[RE-wrenches] Xantrex SW 4048 inverter and Frigidaire

[Tump]

As for the older SWs we installed the cap on the output side, that being said I have seen GFIC outlets causing problems but I have not seen these issues w/ my SMA SI. Sounds to me that; being the professional you are, suggesting the replacement of the older SW with something that may be less frustrating ( new inverters and their firm ware upgrades, less frustrating yeah right!?) better performance and eliminating costly washer repairs. If I were to try and rectify the issue, then I will usual start w/ the removal of the gfic, cap on the ac output, (we would just installed it on the questionable load's circuit,0 OR offer a credit for the old SW and try to sell them the SMA SI 6K inverter and then work your way down to their budget.

The early Maytag Neptunes and front-loading, electronically-controlled Frigidaires had issues with the mod-sine waveform of the SW series. I looked in my archives but have nothing saved about that. You might find the original thread in the online archives. If the "expensive controls" include control boards or related, this could be an ongoing issue with this combination.

Adding a large power capacitor across the input (per Wrenches and possibly Xantrex tech support advice) didn't solve it; switching the washer circuit to the other inverter did. We never did figure that one out.

Many of us still care for systems based on that series, and have good respect for it, but as they get older and support gets tougher, the energy seems to be shifting toward replacement.
