Power Audit

Our intention is to Dry Camp as much as possible and it's important to me to figure out my usage so I can accordingly determine by battery and re-charge needs.

This is based on my camping style and my needs. If wish to have anything added please ask. I also ask that you look at these numbers for they are assumed or from research so far. I will have 'real' numbers once we start up next spring.

Oh ya, I have built a spreadsheet on this which I'll be happy to share once the numbers are close enough to work well. All my numbers are DC amps

Here I go:

First my needs and numbers:

Water Pump 5.5amps 1hr a day 5.5amps

Frig 2amps Run on propane )have heard as low as .5amps)

Water Heater .5amps 2hrs a day 1amp Numbers run .4-.67ah

Heater 6.7amps 1hrs a day 6.7amps Propane, think high, but fan use..

Power Slide 8amps minutes .8amp

Lighting 4amps 2hrs a day 8amps Set high purposely

Fan 1.5amps 2hrs a day 3amps Also set high for an average

Coffee Maker 13amps 7min .8amps I'm lazy and like my coffee maker

Laptop/cell 2.5amps once a day 2.5amps Probably charged from the truck anyway

Hair Drier 83amps 7min 2.6amps Every other day

Phantom Power 10% of above Unknowns

This puts me at <36amps a day. That's workable and here's why.

Battery 2-6v 210ah batteries drawn to 50% Giving 105ah use.

Solar my 130w panel giving on average 40amps daily (sun days)

Recovery by Solar 114% of daily use.

I have just <3 days of autonomy potential before I have to get serious about re-charging. 

That works!

Now, what do I have wrong or forgot?
