converter when I use the inverter ?
Thanks for your thoughts!
Tough to answer your questions accurately without seeing how everything is wired. Do not assume that the 120VAC for your entire coach is available thru the inverter. Most are not wired that way, but have the 'inverter circuits' run thru a separate 120VAC sub panel, as 2000 watts is roughly 16.6 amps or about half of the 30 amp service that your coach has.
If your inverter has an internal transfer switch (like all Magnum units), the inverter will know when 120VAC is present and will not invert while connected to the grid. OTOH, if it did have an internal transfer switch, all of the circuits in the coach, including those marked 'inverter' will receive power when on grid.
If you have an 'inverter only' device that does not have a charging section integrated into it, then chances are that you do not have 120VAC running in to the inverter, only 12VDC positive and negative in and 120VAC out.
NEC code states that there must be a transfer switch or manual disconnect present that will not allow any single circuit to be powered from 2 separate sources simultaneously.
I would have the wiring checked by a qualified professional who can then make a circuit diagram for you so you know exactly what is happening in the circuits.
Here is a link to the Magnum Energy installation manual for their MS-2012 series, 2000 watt sine wave inverter/charger. It will give you some idea of what you should be dealing with: http://magnumenergy.com/wp-content/u...Series_Web.pdf
