Inverters.
« on: March 22, 2021, 10:43:15 AM »
There are some really big ones out there now. They can run a house useing a low amperage demand. About 40 amps max. As long as you have a good D.C. Source. Like a truck, with a good battery and charging system.   
And the wireing to accomplish this. This would keep your lights and devises on. And your freezers. But not a central air. They are square wave, which shouldn't really effect anything. Some can even do sigh wave now.

Some Texans were smart enough to pull their meters" which is ilegal".  And tie thier generators in there.
Power failures are going to become a common thing now. Even your generators are going to need fuel.

The biggest problem is that people try
to use a house full of electric devices at
once as if they were still on grid as usual.
I see a similar problem with people that
move to the "country " and continue to
waste water on a well or a shaky rural
water service and they just can't figure
what the problem is

Yes, turn off the breakers. And ease back into it.

Bought a 3000 watt Westinghouse inverter from Lowes for backup in case we lose power with these Arizona storms. Just enough power for the fridge and such. Can't hear the thing running at all. Runs forever on a tank of gas. Wished they made em years ago.

Those are running at 1800 rpm, four pole rotors. Not at all like the gas guzzling, two pole screaming banshees that run 3600 rpm. I had customer once who had had bought one way back when. He called me and said he thinks his new generator wasn't running fast enough. I poked my Hertz meter into it and sure nuff, 60 cycles. Good thing, he was about to try and bring up the RPM's.

Careful in Europe folks, they in some places run 50htz. and 240VAC on their outlets. You want to plug in your American device which uses 120VAC, you have to use a converter. They are cheap and readily available, even in some Airports. Don't worry the lower frequency won't really hurt it, not like a much higher frequency would. But things will run a lot slower. Especially American electric clocks, electric tools, that aren't using battery's.

A lot of the bigger Truck stops sell the D.C./A.C. Inverters. They are relatively cheap, and can run from about 400 watts to 3000, that's 3KW. But with them you have to have a DC power source, like a battery which by itself will only run things for a few hours, depending on load. Where a Vehicle will keep it topped off.

My daughter's neighbor in NC had a line cut by some utility company, so the electric company installed some type of inverter mounted on a dolly which ran their house.  I don't know if they changed it out once in awhile or what but my daughter said it was out there for a few weeks.  I had to move it over a bit to make a garbage can enclosure for my daughter, it was only connected to the meter area, I had thought they had piggy backed off my daughters feed, but no it was just a large battery with an inverter.

Still have to keep the battery or batteries , charged in some way. Lorain makes a lot of these like you mentioned, they sell them to the phone company's. They are about the size of a small freezer. As far as connected to the meter area, was that the primary leads or the secondary? Primary " input" would be color coded black and red, secondary " output" would be two large black wires and a white neutral. That's what would be going to a house. Reverse order if all it would be doing is charging some kind of remote battery banks, there are two different types. One with A.C. output, DC input. And the other type, AC input for D.C. output. If going to a meter base would it be only for charging, or for supplying?  You wouldn't be supplying DC on an AC load. They also make Duals, capible of going either way, but they are very large and heavy.

Omega, it sounds like the utilities company put that inverter on that house to keep power going to the house during some kind of extensive line repairs that could take some time. Expecting black outs and brown outs.
And possibly some spikes that the inverter would prevent from effecting the house. I wonder if the house was located at end of line, or close to it.
