4 new batteries and an inverter problems?

Also, I am wondering how you got 20 amps, as a previous poster said the inverter can use about 16 amps. That would mean the alarms would have gone off almost instantly and the inverter would have shut down, correct? I also mentioned that when I tried my 1000W, the computer ran fine until I played a game. And even then, the power draw wasn't enough to burn it out. The mini inverter just kept crashing and booting as fast as if someone was clicking the switch on and off. Since the 1000W didn't just blow up, wouldn't that mean the acceptable range of power draw would be somewhere between 1000W-2000W, especially since my laptop is the only thing I ever have plugged into my inverter?

 

Okay, say for the sake of argument that it isn't the inverter, and perhaps it's my PS. Would buying a different one be a solution? And if so, do I want one that's smaller and has a higher output? There is a compatible charger with a max output of 19.5V, 16.92A, and 330W. Again, I don't know what I would be aiming for. I just know my company will not allow me to use any other type of inverter, and I doubt they have any with higher wattage they are willing to install.

 

I would not have to pay for anything, really. The truck is owned by the company, so anything that breaks down is paid for by them. I did have to pay for the original inverter, however, the purchase came with the company lifetime guarantee that if something happens to it, they will replace it with no charge to me. I also get to take the one I'm using with me if/when I leave.

 

There have been a few times when I was put up in a motel by the company while serious repairs had to be done on the truck that required taking it to the dealership. During those times, as well as very hot days in the summer when I was forced to keep the truck idling so that the AC would run (I'll be ###### if I'm going to sweat in 80+ degrees for anyone) the the PS worked without any problems for both the motel outlets and the inverter

 

Little note: I had to move the truck, so right before I turned it on, I turned on the inverter. Both the truck and inverter have been off since 2300 central time last night. As soon as I flipped the inverters switch it started to beep. There was nothing plugged into it when I did. I also checked the voltmeter when I turned on the engine. It started at 12.7V and gradually rose to 14.1V in about 15 seconds. Usually its at 14.2 V, but I don't believe that's a huge difference, right?
