Give ne back my hat!

Is it possible to put your entire home on a UPS?

When I used to manage my company's datacenter, we had the entire datacenter connected to an online UPS.

The UPS had a bank of batteries and was fed street power.  The servers ran off of the batteries.

Our servers were protected from the dirty street power.  Of course, if street power dropped the servers still ran off of battery power.

Wondering if I could insert a UPS between the power company's meter and also the breaker box.

Oh, and if the batteries on the UPS were full, say, because they were being charged by solar panels, could the UPS push excess power back to the utility for sweet sweet net metering goodness.

This would check almost all of the boxes

1. be able to lower your energy bill with solar panels through grid-tie
2. get a credit back with net metering if you have an energy surplus
3. run off of the batteries if you lose utility power
4. bonus! provide clean power to all of your appliances. e.g. protection from brownouts

Shouldn't this work?

Yeah of course this is possible and it works.

Just install a battery bank for solar, and recharge off the mains.

Bank and install costs will run from $10k to $50k depending on your needs.

The batteries don't last forever, so plan on a full swap around every 5-7 years or so.

Don't you need some kind of controller somewhere that decides that the batteries are full, let's start sending power back to the utility?

That's not a UPS dipshit.

Of course not. The label clearly says battery for cynical market differentiation purposes.

Only an ultraviolet level geek demands perfectly shaped waveforms and voltage control down to 2% on his house electric. I'm not saying it isn't cool, but Powerwall is probably the most accessible version of this.

Get a bicycle, hook it up to generator, pedal all day, ??????, profit

Energy companies are not fond of such an arrangement, because they will get energy offered when they themselves will have a surplus, and must deliver when everybody needs it.

In NL and Germany these arrangements have been subsidized by the government, but now those regulations are coming to an end.

The battery stuff is meant so you don't have to sell when nobody wants it.

This problem with solar/wind energy not only exists for individuals, but for complete energy companies and whole nations.

Is that feasible? What could you run with the battery storage from one hour's pedalling? Boil a kettle? Heat a day's worth of hot water?

You can generate a disappointingly small amount of energy with your own body.

You could charge up the battery for your e-bike.

It strikes me as strange that people put together almost all of the same components used in a commercial datacenter when building solar power setups but fall very short, feature-wise.

Powerwall doesn't isolate your home from street power.

Powerwall has a noticeable service interruption (3-5 seconds of blackout) when it kicks to off-grid.

Like, come on brah.

Thanks for the top of the brainstem feedback guys!
