150 inverter wired to aux battery?

Howdy peeps.

Just wondering if anyone has attempted to wire the factory 220v inverter to a constant power source i.e. an aux battery as opposed to having it run through the factory switched ignition feed.

On a recent camping trip at an unpowered site we were using the inverter to charge kids ipads etc and the ignition must be in the ON position to allow the inverter to run. Problem is the ignition will switch itself off after a set period if the engine is not started.

My thoughts were to disconnect the current 12v feed to the inverter and replace that feed with feed from my aux deep cycle. Obviously I intend to fuse and switch the feed so the inverter is not running 24/7.

Any electrical guru's with any advice/pros/cons would be appreciated.

Cheers

Chriso.

Problem is if you connect permanently to the battery it will be drawing
some power all the time.

I thought there was a way you can keep the ignition turned on, maybe someone
else can provide?

I think if you wire it permanently and add a kill switch to it then it won't be drawing power all the time. You can buy something like this http://www.ebay.com.au/itm/Rocker-sw...3150428&_uhb=1

Or a cheaper alternative is just the traditional missile switch hidden somewhere for it.

Yeah my thoughts were to switch the 12v feed probably somewhere in the cab with an illuminated switch.
Ive got some spare blanks available and pretty sure Ive still got a spare ARB Sidewinder switch with the LED.

Leigh - problem is with leaving the ignition ON is everything else wants to stay on aswell potentially flattening my main battery. Thats 'IF' i could work out how to get it to stay on for a reasonable time.

First thing I did after installing a rear power panel was run a wire over to the inverter and install a switch above the outlet. You need to remove the side panel, cut the 12V wire to the inverter and secure it and connect the wire from the aux battery via a switch. I used one from Jaycar with an LED to show when its on. You need to be carefull where you put the switch as the is not much room directly behind the 240V outlet panel, I had to bend the terminals on the switch so they weren't close to the metal panel behind it.
And here's a pic of my rear power panel, 2 Andersons, 2 Hellas, 1 cig, Narva twin USB and a volt/amp meter, and dunny roll

Bretthar,

Thanks for that mate thats exactly what I was on about. Really like your setup on the left hand side too. I find the TP sits neatly in the rear passenger cup holders

Cheers,

Chriso
