive (with the inline fuse on it) and my negative in and when I test the end of those wires I get 0ac again.
Batteries are wired in parallel and working.

Controller is connected to the battery and the load is operational. Just not receiving current from the panels

So with the batteries hooked to the CC without the panels the CC comes on? You say your getting power from each panel but nothing when they are all hooked together at the CC?? Is that right??
If so I'd say your CC is bad....

Disconnect everything from the batteries and reconnect, making sure you connect the charge controller to the batteries BEFORE you connect the solar panels.

Batteries are wired in parallel and working. Does the top PV light turn on (white light)? If not we would recommend checking for continuity from the inline fuse to determine if that's what's preventing a connection. -Renogy Team
