The 2000 Xantrex (SP) in our Alpine has three round white fuse (breaker) resets on the front panel. Two I believe are labeled 25 and the third 35. I don't see these mentioned in this thread. IIRC Patty once lost power to some outlets and I reset one of these 25 amp buttons on the inverter, and all was good.
Then again, I may be barking up the wrong tree.
