Charging woes...

[Piotrsko]

And how do you split the 220? They are 110 v units that might stack if their proprietary coupling cable includes a phase synch, which the advertising hints at. However at 2 grand each, I'd rather get a big generator and run it off bbq propane tanks.

The generator replaces solar or hydro, the battery replaces the grid.

The cable is as you describe, but I see prices around $1200.

As redpoint5 said their are mitigation strategies that don't involve public utilities rapidly adding peak capacity. Time of use pricing is one and I fully expect most utilities will switch to mandatory time-of-us pricing in the next 5 to 10 years. It is already starting in the USA and the UK National Grid plan I linked plans on it.

Looking at my utility the time of use pricing is:
6am - 3pm $0.07 per kWh
3pm - 8pm $0.12
8pm - 10pm $0.07
10pm - 6am $0.04


So, I leave for work at 7am and my smart thermostat regulates my thermostat to cut back power. I work and then arrive home at 5 pm. I plug my car in to my home charger but instead of charging the car my home switches over to draw power from my car instead of the grid. Then at 10 pm after I've gone to bed the charger switches back to grid power and charges the car and powers the house. Maybe I've loaded the dishwasher that also gets turned on to run at night. Maybe my hot water heater is also times to lets the temperature fall during the night but turns the tank back on at 5am so I have hot water for my shower 6am

More like I was trying to joke that Somalia is so backwards they have their own electrical standard.

120v and 240v root mean square is US residential standard. 110 and 220 was an older standard.

Single phase is also US residential standard.



Confusing because the voltage at 1 wire goes positive as the voltage at the other goes negative with respect to ground.

Isn't the correct term called "split phase."

It's also an inverted polarity to neutral, not just ground, which is connected to ground but for some reason isn't called ground.

The funny thing is electricity in the US has neutral, but no drive or reverse.

Even though it's much the same standard elsewhere, already accounting for some voltage oscillation, in my country it's still common to refer to the old standard even though most electric appliances in regions where the grid is now refered officially as 127-volt are labelled accordingly.
