Normally what you would want to do is upgrade your existing battery bank to at least 2 deep cycle batteries
(I have two 6 volt golf cart batteries wired in series to make one large 12 volt battery bank) this would be your battery bank for your entire trailer.
You could go with Lithium batteries but they are fairly expensive .
Then you would buy an inverter and install it where the romex loop comes over to your solar prep area. The inverter needs a transfer switch as well.
(Built in or separate)
When plugged into shore power your entire trailer runs off of the 120 volt shore power for electric outlets,Tv,etc
120 volts passes through the inverter via the transfer switch and the three solar outlets are powered as usual (120 volts)
Your lights ,water pump etc run off of the 12 volt converter when plugged in to shore power.
Your batteries are also charged by the converter.
When you disconnect the shore power cord, the lights,water pump etc will run off the batteries
The inverter will take the 12 volt incoming power and convert it to 120 volts ac.This will give you three outlets for tv, charging phones,Cpap machine.etc
(Probably stick to min 1000 to 1800 watt max inverter)
You will not be able to use any high amp draw items like microwaves,air conditioners or heaters,coffee makers. These would deplete the batterys pretty fast
You could then have a solar panel or panels to charge up the batteries.
Smaller suitcase panels of at least 200 watt would be a minimum.(they make smaller but would take forever to charge batteries)
You would also need a solar charge controller ( some suitcase systems include it)
Renogy makes some affordable nice systems
This is for a basic system like I have.
Some on this forum have really elaborate systems costing thousands of dollars
I’m sure you will get answers from those more knowledgeable on the subject
