Hey there everyone. Long time follower first time poster. So long story short me and the girlfriend just got a '77 31' Sovereign
with the rear bath. Currently interior is gutted and moving on to re-insulating and putting in solar.
Current state of electrical is that everything works fine. Owners manual describes the system as when running on batteries only the DC lights and DC (automobile cigarette lighter style) sockets work for appliances. The manual says that the AC sockets only work when hooked into shore power. There was a converter in the trailer and I guess this was simply to convert shore power to 12V
DC to run the lights when plugged in.
Now here's the funny part. My knowledge on electrical systems is very crude. Now, the dilemma:
I want to install solar. But I'm trying to wrap my head around the switching between AC/DC for running lights, outlets, etc...
I understand that if I wire my new batteries into the system the existing 12V
DC lights will operate just fine because that is what the 12V
batteries will be putting out. Now, I'm also going to wire in an inverter to take that 12V DC power and be able to run the AC outlets and appliances, etc... when boon docking using solar.
So, what will happen when I hook back into shore power? Can I run the shore power to my batteries and they will charge when plugged into shore? If this route, would that take place through what I'm hearing is called an "automatic transfer switch"? This would switch to charging my batteries from solar panels to being charged by the shore power when plugged in?
Long question short given that my interior lights are DC and my outlets AC what is the best way for me to make my system work so that I can just use my batteries when boon docking and still be able to run everything when plugged into shore power?
I know the knowledge is out there. Can't wait to see you everyone has to say!
