As best I can tell, it's not related to the size of the load, but to
the zero crossing of the waveform. I have also seen that the Magnum
will start surprisingly large loads because it allows a greater AC
voltage drop - I have seen down to 80 VAC on a 120 VAC output, where
other inverters would hold to a greater voltage drop limit, but
would shut down due to overload instead.<br>

to start loads that other equally sized inverters could not

interfering with the controls? I have started a two HP pump

<div>In the case of the Splendide washer/dryer (see link
in my previous post), it was definably the Magnum
Energy inverter. I could not start that load (no pun).
Since then we have tested several inverters with these
washers and all work fine except for the Magnum. I
must say that, other than this one fault, the Magnum
has been an exceptional, US made inverter and I
heartily recommend them.<br>

I have experienced this as well, but have no
solution to advise. My last direct experience with
this was about four years ago, when we installed a
system using a Magnum 4448 inverter in a home
system in which a high-efficiency
electronically-controlled hydronic boiler was also
installed at the same time. The particular boiler
proved unable to start up reliably on the
inverter, but would run reliably off of a
generator. Initially we assumed that the problem
was due to incorrect wiring by the heating
contractor (the AC input line and neutral had been
reversed). After this was corrected the problem
persisted. Before we could dig deeper the
contractor changed out the boiler to an equivalent
model of a different brand. The problem went away.<br>
<br>
You may end up having to either change the
inverter or change the boiler. Magnum's tech
support showed some interest in pursuing this,
even attempting to duplicate the problem, but we
never got that far. You might wish to contact them
about this - it's a legitimate problem.<br>
<br>
On a related note - has anyone had any issues with
powerline-carrier lighting controls run off of a
Radian? We haven't installed equipment yet, so
have no way to test until then. We're supplying
uninterruptible power to an upscale residential
observatory that will have this type of lighting
control. We have cautioned the GC that there's a
possibility of incompatibility, and no database of
collected data out there, and we don't assume
liability for incompatibilities. But it sure would
be nice to know if anyone else has seen issues. I
don't yet have a lighting brand.<br>
<br>
Thank you,<br>
Allan<br>

<div>I am assisting in troubleshooting a stand
alone system with three stacked Magnum 4448
PAE inverters. The electric ignition of LP
for the wood boiler will not fire from
inverter power. As soon as we fire up the
generator, the boiler ignites. Has anyone
seen this before? Is there a solution? The
boiler is a Central Boiler E-Classic 2400.</div>
