Using 3x100 watt panels wired in parallel feeding two different PWM 30A controllers charging two different batter banks ??

I purchased a used class b motorhome that has 2x100AH lithium batteries for the coach and a single 12 volt AGM battery for the dodge promaster 3500 chassis.  It has 3x100 watt roof mounted Renogy panels wired in parallel using branching connectors to feed a single pair of wire which was then split downstream to feed two different PWM controllers with one charging the chassis battery and the other feeding the coach battery bank.


does this configuration cause any other problems than being inefficient use of the 3 panels for the controllers or batteries??
