Hi Mark;

I'm glad to see you on the list. I really never got a response from you 
though on the SW+ voltage sag issue. ( it was a string you may have missed 
a couple of weeks ago) I will summarize: basically I and other wrenches 
have noticed SW+ voltage output dipping below 100 vac during inductive load 
starting. This is accompanied by the various expected symptoms of a brown 
out, i.e. lights flickering , computer UPS beeping on, etc.
In my case, we have a malfunctioning Staber washing machine that we have 
gone through 2 replacement control boards. Staber insists it is a power 
quality issue. I was really fending for the SW+, until I set my Fluke89 to 
regular minimum capture and found the voltage dropping to 86 vac for about 
a tenth of a second, while starting a circular saw. I checked DC wiring and 
connections, volt drop between the batteries and inverter, AC wiring ,etc. 
I have come to the current conclusion that the new SW+ series allows the 
voltage to dip on purpose to achieve its 10,000 watt surge rating. BTW, I 
have seen these same symptoms on 3 different units, both the SW2524+, and 
the SW2548+.
Please, an official response from Xantrex is needed here. Staber will no 
longer honor its warranty when used with this inverter. This is an issue 
for much of the off-grid market, since many of us currently sell Xantrex 
inverters and Staber washers. Because I sold both to the customer, I have 
assumed responsibility for the entire issue, and will be forced to switch 
out the inverter to an Outback, if necessary. (I have several hours and a 
couple of hundred miles at my cost into this already)
I'm not a Xantrex whiner, I was actually talking up the SW+ earlier on this 
list.
Again, your timely response would be greatly appreciated, as I am returning 
today to this project.
