TT inverter and solar newb question TIA

i have been reading as much as i can to try and learn as much as possible before diving in. I'm new to TTs and new to solar so please keep that in mind.

i have a 2017 26bhsw.

current plans
1. install 2 6v deep cycle battieries
2. then install solar
3. have a 2000w inverter generator as backup.

so for the solar. i think i've sized it at least for the time being to a good starting place. like many of you i will go with the renogy 200w kit.

so for my question.
solar install seems pretty straight forward. panels to charge controller (add inline fuses) then charge controller to battery. My question revolves around inverters. if i charge my batteries, do all my outlets in the TT work? why do some people install another inverter? doesn't the TT already come with one? or is that where I'm wrong. I guess i could easily answer that by disconnecting from shore power and see if all my outlets still work?

any clarification around this would greatly be appreciated.

120V outlets will not work without shore power on the factory set-up. Your trailer does not come with an inverter. It comes with a converter that converts AC power to DC and charges your batteries. If you want any AC devices to work when running on battery you need to install an inverter that changes DC to AC.

Your TT has two systems. 120 volt and 12 volt.
The lights, water pump, radio operate on 12 volt.
The refrigerator and furnace operate on propane AND 12 volt (or the frig can also run on 120 volt).

When you are plugged into shore power (120 volt), your converter keeps your battery charged and also runs your 12 volt systems AT 12 volts. It converts 120 to 12 volt.

Your electrical outlets, air conditioner and microwave all run ONLY on 120 volts.
Your water heater can run either on propane or 120 volts.

An INVERTER will convert 12 volt DC to 120 volt AC and it can then run things like your TV, coffee pot, DVD player, etc. However, it cannot run your Air Conditioner, and it can only run your microwave if you have a very large battery bank and a very high wattage inverter.

This is a typical 30AMP simplified electrical scheme...

Gives you a pretty good idea how things are arranged so you can operate your 30A Trailer from shore power connection or from the battery...
