Re: AC power converter

Re: AC power converter

You'll need to add up the watt draw of each appliance to get an accurate idea of your power needs. There should be a tag on each listing amp draw.

To get watts, multiply amps times volts. Say your refrig draws 2 amps at 120v, so 2 (amps) x 120 (volts) = 240 (watts). Do this for all your appliances and you'll have your total (peak) watt draw.

Of course, you won't be running all your stuff all the time (and the refrig only draws the full 2amps for a second or two at startup) so your average draw will usually be much smaller than the peak draw. Converting AC to DC costs you about 15% so at a hypothetical 1000watt draw you'll be pulling 1150 watts from your battery bank so you'll need to figure out how many watts you consume in an average day and size the battery bank accordingly.

I'm guessing you're going to be tailgating with no shore power available?

"I'm guessing you're going to be tailgating with no shore power available?"

that is correct, i go to alot of music festivals that do not provide shore power. I would like to be able to run my fridge all weekend in cases like that.

Thanks for the formula i will have to do some math homework haha

Re: AC power converter

I have a 6000 watt power inverter and I run a 42" tv, mini fridge, roof mount Dometic AC and 5000 watts of stereo power off of 3 Type 8D batteries with 2 gauge wire and a 250 amp alternator. This is while the bus is turned on. I'm not too worried about an isolator or anything although some people are. Especially if you are out in the middle of nowhere.

The 3 batteries are strong enough to run the AC and TV and stereo for a while, but I never did the math or tested it to see for how long. Instead of wasting diesel where there is no shore power, I just use a gas generator.
