Near-grid generation & usage (NGG? NGGU?)

Near-grid generation & usage is something I know many people do, but I rarely see it discussed as such.

Do you own a solar calculator. ? Are you using it in a grid-connected building? Do you use a battery in your notebook? Do you ever power it with solar panels or from your car? Then you're using NGG. You're still on-grid but at least some part of the off-grid appliance you're using is being powered from another source.

Do you stop there? Okay, but you don"t have to.

Isolate some part of your household load, out of your main panel, and onto its own battery / solar set. I know this is a basic concept (many here may be saying, 'well, DUH!' ) but it's a stepping stone for people considering solar for the first time - remind them that they don't have to pull their entire house off grid and they may not necessarily have to buy a permit for a house/grid interconnect system.

Consider powering a garage deep freezer with a small solar setup and an isolated circuit. It may suit your needs and allow you to experiment with solar power in a much more beginner-friendly way. Also, you can find a ratio of ice-to-food storage such that you generate enough ice in the day to maintain frozen temps at night without electricity usage at night, so you can, theoretically, do it without investment in electric batteries.
 
Love this topic!

 
Victron produce a free 'Energy Unlimited' eBook that discusses local/micro power generation and how it can be used to offset grid costs. It's an interesting read.
 
Thanks for the book link! Lots to think about & a method for calculating a spaghetti dinner's energy use.
