Re: [RE-wrenches] Xantrex SW 4048 inverter and Frigidaire

[Allan Sindelar]

Dave, This was a Wrenches discussion topic, somewhere between 2001 and 2005.There was a fundamental incompatibility between the SW series and the electronics of certain new model washers. 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. We only had one experience with the issue, and it doesn't offer a useful solution. A Y2K installation with dual SW55548s wouldn't run a Frigidaire front-load washer. 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. Just yesterday there was a thread here on "charging multiple battery banks" dual systems, 24 and 48V, sharing a switched array. The 24V was a SW4024. 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.
