Progressive Dynamics charger/converter for 2 Trojan T-105’s

My trailer came with a basic charger/converter and cheap 12V battery. Want to install 2 T-105’s AGM’s. I assume the factory charger/converter won’t be enough to charge the Trojans correctly....

Just keep the panel Voc below the controller Vmax and you are fine.

My controller is 150v max and the panels are maybe 40 Voc so three in series is under 120 volts. Vmp is about 30 volts so it mostly operates at about 90 volts input to the controller. Be very careful of safety of anything above 40 volts.
