Amos,
I installed an MS-4448AE (not PAE) in late 2008 that wouldn't fire up a
Buderus hydronic boiler. Ultimately it was replaced with a Lochinvar and
that solved the issue. Magnum asked for the Buderus for testing, but
that never happened, as once the problem was resolved by the heating
contractor it was forgotten.
This issue was addressed on this list around 2/10/09, if you'd care to
peruse the archives. To make it easier, I'll forward you a few of the
emails, including a compendium of Wrenches responses, off list.
I'll also note that I have used a MS4024AE in my own home since 2010.
It's been flawlessly reliable. However, every time the fridge comes on
the lights flicker, especially one chandelier with 6 40W incandescent
bulbs on a rotary dimmer. And one client with a MS4448PAE I installed in
2011 complained that while the inverter worked well, anything in his
home with a clock built in ran slow and had to be reset at least monthly.

I also have a new (7 month old) PAE system with 2-4448 Inverters
(stacked) that we are having some strange issues with. The most
troublesome issue is the new Rheem wall-hung LP instant water
heater/boiler is throwing an Error Code 12 which is supposedly a
“Flame Failure”. It’s a brand new installation with new tanks and
lines and the gas guys have doubled checked everything. We are now
wondering if it might be related to the power supply. The other
indications that it could be related are flickering lights, a 12V
battery charger (AC plug in type) that won’t work off inverter power
(but will when plugged into the genny, and I’m seeing a little bit of
wondering in the Hz on my simple Exeltech volt meter.
Magnum recommended a run capacitor on the boiler circuit. I installed
that on Friday and still had the error code come up 4 times over the
weekend.
Any thoughts?
Best,
Amos

Long runs of URD direct buried? Just a nick into the metal can
corrode the cable all the way through over time. We use conduit for
almost everything anymore. The savings with URD doesn't pan out,
when you have to abandon the line after 10 years.

I would look at connections first, lug that is not as tight as it ne
we do to be, a breaker failing, outlets that are either push in
wires or have loose connections. Eliminate what you can before
looking at the inverters

Hello
we have a lot of PAE series magnum inverters out there.
One client lately has been experiencing voltage drop and
failure of PCBs in two of his household appliances. I know it’s
common to have some dimming of the lights when a well pump or
other large load kicks on, but has anyone ran across a solution
to alleviate the problem or boost up the voltage / condition
it, in any way ?
I’m not sure if this just happens with low battery voltage, or
always
The inverter is located ~ 300 ft from the main electrical panel
with #2/2/2/4 URD feeders to an outdoor disco, then 8 AWG
copper to the mains panel.
4448 PAE with one string of 6CS21P Batteries.
