Xantrex 458 Freedom "filtered" modified sine???

My GE fridge has worked on a 458 MSW for the last 19 years. I don't know if you have a picked a fridge yet but the Samsung units are reported to run well on the MSW unit as well. There are things that won't well but you can always run your genny if necessary. Your fridge should work just fine. Check with the manufacturer to see if their unit will run on a MSW. Just tell them you plan to use it in a solar powered home to avoid the RV confusion.
