[RE-wrenches] 100ms for Locked Rotor Amps?

Fri Jul 26 09:20:05 EDT 2019

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.

for a customer that was building his home, he was milli g lumber from the
home site, l quoted a Outback PS-4 3648, the customer already had a very
large battery bank 2000 amp hrs. at 48 DC nominal. 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. Jerry

So be advised that after a little research the SW dual stack will NOT
double the surge ratings of a single SW.

 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!

 Thanks,

 Jeff

Thanks for the tip! I'll check the firmware.

Hi Jeff, 

I am not going to guess if this will
work, it should. I use XW's because they start anything I have come across.

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.

 So I recently built a power trailer
with a single 4 KW (4048) Schneider SW for a client with a moderate cabin
lifestyle.

 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!

 Jeff
