Average US residential power consumption 909 KwH per month.
That’s 30.3 KHh / day. These batteries are 7 KWh.
You get a few hours for $3K. Hell you get a few power outages a year of that duration, during which time you get in your car and go to a bar to watch TV or go to McDs and use their internet. Helluva lot cheaper than $3K for a battery that will need replacing (and btw, that 3K will have more tacked on for installation).
This is crap.
I don’t think thats correct. 30.3KwH sound awfully high. I use maybe .300-.500 KwH
Few power outages last more than a few hours.
For backup purposes, that should be sufficient.
One of these is not going to run your home 24/7.
I agree. Our peak use is January, bill shows 798 kwh per month, which would be 66 kwh per day. If I’m figuring this right, we’d get a whopping hour of “free” electricity.
January is one of our shortest day months, probably 8 - 9 hours of day light. Half of those days are clouded over for snow.
January is our coldest month with actual temps often minus 30F for a low and 0F for a high.
Like the electric cars this stuff is utter crap for the extreme cold northern tier states.
A propane generator is the way to go with a buried tank.
You’re right, I’ve tracked our usage carefully for years, and that’s right in the ball park.
I just got our power bill and we used 271 KW last month.
If you want to do off grid solar you need to put a lot of stuff on propane anyway. 7KW would run our place in the mountains no problem. Plus you have to remember that with solar panels they are charging all day long. So you run your washer, vacummn cleaner, etc during the middle of the day and you are not running AC or heat off a solar system. You need a woodstove and ceiling fans.
