Hi BFL,
I've had a similar concern... When I turn on my battery disconnect switch(es) there is a large inrush current when the capacitors in my inverter charge. In an effort to reduce arcing & pitting of the contacts in the switch I built a simple/cheap push-button activated pre-charge circuit that allows the cap's to charge slowly through a high-current resistor before I close the battery switch.
Of course this does nothing on the AC side of the inverter/charger.
