[RE-wrenches] Trace 2248 Documentation

[Travis Creswell]

Thanks Brian, this tells me all need to know.  I had no idea they were that
old.  It helps that there's not really all that much to figure out on them.
These are not the SB models so no battery charger to adjust.  They have 1
on/off and 1 pot to adjust search watts. The only possible thing to adjust
is the search watts.

The FET boards are blown on at least half of the 2248's and looks like water
got a few others.  The survivors are surprisingly strong.  I've set up a
load testing station using 48v input from my own system.  I'm hooking up
about 1800 watts of reactive and resistive loads and running them for at
least 30 minutes.  Just for fun I drug my twin-tank air compressor over
there and to me amazement these inverters start it with barely any
complaining.  It's the hardest starting 120v load I've ever come across and
regularly "over current errors" customer's outback inverters and even trips
breakers in my grid tied home.

Best, Travis

Sherman, set the Wayback Machine to the 1980's....

The Trace 2248 is one of the original line of Trace products dating from the
late 80's to very early 90's. Those "black battleships" were later upgraded
into the "U Series" Trace inverters. Mod-Square wave, and no William, they
were not grid-tie-able.

All I have are a couple of hard-copy spec sheets, hard-copy performance
graphs (load capacity vs time, and power vs efficiency) an explanation on
how to set the user controls for the battery charging section (if it had the
"SB" option), a FAQ sheet about it getting ETL Listing and switching to
white color, and Trace pricelist from August 9th, 1992.

Sorry, no manual. I thought that I had one, but it's not in the archive
file. I'll let you know if it turns up. Check to see if Xantrex still has a
manual for the U-Series, since they are basically the same thing.

Oh..and I found a printout of a Home Power review from 1993 of the 2512
model...written by Bob-O Schultze. Home Power #35

The 1987 AEE Catalog only had the 1512, 2024, and 2132 models in it. No 48V.
The 1988 Catalog had the 1512, 2024, 2132, 2236, and 2248, so that was the
first year that they were available.

Those are 20-year-old inverters. Some of them are probably still out there
working.

If any of this is useful to you, contact me off-list and I'll scan it all
into pdf's and send it to you.

This is the great thing about the wrenches list!  I've got a qty of old
2248's that I salvaged from a tear out job that have a box on top of them
with a small transformer and a circuit board inside and a ribbon cable to
connect it two inverters.  Now I know that this is a set up for paralleling
them.  If someone can use these boxes let me know as I almost recycled them
today.  I've got at least 6 of them.

Anyway, I'm in the process of testing and cleaning them up for resale and
could use a manual for this inverter.  Xantrex's website does not appear to
have one.

Any help would be appreciated.

Thanks in advance.
