<br>
<span style="font-weight: bold;">So yes looking at the 5 sec has me
switching back to a trusty Radian - <span style="text-decoration:

style="text-decoration: underline;"><span style="font-weight: bold;">ing
it may not work.</span></span><br>
<br>
And you are right Ray - Outback is careful to rate the "overload
capability" in KVA rather than KW due most likely to voltage sag of
course.<br>
<br>
<span style="font-weight: bold;">So this 53 LRA 2 HP motor - if I can
only trust the 5 second (50 A) might not start - especially with other
loads on the system?</span><br>

<p>I only look at the 5 sec and 30 sec surge ratings to get an idea
what an inverter can really do in the real world. All those
millisecond ratings/ in rush current specs won't get a pump or
motor started, and will basically just get you into trouble. The
reason they have those ratings in amps and not watts, is that the
voltage craters during that 100mS surge.<br>
</p>
<p>I can't tell you how many times we tried to start a pump,
compressor, or large table saw, and the inverter just shut off,
even though the "in rush current" was within the theoretical
inverter capacity. Actual Wrench list testimonials are much more
valuable than those arcane specs.<br>

<span><span style="font-weight: bold;">Hey There Wrenches,</span><br>
<br>
So be advised that after a little research the SW dual stack
will NOT double the surge ratings of a single SW.<br>
<br>
But that brings me to my second question:<br>
<span style="font-weight: bold;"><br>
</span><span style="font-weight: bold;">What inverter surge
rating should one refer to when looking at maximum Inrush or
LRA - 1ms? 100ms? 1 se</span><span style="font-weight:

<span style="font-weight: bold;">Your</span><span

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

<br>
So I recently built a power trailer with a single 4 KW
(4048) Schneider SW for a client with a moderate cabin
lifestyle.<br>
<br>
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.<br>
<br>
<span style="font-weight: bold;">The SW has the following
surge capability:</span><br>

Can I be confidant that 2 stacked SWs will start this
baby?<br>
<br>
<span style="font-weight: bold;">Any experience with
similar macerators - or simply educated guesses</span><span
