Some comments about this we saw on the web:
* /u/scarabin on /r/BurningMan that’d do it; i don’t know why you’d need two inverters though.also you want a deep cycle battery rather than a regular car one as car batteries are designed for short bursts of high energy rather than a sustained drain. deep cycle batteries are used for running the electricity on boats and RVs. make sure to get one that’s “100ah” or higher. that’s essentially the amount of power available in the battery and the more you have the longer you can power your stuff. you can get two and connect them in parallel (google image this for a diagram) to increase your available energy.
you’ll also want to get a battery charge reader so you can monitor how much charge the battery has. a full charged battery is 12.6v, and you should turn everything off and recharge if you dip down to 12v as that’s around 50% charge and anything less than that will actually kill your battery and it won’t charge again.
definitely don’t do the gennie, we have enough air and noise pollution out there…
