I want to power an rv with a 24v solar system, is there a way I can hook it up to the shore power plug? Or will I need to wire up each thing in the rv?
Can you explain what you mean, I think the answer is a hard no, but I'm not positive I understand what you are saying correctly.
For reference, Shorepower is 120V AC (or 240V AC maybe), So you can't hook up a '24V' DC solar system to it.
You need to connect your solar panels to a solar charge controller which is in turn connected to the battery.

Works in theory! Practice? That's something else
I believe Will has examples in his blueprints (link above in the blue bar).

Im going to go off grind but im starting off with an RV then building up a cabin. Im going to have only solar as my power system so I wanted to know if there is an EZ way to power the RV. without having to wire up each thing in the RV? The vid I saw was Will had a fuse box from his 24v system to power each thing. Is there a way just to send all the power to the RV plug on the outside and let it do the rest?
I know ill need an inverter to change the DC to AC but after that is there a simple way to use it?

Say I make a solar shed(with Controller, bat, inverter in it) and have 1 plug come from it to the RV.

Ok this is what im trying to do I want to build a solar shed and have it go to a 50amp shore power plug. That way I can move the RV at any time and not have to worry about the solar

Sounds reasonable, what problems are you encountering you need help with? Seems like:
- Do an energy audit
- build a shed that can handle the number of panels, leave some extra space for growth
- Install panels, SCC, batteries, inverter, load center to meet needs
- Mount a 50 Amp Temporary RV Power Outlet on the side of your solar shed (or a pole near the RV parking spot)
- Determine the total wire-run distance to RV
- Determine the correct wire gauge for the number of amps the inverter can supply (a split phase 50 Amp connector is 12,000 watts max)
- Get a 3 conductor cable with ground of the appropriate gauge/length
- Get and install conduit to protect the wire and run the wire through it (mount or bury as appropriate)
- Get a double ganged circuit breaker that will fit in the load center in you solar shed to power the RV and is sized appropriately (60 amp max)
- Disconnect the panel from the inverter, verify no voltage, then wire it into the load center.

Answer: yes...
Explanation... the RV has either a 3600W 30Amp 120V cord, or a 12000 50A 240V split phase cord.
the inverter you choose needs to have matching specs.
many RV electrical systems have generator transfer switches built in, and charging panels to accommodate a house bank of batteries.
you COULD have an external solar station that matches the RV cord of your RV and connect it there... or you can tie into the generator panel... or directly power the house bank with your solar setup...
options, options, options...

She just needs a 240V split-phase inverter that meets her energy needs. Just because a 50 Amp plug can carry 12000W doesn't mean she'll actually use that many.
Yes, I meant she needs to match either a 120V inverter or a 240V inverter depending on which cord type she has...
And the inverter needs to be large enough to carry the loads on it.

Actually... I need to correct myself... if you don't have any 240V appliances you want to run in the RV then you don't really need a 240V split phase inverter.
L1 and L2 in the 50 Amp Temporary RV Power Outlet can just be hooked up to the 120V hot out of an 120V inverter. See the discussion starting at https://diysolarforum.com/threads/total-newbie-looking-for-guidance.8903/post-96321

Put in an automatic transfer switch and run all AC power source to that (including output from your inverter). Power then flows from the transfer switch to your control panel/fuse box/breaker box ....whatever you have already.
Exactly how I'm running my 2 50A RVs from a single 4kW 120V unit. I actually have both lines joined at the inverter, so I have the benefit of using the second 6awg conductor. The 50A to 2X 30A pigtail splitter that connects each RV is in effect getting its 120V L over its own conductor.
