Run AC's from Inverters or not

[travelite]

Chuck,

I'd check menu item 11, "AC Inputs", on your inverters. Scroll down to "Set Gen Amps AC". CC_Guy brings up a good point. The inverters will try to augment the power provided by your generator if the generator load exceeds the configured setting in "Set Gen Amps AC" under menu item 11. Could it be that someone set this parameter artificially low, for instance, in your case to 15 amps? If so, then the inverters will supply the additional power needed to power your air conditioners, and the inverters won't let your generator supply more than 15A per leg (as seen by your inverters). In your case the inverters are powering the air conditioners on a sustained basis because the 50DN alternator is charging your batteries. It's confusing because the inverters Bulk or Float LED will be 'on' even though the inverters are not charging the batteries. If you look at your "Inverter/Charger Amps AC" meter it will read negative indicating that current is flowing from the inverter to the loads. You might try reprogramming menu 11, item "Set Gen Amps AC" to the amperage capacity of your generator, or simply set it to 60A which is the max you can set it to. This should take the load off your 50DN and put it on your generator and allow your inverters to charge via the generator.
