Cleaning ICE driven alternator power
petect:
I'm not sure where to post this, so feel free to move it.
The power was out for about a day, so I fired up the old generator (3500 W ICE driven ) and hooked it up to the panel - All precautions were taken. Since my portable radio didn't survive the fall off the garage shelf I turned on the ac powered radio. The noise it made told me it wasn't happy with the juice it was being fed. The gen…I know alternator owner's manual said it could damage “sensitive electronicsâ€.
I looked on ebay and the power conditioners I saw seemed pretty expensive. I'm always amazed at the boards / boxes people here find for every occasion that cheap too. So does anyone know of anything I can get to clean up the power for my tv, dvd player, radio? 100 watts total should do. MINIMAL assembly is a must . I would plug it into a wall outlet and plug the "sensitive" stuff into it. The rest of the house can get by with the dirty juice.
Storms can knock out the power for a couple weeks or more, and I might be looking for more entertainment than feeding the wood stove.
Thanks in advance…….Pete

One of the drop dead easiest ways (may not be the cheapest) would be to find a UPS system. APC , MCG, etc. go for a system that is above 1000VA , you can find them out e-bay pretty easy. Plug that into the generator output , plug your stuff into it and you're set.
I would get much anything lower than that otherwise you run the risk of overloading the thing.
NOW, if you get one that's cheap, plug it into their wall outlet before handing over the cash. Let it sit plugged in for say 1 min, then unplug it from the wall. It should beep, if it last for a minute or two, that'll tell you they unit should be okay. IF it dies, the internal batteries are toast either from age or,,,
Then replacing those batteries with new ones can be easy too.
BTW: This is what I started out with, doing.
Hope this helps

Go double conversion. I would not trust any UPS to filter noise. The output of most UPS's has a lot of nasty harmonics because they are only designed to run a computer for a few minutes until either the power is restored or the computer does a controlled shutdown.
For double conversion you need a small battery, a true sine wave inverter and a 13.8dcv high amp switching power supply to run the setup. The battery is not backup, the setup is run by the output of the switching power supply. The battery just stabilizes the voltage enough that the UPS can operate.
Here is what I did after the local linemen trying to upgrade the grid fried a bunch of stuff switching lines live.

Could try one of these inline. I use them to clean up switch mode power supplies that put out a lot of hash and RF https://www.digikey.com/product-detail/en/curtis-industries/F1300AA15/364-1195-ND/2766360 Mount it in a box with a cord and an outlet.
