Ok well i have discovered that all inverter use power even when they Jeep and inverter is off. Thanks to my now dead battery. So to live and learn. I have two options i'm gonna toss out there. the first is probably cleaner and safer (in terms of killing your battery) but is more complicated and will cost more. It involves running a relay with a switch (or to the ignition) between the inverter and the inline fuse. Here is a simple diagram (replace lights with inverter)

light_schema.gif

If you do this make sure the relay and switch you get is properly rated for your loads.

The route i am most likely going to take is running the inverter in parallel with the Jeep. I will wire in a kill switch between the inline fuse and the inverter to kill power to the inverter when it is not in use.

Expect pics and more info to come.

yea the inverter will stayed powered by the battery since no kill switch on it. i mad taht mistake with my sub amp and my battery drained over night and jump starting the jeep with a car was real fun

when you add a switch get the +12 from a item that will power off with the jeep and will kill the inverter with it. a fuse tap to the radio should work good for your switch +12 to tell teh realy top power the item

your going to need a strong relay for that line since most in stores are only 30/40 amps


did you just bypass the switch on the inverter?

What do you mean?

oh and there are relays that are strong enough on amazon for $15

The switch with the inverter still works

your adding relay and a switch

the relay has
- line with power from fuse
- line of ground
- line to accessory
- line from switch

the switch
- line to relay
- line from +12V item in jeep or batty
- ground if it has a light

when the switch goes to "on" its sends the 12V signal to the relay to connect the circuit and power on the inverter. when the switch is "off" no 12V to relay so inverter is off or dead

if you connect that +12V to a item that shuts down when the jeep is off (like radio) you dont have to worry about the switch you are adding being on and draining your battery. its like another fail safe

the relay will be more for protection like adding a fuse to a power line.
make sure the relay dose not have 16 gauge connection if using the harness they come with.

yeah as i said in an earlier post i'm probably not going to do that. I'm probably just going to install a kill switch some where, but thanks for the explanation.

killer setup man, but in also going along with justification to the fiance of the project, i'm putting in slightly more powerso i can run the mini fridge on extended trips for her redbull and vodka. im thinking cobra 2500w/5000peak with it's own battery in the trunk. battery would be in the spare tub, with the inverter screwed onto the back seat like a sub amp. i didnt know about the drainage thing until i read your thread tho, so i'll prob go to west marine and grab a battery switch for it like we put on our dump trailer at work. fairly easy install, plus there's a funky surplus store here that sells anything you could ever imagine electrical related for cheap. any opinions/ideas/suggestions?

so, if i get an inverter that has a switch on it, it then shouldn't be "running" when it's "off" right?

No it won't run if it has a switch and its off, also I hope you don't pan on running anything off a 2500/5000 watt inverter with the alternator running, you will kill it quick, that's 200A/420A alternator is rated for like 125A, see where that might be a problem? If you hook the battery up to alternator I would put a switch in so you can run without alt then switch it on to charge batterie(S) one battery would be kaput after a little while at 2500W.

What are going to run off that big of an inverter anyways? A small house?

I've got my 1200W unit under the rear passenger seat. It drains power, even when the switch on the unit is turned off. There is a small, dim, green status light that stays on all the time. My battery goes dead after 2-3 weeks of sitting, less if it's cold out.

Next time I'll have to work in a seperate kill switch like mentioned above.

got a killer deal on craigslist. 2 optima batteries, brand new, one red and one yellow.......$100!!! yellow for the jeep, and red, along with old maxx battery to alternate power inverter. i can now charge my tools, run my mini fridge while camping, and pretty much power anything else that may need to wheeze the juice

how do you plan on keeping the inverter battery charged?

This, If you charge it off the alternator, you must put a way to stop the current flow from the alternator to the inverter battery when you have alot of load on the inverter (1500 Watts +) or else you will fry it.
