Blackouts are normal where I live.
Since I lost my eyesight I haven’t been able to get work so I go out with my friend Georg Squirrel every day and bag newspapers just to get out of the house. (Since I am blind I don’t need a light to see what I am doing and he can drive before sunup.)
A couple weeks ago we had an ice storm which is unusual this time of the year.
I come home 6:00 am no hydro.
Not a problem I start the coal man and the barby.
I make myself a coffee.
Now my neighbor a single mother with three wee ones, I go over and ask if the kids would like a hot breakfast.
You don’t just help yourself when your prepared.
It would work if we had more sun.
The next town north of me is Dundalk Ontario Canada the highest inhabeted point in ontario altitude wise.
Then there is the other problem.
Where I live a funny thing happens if you put something out in the front yard with a sign on it saying “Free to good home” or “Free”.
It will sit there until large garbage pickup day.
But put something on the front yard with no sign on it and turn your back for thirty seconds, it is gone.
I could just see me going into the house to tinkle and find my lunch gone when I get back thirty seconds later.
Pure sine wave inverters will work everything.
Can cost twice as much as modified sine wave inverters, small inverters start at $100 for a 150 watt.
Are less surge tolerant, (1000 watts run 1200 watts surge)
Some pure sine wave inverters are as little as 60 to 80% efficient, (1400 watts in 1000 watts out)
Modified sine wave inverters don’t work everything.
Some induction motors and some electronics won’t work everything else works fine.
Cost half the price of pure sine wave inverters, small inverters start at $15 for a 75 watt.
More tolerant to power surges, (1000 watts run 2000 watts surge)
Can be as high as 90 to 98% efficient, (1002 watts in 1000 watts out)
To be more specific almost all power tools and vacuums are made with AC/DC motors, they will run on batteries or any inverter output some just not as efficiently as others.
Many single phase induction motors will work with modified sine wave inverters many two phase and three phase induction motors won’t.
Lights and heating elements generally don’t care which, your electric stove as an example.
Electronics are a throw of the dice.
One thing you can do is get a 500 watt modified sine wave inverter for as little as $30.
Depending on how modern your house contents are this should run almost everything in your house that does not cook and try them one at a time.
Then you will know what needs a pure sine wave and what does not, buy for what you need.
If you need 10000 watts to run your home 5000 watts pure sine wave and 5000 modified sine buy that.
If you need 3000 watts pure sine wave and 6000 watts modified sine wave buy that.
This way you get the best working for the best price and the best efficiency.
After working with Inverters buying is cheaper and easier than building if you don’t have a mountain of cheap parts.
Cheap inverters
Under 5000 watts mixed systems cost the same as pure sine wave systems, so if you must have a pure sine wave inverter, go all pure sine wave inverter. If you don’t need pure sine wave go modified sine wave inverter, it costs less, is more efficient, and is more surges tolerant.
5000 watts pure sine wave inverter $1000
5000 watts modified sine wave inverter $500
10000 watts mixed system $1500
10000 watt modified sine wave inverter $1000 and up
10000 watt pure sine wave inverter $2000 and up
