I also just recently purchased a Zamp 180w portable suitcase. It works great!

1. Is it possible to replace the Sunexplorer II charge controller with 1 Victron controller, AND have the victron monitor both the rooftop 90w panel and the Zamp 180w suitcase panels (the latter would need the built in charger disabled)?

My goal is to monitor usage/charge for all panels combined, from the App.

2. Both panels charge the batteries quickly and keep them charged during the day, however ~4 hours after sundown my battery is showing 12.1-11.8 with only running a few LED lights and the fridge. Would 1 lithium battery give me more capacity than 2 AGM batteries?

thanks in advance...I'm still learning.

That would take a lot of wiring. It would be much easier, but a little more expensive, to buy 2 Victrons and replace the onboard controller and the zamp controller on the suitcase.
