We have a 2000 W Heart inverter/charger and a Xantrex remote panel with a "load sharing" provision. This function insures that the rig will not draw more amperage than the shore power breaker can handle.
My remote can select from 5 amp to over 30 amp in about 5 steps.
My question is this, does the load sharing setting impact the rate at which the house batteries can be recharged by the generator?

If you turn your generator on it should turn off the shore power and run everything off the generator only.

YES, a low Power Sharing setting will slow charge rate on shore or generator.
(i.e. anytime the inveter/charger sees an external source of 120 VAC power.
So, set it LOW when on shore power (low battery charging is easier on them AND you have more available amps for other 120 VAC items).
Set it on highest rate when running the generator for quick charging when dry camping to minimize recharge time.

As others have said, load sharing will reduse the apmperage on the charging side of your inverter. When in load sharing, the inverter will allow ac amps to pass through the unit to your appliances etc. If that draw exceeds what you have the load sharing set to, the inverter will automaticly ramp down the charging mode. I have also found that if the batteries are very low, and load sharing is set to max (30 amps) there is apossibility of overheating the inverter. This will cause it to go into fault and trip the 30 amp breaker on the inverter. Depending on the model and year of the inverter, this will cause the charger to stop completely and MAY disable the pass through power also. I saw this happen on my houseboat where the battery bank id vlarge (12 trojan 6 volt L 16's), and the frig shut off. Quite the ordeal when I returned. Now when I leave I set the load sharing to 20 amps. No more overheating, and the beer is always cold.

NO, that is not the function. The other posts are the correct function.
An EMS system DOES have that function. Doug

If your inverter shuts down due to overtemp, you have a problem other than the load share setting. The inverter is designed to perform on all the available settings.
I know some manufacturers (Monaco for one) locate the inverter in an unvented compartment which can result in overtemping when working the inverter near max but that is not the fault of the inverter.
An inverter located in free air will not overtemp (regardless of settings) unless there is a problem with the unit.

My 2007 has a vent in the wall right next to the inverter intake and has a 4" fan on the other wall controlled by a snap disc in case the compartment overheats. Came this way from the factory..

SacsTC,
Where is the cover for your ATS? That is a lot of exposed 120 VAC wiring there.
And indeed, an inlet from a clean dry compartment and an exhaust fan high in the compartment is a good idea.
I have also seen the inverters mounted (incorrectly) high (hot area) in a compartment rather than low (cooler area).

I was replacing a 2000W modified sine with the 2800W pure sine shown in the pic. The 2000 had breakers built in and the 2800 does not, hence the new panel with breakers. Cover had not been installed yet at the time the pic was taken.
My wife takes 1000's of pics every time I do something.
