I'm wiring this straight to my battery. It will be mounted under my seat and I plan to run the two wires (pos/neg) through the rubber grommet under my dash over the battery.

And I understand that this inverter has a built in fuse, meaning I don't have to wire in a in-line fuse. Am I correct in this assumption?

Am I missing anything? Also, what are my options for the battery terminals with regard to attaching numerous wires up to them? Is there some type of device that will attach?

I believe the DI has a power block on the fender well that you can tie into.

As a recommendation I would also ground the unit to the body under the seat....you may also want to make sure that it get plent of cool air.

Never assume that the fuse that may be built in to the unit will do the job. If you are planning to hard mount the unit (not just leave in free floating), then you may have a hard time changing the fuse.

I would not put an inverter down so low, unless you are sure you will never go through water. I am about to mount mine on the ceiling, along with a few cigarette lighter outlets for convenience. You want a large fuse right next to the battery. For the cabling I bought a 4-guage (thick) jumper cable and cut off the clamps.

It will not be a permanent mount under the seat. Probably velrco to keep in in place while driving.

Dean, where on the ceiling are you going to mount it? Rear? How?

I don't anticipate driving in water, but it is a good point. I thought about tucking it somewhere up in the dash and just running (might have to build) some very short extention cords to dangle down for access.

Joey, ground the unit twice? or just under the seat?


Best place to buy this stuff? Radioshack?

Kristopher,

I have the SD D2 without sunroofs, so I'm going to mount a piece of ply wood in that area, and then attach the inverter (1000W) and some cigy lighters on the wood.

BJ's wholesale store sells inverters at 700W, 1000W and 2500W, it would be nice to have the 2500 but ut needs such huge cables to the battery its kinda rediculous. For the 1000W as I said I'm running 4 guage wire and a 150A fuse.

I always ground any major power unit twice....it is just they way I am. Keeps shorts to a minimal and you also don't have as much issue with RF noise from the engine that way.

on the ceiling what about the wires (plug ins) hanging? I think they would be in the way.

IMHO if I were to mount an inverter in my Disco, it would depend completly on where I would need the power, but I would think either the back of the center console (for easy access) or in the back cargo area on one side or the other. But this is just MHO.

Of course you always get creative in mounting anything, and everyone has an opinion.

You should fuse it at the battery also. If you get a short in the wire going to the unit, a fuse in the unit will not do any good. You need a fuse to kill power at the battery if the wire were to get shorted some how.

Kristopher

Vector makes a marine inverter that is supposed to be water proof, although from its pic it looks like a regular inverter. Might be a good call.

How many watts of power are you wanting?

I have a Coleman 400w inverter mounted on the drivers side wheel well of the cargo area. Ran power straight to the battery, and tested to find a good ground. Ending up being the frame when the jump seat mounts.
