Are there purchasable inverters that don't squeal like a stuck pig, or is this purely a homebrew project? I'd like to try to silence one of the "adafruit" style inverters, but I'm worried that that may not do the trick. I'm going to have to either have the inverter running basically next to my ear, or *possibly* massively extend the cable to fit in a backpack or something of that sort. If I went that far, though, I'd be making a custom enclosure/battery setup for the lot. I'd prefer to use 12v in that case.
we believe these are the best high-quality inverters that are available - we sampled all the ones that were out there and chose the ones we did after careful testing.
you're welcome to purchase one and return it within 14 days if this is a concern.
