When our inverter/charger lost its battery charging function, we replaced it with a Xantrex Freedom 3000 watt unit on the advice of the company doing the work. The old unit was a Xantrex Trace 2500 watts. I asked the company owner why he recommended a Xantrex over a Magnum but don't remember hearing a good solid reason. As I recall, he said they're both virtually the same, just different manufacturers, and he deals regularly with both brands. So far, so good after several years. I will say the Freedom 3000 is much easier to program than the Trace 2500 was.
