Adding a Renogy Solar Suitcase - Dedicated MPPT

Hi, Not a solar wiz here but hope to be..

Anyways - I currently have a meager system consisting of 3 200w panels over the davits in series connecting to a victron mppt 100/50..

Its very common on the hook / mooring I will not get sufficient charge to the AGM bank (3x250ah)..

I want to add a solar suitcase for to get some sun in the earlier part of the day. What I want to know is if I add a separate mppt will it matter what wattage the new panels are?

No, with a separate controller you can have any panels you want.

I have something similar on my boat. My "fixed setup" is two 200 watt panels each running to its own controller. Then I also have a portable folding panel I can lay out wherever and it runs to its own controller. All the controllers run to a common bus which then feeds my batteries.

You must have a pretty decent load if 600 watts is not keeping up. You probably want to shift to lithium when the time comes for new batteries.
