Why are you looking for a personal power grid? *

I want backup power during outages. I want off-grid power to power my cabin, toolshed, remote jobsite, etc. I want mobile power for my RV, mobile business, contractor's van, etc.

Do you know how much power you'll need to power your appliances each day?
