Gunny: What is the purpose for the "Buss Bar" located under the drivers seat? Why not just run the wire directly from the relay to the 250 amp fuse without the "Buss Bar".

I should complete my "vehicle" inverter installation this weekend. I will post some pictures when it is done. I ended up mounting the 600 watt inverter to the back of the passenger seat base instead of under the seat. I did use your input to run a 3 wire cord from the inverter duplex plug to an easily accessible duplex plug on the inverter enclosure. Thanks for the idea.

Basically the bus bar is another tap in point for running other accessories off the aux. bat.
i.e. rear back-up spot lights.

Gunny,
Great DIY job with excellent "show and tell".

I have a 1100 watt Exceltech sine wave inverter that I am planning ( for about 3 years now) to mount under the hood of my 2500 '08 Cargo. The under the hood location is for better cooling and will be just below and in front of the Aux. battery mount. I will also fab a heat shield between the engine and inverter and splash protection. Exceltech put a 'conformal' coating on this inverter for additional moisture protection.

My novice thought is that there will be less power loss running the 120V AC wires from the under the hood inverter location back the the small appliances in the rear of the van, than if I were to run the heavy DC cables from the Aux. battery to an inverter mounted under the passenger set. Am I mistaken??? Is my theory wrong??? Your advice is greatly apprediated!

Thanks for your input. You can see what I did on the Orton DIY-vehicle inverter installation post.

Great Inverter location question.
I am looking forward to the Forum answer.

Barrelsaver, You're not mistaken and your theory is correct. I wanted mine under the seat. My manufacturer didn't recommend the unit mounted in the engine compartment due to heat and getting wet. The unit I sized was larger. The cables was sized at the maximum (4/0) minimum voltage loss or drop at maximum current draw. I am very happy with the choices I have made. My set up works perfectly for me.

And I love it!

Gunny,
Thanks for your quick response. It's a relief to know my approach of putting my inverter under the hood, with proper shielding, is workable. Your RivNut method is just what I plan to use. I will post a write-up with pictures when I make the installation.
Thanks again,
TK

Proper heat and water shielding is the key point. Remember, water can come up from below, above and through the front grill.

We have a 2014 ERA 70A and plan to put a Xantrek 1500w inverter on board, hard wired to the outlets. We have been boaters for years and I can say that 4 minutes of water heating for coffee or toast or a hot plate is not many amps. Our ERA has 2 AGM batteries that give us a 200ah house bank. We are only seeking to make coffee, not run AC. I cannot see where the few amps drawn in the morning have much effect on the house bank. As you all know, most of the Dometic seem to be a three way, as long as you recognize that the 12v is the food throw away mode. The frig draws very little and the alternator would provide more than enough to power the frig through the inverter. We are on a five week shakedown cruise to New England and the ERA has performed well, mpg for 3000 miles is a little over 20.6, high tank at 21.7 and low at 17.8. Well worth the two years we spent looking.
