Moving the work to be done instead of the power

I enjoy new ideas as the whole RE usage and generation matures. Here is an interesting idea that I read this AM:

Yeah, there are probably some challenges in this but people are thinking outside the envelope.

Enjoy,

My RE system: Outback - Garage roof:
- 8 (2x4) Evergreen 180's into one FM80 (2007/2020 - replaced MX60)
- 6 (2×3) ALEO S79-300's into one FM80 (2017)
- 2 grid-tied GVFX3524's classic stacked for 120/240VAC (2007)
- 12 Surrette/Rolls 2V x 1766Ah (2007)
- Hub10.3, Mate3s, FNDC, RTS, OpticsRE. Tigo Energy ES maximizers on each PV module.

Westinghouse Solar - Barn roof: (2012)
- 30 (2x15) 235W panels with Enphase M215 microinverters, grid-tied

Outback Skybox - Barn roof: (2019)
- 14 Talesun 275W in series (DC array input to SB inverter/charger)
- 3 SimpliPhi 3.8 batteries, 48V, 225Ah total
- AC coupled input (manual switch during grid outage only) from 14 Talesun 275W,
Enphase M215 microinverters, normally direct grid tied

It seems to me a more immediate solution would be widespread adoption of electric vehicles, which would mostly be charged at night.

My 2 cents.

Yeah, that's a great point. Today's article of interest was about the grid of the future. Later in the article it addressed to use of electric vehicles as a storage source and a provider which we've probably all heard about. But it goes further in that one car might be able to use/buy power when it is cheaper (even negative price) and then sell it when at a higher price. I read more into this concept than just vehicles as in grid connected systems. This 'smart grid' would provide instantaneous pricing information so that the various producers/consumers (prosumers) or storage resources like the EV (store-sumer) could choose how to utilize resources and need based on the typical use of the EV or prosumer's and the participation.

I've always been fascinated with the grid and transmission. This article is part of a series and this is #3:

Bottom line for me is I would LOVE an EV that had AWD and sufficient ground clearance. But I don't have the off grid infrastructure to charge the EV. This is a cool look into the future for those who are grid connected. The other thought is this could be like the 'save money on your auto insurance' scheme promoted by the insurance companies with the plug-in module. But by the time you buy/rent the module and pay for the subscription you are at break even. Then you have volunteered you all the info they need to raise your rates: speed, acceleration, cornering, location and exact use and time.

It's a complex world these days. It's wonderful. In other ways not so much so.
Best, JRH

Yeah, I knew that might be a deal breaker for your remote offgrid homestead. I've got an EV so I know nighttime charging is part of the solution to the new grid's overabundance of distributed energy. Good article.

I couldn't agree more.
