I have a Magnum installed in my camper. You cannot sleep in there with it on. That's just one model, but I've listened to a couple of others and they are similar. Tech support said "yeah, they do that". The weight is a consequence of the 60 cycle operation, which requires big transformers. And the state of charge counter draws about 80 ma by measurement, 60 AH/month not accounted for (tech support says, "yeah, that's the way it is"). Their remote control has very few settings and features compared to Mastervolt or Victron. The transfer relay is rated at 2/3 of the built in circuit breaker rating. Those are observable facts.
Now I've had issues with Xantrex equipment too, the Prosine 2000 that I had failed three times and had some of the same power consumption issues. The Freedom was reliable, but not very efficient and very, very heavy.
I have 6 Mastervolt products on the sailboat, a 100/24 charger, 2500W inverter, 3 DC-DC 24-12 converters, and the state-of-charge controller. In 10 years of heavy use, one DC-DC converter has failed (a mechanical failure of the output terminal), the others continue flawlessly. The inverter, rather than drawing 40 watts idling draws 6. It is silent until a large load it put on it, then it turns on a quiet fan that runs intermittently.
The more recent Victron equipment is high frequency switching. There will be no inherent reliability difference between low and high frequency switching for properly designed equipment. While much is dependent on quality of design and manufacture, it is very rare to get a 60 cycle hum from a high speed switcher....
I respect MaineSail's opinions, but I do not agree with him in this instance. I'm about to install an inverter in the trawler, and I will try a Victron.
