I recently Upgraded to SmartSolar Charger MPPT 100/50 for my RV setup. I presently have 3- 160W (8.38A) Flex panels run in parallel to the charger (based on advice for my previous 30A PWM charge controller).
I am looking to add a 4th panel to the setup and more storage capacity. my question is wether I should add it in Parallel as well or should i rewire for series or series/parallel for this new controller? attached is previous wiring Diagram with old charge controller for reference.
Any advice would be greatly appreciated.
