Thread: Setting up a swtich to turn off inverter when computer turns off

will the computer still run?

You want an ITPS

I was using an ITPS with my inverter. When turning off the ignition switch, the ITPS would tell my computer to shutdown/hibernate. After doing so I would have it cut the power to my relay that was inline of my inverter.

Worked pretty good. I've since moved onto the Opus 150 mostly to save space but an ITPS is what you are looking for.

Thanks for the quick response! One of the problems with an ITPS is that I want to run the computer sometimes when the car is off or after I shut the car off. From the way you're explaining it, an ITPS wouldn't allow me to do this. Please correct me if I'm wrong.

Look at this post....
Inverter not booting pc after second try

Dunno if that's what you're looking for, but I can help you with this if it is.
A brief explanation of how it works is:
turn key on, triggers relay, starts inverter, boots pc, psu relay trigger starts
turn key off, head unit relay trigger stops, psu relay still goes(inverter, pc still on)
after 2 minutes XP Fake UPS starts hibernation, pc goes into hibernation, pc shuts down, psu relay trigger stops, relay switches off, inverter switches off.

Everything's auto.

Also you could set that 2 minutes to whatever amount of time you'd like so if you ever wanted to use the pc with the car off you could.

Woh - it's an inventive solution! I will look into it, but was hoping there would be a solution a bit simpler....

Thanks!

It really is pretty simple and I'd be glad to help you(I help in laymans terms too :0) ). If you want the help just pm me.

In my last build I kept the headunit for audio processing/amp so I used the Antenna remote line to switch a relay in much the same way.

I would shut down the PC, then switch off the headunit, and bingo, inverter isolated.

I'm going with an Opus and epia and direct to a car amp this time, so won't need to do that.

just curious as to why you dont want to leave your inverter on while the car is off?
