I'm setting up a campervan and actually I'm curious about electronics but still have a question about this problem.
I want to charge my AGM Battery mainly via solar. Therefore I've got the MPPT 100/20. Input is the Panel, Battery is the AGM and Load are all consumers.
Parallel to this I want to charge the battery (AGM) while driving an the weather is bad so I can be sure my battery is loaded. Therefore I'm using the Orion-TR 12-12-9 with a manual switch.
Actually everything should work, but I'm not sure about the fused inputs and outputs and the solar panel.
What do you think?
