Hi dons,
The elcheapo at 3000 watts are around 1200.00 (usually plus shipping). After the warranty is up--if it fails the companies do not sell parts. If I could have found a 3000, or better yet 4000 watt, 12 volt dc inverter that did not have a charger and could be repaired, I would have gone that route.
I do not need a way to monitor my battery levels. I have a watt meter so I know how much energy I have used.
I do not need an autostart for a generator, and if I could avoid it I would never run the generator I do own, except to exercise it (which is what has happened since August of 2013).
I but rarely need a better way to charge the battery banks. When I was part time the solar system did well over 90% of the charging. As a back up I had the alternator and dual manually controlled solenoid based charging paths. Finally there is a PD9140 with a wizard for shore power charging. So far, now that I'm full time the shore power is being used more than ever before--but the solar still does the "topping up" due to it having a temperature probe on the battery bank.
I will probably enable the Magnum for charging purposes, but only because it has temperature correction.
What I need the remote for is limiting the 120 volt power input down to something that will not cause a 15 amp shore power breaker to fault from over load. As an urbandocker I most often do not have access to the shore power breaker panel, and knocking on someone's door at 2 a.m. would not be appreciated.

Well, if you don't do shunts, then you are going to miss a lot of what the inverter and the associated controller can do. You might as well buy a elcheapo converter/inverter and be done with it.
Using a shunt will enable functions on the inverter/controller that cannot be accomplished otherwise. You need to spend some time on the Magnum Energy website to see how everything interfaces. Read the manual for the inverter of choice, the different controllers available, the auto gen start modules, etc
