The function of inverter paralleling is to assist a generator in the STARTUP of a load.

Such points as DUTY CYCLE must be applied toward the inverter. X time for X watts of paralleling support. Boosting startup is supposed to take place in seconds, not minutes or hours, regardless of the size of the battery bank. Check with OEM if you question this.

Winner winner chicken dinner!

If I can imagine for a minute - my use of a magnum inverter would be to boost the startup surge of an A/C to allow use of a single 2000 watt inverter/generator, not power it for hrs. However, would the converter section draw too much while recharging the battery, can it be set to monitor the total power use and limit its charging so that it doesn't overload the generator?

There is no converter section. There is an inverter section, a charger section, a transfer switch, a few protections.

Yes it can be set to limit the incoming AC amps and use the batteries to provide inverted power to make up the difference in load up to it's maximum load support. YES it can do it continuously.

This is basically the same thing that a grid tie inverter does......just in reverse.

Grid tie:
- Send all inverter power to house
- If excess inverter power, send to grid
- If not enough inverter power add grid power to cover loads

Hybrid inverter charger:
- If shore power present use it
- If excess shore power available also charge batteries
- If not enough shoe power add inverter power to shore power to cover loads

AND no imagining necessary, no speculation necessary. I provided the link above where you can download the well written and lengthy manual FOR FREE and read all about it. Furthermore, if you still have questions, I've found Magnum technical support and sales staff to be very helpful and responsive.

All that said, what you mention about adding in load to cover shorter term loads such as air conditioning is the most realistic RV configuration. Continuous loads above the incoming shore power would eventually deplete the batteries. Where as using it for load support for seconds, minutes or even an hour or two hear or there would still allow the batteries to charge when your loads were below the incoming shore capability.
