Default Electrical Question, Power Inverter

I have an 09 dodge Ram. I would like to put a power inverter on my truck so I can run my basement sump pump in the even of a long power outage from a storm. From what I have been able to figure out is that my sump pump draws 5 AC amps while running. 5ac amps X 120V = 600 watts. 600 watts / 12v = 50 amps. Someone correct me if that is wrong but Im assuming at a minium I will need a 600 watt power inverter and my alternator on my truck with need to have atleast 50 amps to spear for my sump pump.

My Questions:

How many Amps does the stock alternator put out at idle?

Is there a way to increase the idle speed for higher output from the alternator?

How many amps does the truck require to run its necessary systems?

Are there options for higher output alternators?

Thanks for any help.

Nick

Well my calculations come to just over 55 Amps at 12v DC. There is a loss in the inversion. There can also be a loss in the line and the pump probably needs to have extra for start up. But why would you want to do it that way?

You would be better to buy a small generator. It's a much more efficient way (petrol wise) to go. I paid $300 for a 4000 watt generator. It's capable of running the sump, the heat/hot water, the fridge and a couple of lights easily.

The Chef nailed it on the head. Why would you want to subject your truck to that kind of electrical abuse? Get a generator and save your truck. If the generator breaks, you're out $300 bucks. If your truck breaks, add at least another zero.

Default Sump

I have a battery powered backup on mine. Check Lowes and Home Depot. It's designed to work in a power outage even if you're not home and it's less than a small generator.

gas for running your Ram would hurt you
the strain on your electrical system will hurt it

a portable generator uses quite a bit of regular gas too, depending on size
propane powered generators are an option

There are backup sump pumps available that use your household water system to run. No worrying about power or batteries. You set it in the sump beside your current electric one and set the float a little higher than the normal pump and if the primary fails, the water propelled one kicks in. No worries about power or battery as long as there is constant water pressure available.
