Cargo trailer conversion to EC

[Gotya01]

I am new to solar, I’m doing a cargo trailer conversion. I received some equipment from a friend, it is in good condition from what I’ve been told .
I have .
2 -350 watt solar panels
2 -6v golf cart battery’s
1 - power max 300 inverter
1- victron solar charge controller

The trailer has a 30amp shore power plug , and 6-15 amp breaker box . The goal with this trailer is to be able to go camping and do some off grid camping for 3-5 days at a time. I am trying to figure out how to charge the batteries when hooked up to shore power . I am looking for some advice and maybe direction on missing items that I should consider adding. I have included pictures of all the items I currently have for this project. I apologize for any incorrect terminology in advance.

Thank you

You are going to want something like this that can plug into the shore power system.

I'm new to solar, and am installing it on my cargo trailer camper. I also have a 30 amp RV input on my trailer, but want to power all the 12v stuff with solar when dispersed camping, and not using my generator. I have a "Battery Tender" lithium charger that I use to keep the battery charged and maintained when not in use, but it is a trickle charger so I will be upgrading it to something that charges a little faster. I use the Battery Tender when either plugged into shore power, or when on my generator. I do not plan on using the charger when on solar. I have a LiFePO4 100 ah battery and want to provide 12 volts for a 12 volt refrigerator, 2 RV lights, a 12 volt tv, Maxx vent fan and for charging my cell phone. I also have a laptop and tv antenna signal booster that will be plugged into the inverter. Not all of these things will be running at the same time. I am planning on starting out with 200 watt solar panels, and upgrading the charger to something that charges a little faster. Does this sound like a reasonable setup?
