[RE-wrenches] New Washer - Old Inverter

[Sindelar Solar]

Lou,

This was a not-uncommon issue that would occasionally arise with 
specific washers and the SW series. It often came up with Y2K 
installations. It has nothing to do with voltage /per se/, and the 
inverter is working as it should. The SW is true modified-sinewave (with 
something like 28-42 waveform steps per half-wave). The problem is that 
the electronic controls in the washer aren't compatible with the 
waveform. In short, three options:

1- Sometimes a large electrolytic capacitor across the inverter ac 
output terminals will work. I have seen it work but not always.

2- Try a different brand of washer.

3. Upgrade the inverter to a sinewave unit.
