if it is possible with power iso i have installed this one on my system. http://standaloneinstaller.com/download-...
You mean create a USB key from Windows ?
Absolutely possible because I successfully created a Big Sur USB installer on my Windows 10 PC with UUByte DMG Editor.
However, you should download the macOS dmg file first. This software can quickly burn DMG file to USB and you will get a bootable macOS USB disk in a few minutes.
BTW, it also has a Mac version you can try out.

I'm thinking of using this method to revert back to an older os due to my mac slowing down with Sierra. Will I be able to install just Yosemite or el capitan? Without installing previous os upgrades? This way I can have a fresh mac book.
Hello,
Yes you can but with this method, we must make a clean install.
So, please sure you save all your data to another hard drive.
