After opinions on my 12v design? Anyone interested?

Unread post by stormers15 » August 11th, 2016, 7:55 pm

Hi

I am desperately keen to get a 12V setup in the back of my Landcruier 200 series. I have build my own drawers and now want to use the "wing" spaces to set up a 12v "board" on one side and a inverter and 240V outlet on the other side. I have done lots of reading on 12v systems and have "designed" my own one. Will some one on this forum be willing to give me his/her opinion on what I have done, please?

Hi Stormers, I'm sure you'll get plenty of opinions & maybe even some helpful comments if you give us some reasonable detail about what you've done & what you're wanting from it?? ;)

Ok, here we go. If you have a quiet chuckle about my drawings, you owe me a beer. I am not a designer at all, my kids are. I am only a vet. Cheers!

I think previous picture poor quality. Can you look at this one, please?

Id say 26mm2 is bit overkill for one, it will be difficult to get lugs suitable to join 26mm2 to your fuse panel and you will want a stranded cable as well no house type wires. prob really only need 6b&s or 4b&s. but otherwise it should be ok as is.

Thank you very much! The only reason I chose the 26 sq mm was for voltage drop. Really appreciate you help, Muckinhell!

Couple of things. Fuses are to protect the cable so fuse according to the cable's rated capacity or the component in your circuit with the lowest capacity, e.g. 50 amp Anderson plug. Any appliances are protected by the fuses in the fuse block or its own inbuilt fuse.
The inverter's manual will suggest an appropriate size for the fuse in its supply cable, use the recommended size.
The Ctek 250 will accept an unregulated solar input. Would be better to insert a couple of Anderson plugs on your solar panels to bypass the built in regulator and feed direct to the Ctek. This way any voltage loss will be less after the regulator. A bypass of the panel's built in regulator allows you to use the panels elsewhere.
And yeah, 6B&S or 16mm2 solar cable would be sufficient for your setup.

Cheers mate
2 questions: So what you mean is that I set up my solar panel so I have an Anderson plug between the built in regulator and the panel itself. I can then either connect the solar panels with the in line regulator if needed or directly with another Anderson to the Ctek? Clever idea! Def will do that if that is what you suggest.
Also, do you trust the "resettable" fuses or do you guys use the standard ANL fuses and inline holders?

Yes. You will need 4 Anderson plugs to bypass the regulator if the cable from the regulator on the back of the panels is hard wired in. Cut the cable going into the regulator and add 2 APs. Cut the cable coming out of the regulator and add the other 2 APs. Now you cab bypass the regulator on the panels and go direct with the panel's 17 or 18 volts direct to the Ctek. Less voltage drop that way. Can also use thinner cable.
For what you are doing, resettable circuit breakers are OK. Or use fuses. Either or.

Also, a good place to buy all your stuff is autoelecau on ebay. They have a Victorian store if you live nearby but post for free. Bought heaps off them and can recommend. Nothing more than a happy customer.

Thanks! I did discover autoelec in my internet searches and have ordered some of my stuff from there.
