EB55 not charging

Hey guys I just got my EB55 and after draining it down completely, it turns on when I plug in the solar panels (2 renogy 100w) but does not charge! WTF? Any ideas?
(I like to use solar panels only and they are working fine with my ac200p )

12 volt panels ?/parallel or series ?

12 volt panels in series , worked to charge the unit

The EB55 can only accept an open circuit voltage of 28v, your Renogy’s are probably over 40v in series. Switch to parallel and it should work.
