I have the Xantrex Freedom inverter charger 2500 watt. Everything is okay but some things just don't run good on modified sine wave. Does anybody make a gadget that would change modified 120v to sine wave?

The gadget you need is a new inverter.

IMO just get a second inverter that is PSW. I have a 1000w PSW wired over to the 2000w MSW inverter right beside it next to the battery bank. The 1000w inverter gets to the battery via the big inverter's fat wires.

With only the one big inverter, the shore power cord went into that for whole house (converter off)

Now the shore power cord goes into the 1000w PSW inverter for whole house (the receptacles etc) and a second wire (extension cord) runs back from the big inverter to where the shore cord goes into the trailer at the back. That cord is for the microwave, kettle, and toaster

If you want PSW for the MW you have to get a big inverter, but we don't need PSW to run our MW thank goodness.

Maybe, but it would be as or more expensive than just getting a new inverter.

Would love to get a new sine wave inverter charger but 1300 dollars causes me to pause. I thought somebody might make something cheap that would condition the wave form. I'd get just a sine wave inverter but I need to keep my charger setup working. I think I need to convert 120 volt modified to 120 volt pure sine. Maybe I'm not thinking straight. It's been know to happen before.

$1.300 would be for a really big PSW. What do you want to run that needs PSW that needs such a big inverter? Most things exept the MW only need a small inverter that is more like $300 or less

Mine is an inverter charger, so to replace that is in the neighborhood of $1300. I have a residential frig and convection microwave that need some watts.
