<DIV>Kevin,</DIV>
<DIV> </DIV>
<DIV> Not to add any confusion but I
recently had to re-program the slave in a 2 VFX with Xfrmr system as it was
doing the same thing...the 2 pole xfrmr breaker was tripping when a moderate
load was on. Granted this was not happening during charging
though. I think I changed the slave from OB slave L1 to OB slave L2 and
all was good. It doesn't seem likely the programming in your case would
have been messed with having been working well for years prior. Curious
to hear though of a solution eventually.</DIV>

<DIV><BR></DIV>Have you turned the breaker on the t240 to the off position?
One does NOT have to have that operational for the system to operate
correctly.The old t240 has about the same parasitic draw as an inverter.
Isolate, Isolate, Isolate. If the system functions correctly w/ the t240 off
and the stacking is correct on this q stack disconnect it(the t240).
Otherwise I would remove the inverter com cables and only connect 1 pair of
inverters at a time, reset the mate with the correct com cables connected to
P1& P2. Sometimes something so simple as disconnecting &
reconnection the mate can have quite a benefit. Again I would, if you are
really stuck on having the t240 operational, then try it with each inverter
as a single unit then try the second set of inverters. Disconnect the
#s1&2 inverters and do the same; connect #s 3&4 P1 & P2, to see
exactly which component may be your problem.

<DIV> Wrenches<BR>OK if the X240 blows the fuse which is on the
output of the inverter while the inverter is charging, excessive current
must be passing through from one inverter and back to the output of
another inverter ( a form of AC coupling gone bad). The time delay fits as
the inverter ramps up, I would look at the contactors in each slave as one
may be hanging or ther may be a bad board, easy way to test is to isolate
each inverter and with a amp meter connected at the X240 see if current
goes away in the X240 as it should not be doing much with light loads on
the "House" side of the inverters. The X240 is 25 amps while the inverters
are 50 amps. Sounds like a interesting one to
diagnose.<BR></DIV>Jerry<BR></DIV>

<DIV>Hi Kevin, </DIV>
<DIV>I have seen the X240's trip off like this when theyare
over loaded. When this was happening to us the slave inverters had blown
AC boards and some times Control and FET boards too. We had a hard
time diagnosing this as their green lights were on. Using a
clamp on amp meter on each inverter's AC IN conductor while
charging with the gen set allowed us to compare their charging currents
to each other. Typically the ones with blown AC boards output
would be close to zero amps. So the X240's were doing double duty and
they will smoke too if the inverters aren't delta with. </DIV>

<DIV>Subject: [RE-wrenches] Outback quad stack X240 breaker tripping
</DIV>
<DIV><BR></DIV>Hello Wrenches, <BR><BR>Customer in remote location has a
strange situation come up on an existing system installed (by others) 6
or so years go. Quad stack VFX3648. <BR><BR>Last night gen start was
triggered by low voltage - a normal system operation. <BR><BR>Approx 1h
into charge, they lost 1/2 the circuits in house - L2 de-energized.
Caretaker went to check power system and noticed the X240 breakers
tripped. Tried to reset but it tripped out right away. So he left it as
is and called me in the morning. <BR><BR>Here's what I've been able to
determine today: <BR><BR>- The x240 is installed to bridge L1 & L2
on the load side. <BR>- with master inverter on, 3 slaves off, both L1
and L2 energized so suggests x240 is working. <BR>- within 10 seconds of
generator on and charging, x240 breaker trips (and makes L2 go dark).
<BR>- loads are minor, ~1,000 w of misc lights and such, isn't all
loaded up on one leg. <BR><BR>Appreciate any thoughts to remedy. I'm not
as familiar with this config as others. <BR><BR>Kevin Pegg<BR>EA Energy
