The more common term for the unit is a solar inverter or off-grid inverter.

I run a few of these on an off grid property and they're totally fine. I would be wary of a cheap no-name brands. I'm also be wary of running extension cords all over the place.

If you have the space (a mechanical closet?). I'd suggest getting a separate inverter and charge controller. These all-in-one units have fairly high idle inverter draw.
