Power Inverter Start With Car Help

Hey guys,
I'm installing a 1200 Watt inverter into my truck. I ran a red an a black 4 gauge wire to my battery for this. The problem is that it never shuts off.

The inverter came with a remote. This remote connects to the inverter through a phone cable.

I can turn the inverter on by touching the yellow and green wires. And to turn it off I can touch the yellow and green wires.

Is it possible to wire this thing up so that the inverter turns on and off with the car?

I would be open to some kind of solenoid on the red cable too if it's not too expensive.

 

Without a wiring diagram we can only guess.

I assume the remote is just a spst switch. If it is then you can run a relay that is activated by a circuit that comes on with either accessory or ignition and then the relay can close the remote circuit.

My honest opinion is if you couldn’t figure this out on your own then you need to involve someone who has better electrical skills than yourself.

 

The way you described that you can turn it on and off by touching the wires sounds like a momentary switch will work connected to those wires. if you have to leave those wires connected for the inverter to stay on, then you will need a single pole single throw switch.
Or, use a relay that you will wire up so that it turns on with the truck to turn the inverter on.

 

I would agree by the way it is described but one of the inverters I have has a similar remote to what is described and it is definitely a SPST switch. Same rj11 cable. I wonder if the way he is touching two wires is not the intended way of wiring and it is a fluke that it is coming on and off this way.

I never used my remote and would have to dig pretty hard to see if I could find it to confirm the operation.

 

It sounds like you need a logic circuit that will supply power to a 1 shot relay when the ignition is on and the inverter off and also when the ignition is off and the inverter is on. Should be able to do it using the NO and NC contacts of a 12V relay and a 110V relay. Since this will be intermingling 110v and 12v, you're on your own. We can't risk giving you advice that could fry your truck if you make a mistake.

And if you want to get really creative, you could use an on delay relay in the 12v ignition feed so that the inverter turns on 15 seconds after the truck starts.

 

I agree, I'm not an electrician, and I don't want to fry my truck. I've just found that sometimes these things are really easy and sometimes they're not. A question is always worth asking.

 

It may be a fluke, I'm not at my truck right now, I'll check when I get home

I found this video, where it seems to act more like a STSP switch, if that's the case makes it all more simple. I was just confused because it seemed to be acting like a momentary switch.
I may be wrong, wouldn't be the first time

The way you described it in your 1st post is drastically different than the way it shows in the video. You described it as a momentary switch that turns on the inverter when momentarily connected and turns it off when momentarily connected.

The video shows it turned on when 2 wires are connected together and turned off when disconnected.

Drastically different in the circuitry needed to accomplish what you want to do.

 

Easy.... Really.
Using a Bosch relay, connect the green and yellow wires to terminals 30 and 87. Insulate terminal 87a if it is there.
Terminals 85& 86 are the coil. I don't remember which is positive, hopefully someone will chime in. Never the less, get an add a fuse and and pick a fuse that switched on with the key, the other terminal gets grounded.
Now, if you want to do a time delay so that the truck starts and settles, you can do the following:
Get a 100 uf ( microfarad) 25 volts dc electrolytic capacitor. These have positive and negative leads with the negative identified. Now, multiply every second of delay by 10,000 and that will give the value of the resistor needed to create the delay. I don't know what the coil draws for current, but i think a 1 watt resistor should do. Conne the negative side of the capacitor to the grounded wire to the terminal. Take the other end of the capacitor and one end of the resistor and connect those to the other terminal. The other end of the resistor gets connected to that add a fuse I mentioned earlier.
Get the capacitor in the same style as the resistor. Use insulated crimps for connection to the relay and the resistor/ wire connection.
You said you ran a 4awg wire from the battery to the inverter, no mention of a fuse. THAT right there is how you fry the truck.
Hope this helps.
