Dependent on how far you are installing the INVERTER from the battery..is dependent on the wire size.. shorter run then smaller wire... longer run.. bigger fatter wire.. there is an electrical wiring code that will help you). PLEASE NOTE.. the wire size is proportionate to the size of the inverter too.. I have a pure sine inverter 1000 watt inverter and run 6 feet of "O" size welding cable... reason for wire size.. I can upgrade to a 1500 watt or 2000 watt inverter in future without worry of heating up the wire... heated wire equals bad things!!!! fire.etc. if you are running a short run from the battery.. 3-4 feet the #4 will be fine!depending on the size of the inverter.
From the AC side of the plug in on the inverter goes the 120 volt ( 14/2) line. please note Blenders after 5 pm ( marguerta time ) work GREAT on this setup !
Here is a shot of my TT in Arizona last winter. I am not that big, say 15 ft. The 2 batts are about 4ft from the CONVERTER. My TT does not have an INVERTER installed. I do have a 400w that I plug into a 12v dc power port I installed. The wires coming in from the batts are #4. A bit big I think. The stock light bulbs were incandescent: 8 bulbs. Now all bulbs are LEDs.
Here is a shot of the back of the converter. Hopefully you can see the difference in wire sizes. I really would like to downsize the main batt wires so the wires will fit in the solar controller. At no time will any wire be more than, say 5 ft from the batts.
A view of the electrical under the dinette seat.
Currently I have 2 size 24 12v batts. When these die I would like to in stall 2 size 27s or equal 6v if not to heavy. Though probably will be. I like TV. So I would like to keep up my batts w/o running my Honda 2k gens. This is my home on the road, so I carry a lot of stuff.
I am just trying to wire up my solar controller w/o looking like a drunk did it.
Here is were I would like to install the solar controller.
Thank you everyone for your input.
