I don't have a place to plug it in at the moment that's why I'm using the panels but my 12v battery doesn't last very long at all without having to be charged and that's only running my small fan at night and my 22" tv maybe 5hrs a day. I have my RVs 2nd battery that's supposed to run the inside but it's not working right now.
So I thought if I took my shore power cord and put it directly into my inverter hooked up to the battery and solar panels that it would work the same way it does plugging it into a regular outlet power source.
I used to do it just like this, it works fine...but it is critical that you disable the onboard converter when doing so. Otherwise the converter gets energized by the 120V AC from the inverter and it tries to do its job of providing 12V DC charging. This will cause it to try and charge the 12V DC batteries while also drawing power from the batteries via the inverter. An energy draining loop is created...
On my TT, the converter AC input was pigtailed into the AC breaker (GEN). I bought another AC breaker from the hardware store, popped it into an available slot in the AC board, and removed the converter power input from the GEN pigtail and wired it to the new breaker. Then I used that breaker as an on/off switch for the converter. You'll have to investigate how your converter is powered and find a way to disconnect it.
Also note that your whole camper 120V AC system will think shore power is available, so don't use things that are beyond your inverter/battery capacity or it will overload the inverter. Make sure a propane fridge is on gas only, water heater on gas, don't use the air conditioner or microwave or other high-draw AC items.
Alright thank you I'll give it a try, I won't be using the water I have to fix all the plumbing stuff the only think I need to work is the wall outlets for my small tv mini fridge sometimes my microwave(when needed) and I have a small ac unit I use for the summer and tiny space heater in the winter but I won't have everything plugged in at the same time anyways. I'm still remodeling the whole camper so I don't need much all at once I just wanted to know if it was okay or possible to plug the cord into that kind of power system instead of a house or campground kind of system. Until I can get the solar panel system hooked up properly.
I'm not completely clear on which of your batteries you are going to use to run the inverter, but in either case you would want the converter disabled so you are not trying to charge a battery with a battery. You will get the convenience of all the camper's AC outlets being live, just like if you were plugged into true shore power. But that doesn't mean it can operate just like when plugged into true shore power. A single (or even both 12V batteries working together in parallel) will not be able to operate much. Small TV no problem, mini fridge maybe for a short while, AC unit no chance, space heater no chance. The solar will not increase the capacity to operate things really at all, but it will provide a little charging when there are no other electric loads in use.
