There are a couple things on the Magnum inverters that you will learn about after using one that really need to be corrected. DO NOT backfeed them, they are not protected like most other inverters. Back feed them and BAD THINGS WILL HAPPEN! Read that as expensive.
Also the split phase 120/240 inverters are slow to recover from a voltage drop. I have never noticed this on the 120 volt units but I don't have any large loads anymore so I would not see it like someone with a well pump or other large surge loads. I have had several calls about this from customers and it is real. If this is a problem or not seems to depend on the customers attitude, but it can be annoying. At least they are still made here, and the service is good!

Magnum MS4024 (120V single phase output) has neutral/gnd switching in the transfer switch of the inverter. It is ETL listed to UL458 (mobile inverters) AND UL1741. The MS4024AE is a 120/240 split phase inverter intended for AE use (non-ground switched) It is ETL listed to UL1741. Weight is an issue as well as > space.
