The CSW is for a small cabin. Anyone living offgrid with normal loads should use an XW and they will not have to deal with any of this. It has been that way since 2006.

Anyway he had a well on a 5 hp. freq drive and a very big tall 6" bandsaw, trace/Schneider said no way could there stack do the job and it was larger. Outback on the other had said no problem and for years after that PS-4 ran the well, the saws and now the finished home. It is interesting that Schneider was not willing to do what Outback could, they must have something in there root programming preventing the stacked surge. Some like Chevrolet, some like Ford, l have done rows of Radians and lm sure some out there have the same with other manufacturers. It's all good data for all of us.

But that brings me to my second question: What inverter surge rating should one refer to when looking at maximum Inrush or LRA - 1ms? 100ms? 1 sec? Your engineering wisdom welcomed!

If you do this, make sure but SW's have the latest and same firmware. There were problems with stacked SW's early on in their development.

But he lives on a high hill and even though his 2 HP Macerator is only rated at 15 amps continuous that baby starts up with a whopping kick - probably close to or at it's 53 Amps Locked Rotor rating. The SW has the following surge capability: SW 4048 Rated @ 240 Volts: Continuous - 15.2 Amps 3700 Watts 30 Minutes - 18.3 Amps 4400 Watts 5 Secs - 29.2 Amps 7000 Watts Max (100ms?) - 41 Amps - 9840 Watts Can I be confidant that 2 stacked SWs will start this baby? Any experience with similar macerators - or simply educated guesses? Thanks!
