<DIV><FONT size=2 face=Arial>I was looking at a scratch pad note where I wrote
25 instead of 55...Yes, it is a SW5548. Definitely not set to "Search"...it's in
"On" mode. I've checked error codes. No "Yes" messages. I am wondering about a
firmware upgrade although I have serious doubt that will clear up the
problem.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I guess I will try the swap and see if that does
the trick.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>On the genny, I try to stay away from genset
service but I can definitely check some of the more simple items like check oil
& coolant.</FONT></DIV>

<DIV class=moz-cite-prefix>Eric,<BR>A Trace 2548 with automatic generator
start? I don't believe there ever was such a thing. I suspect that you're
referring to either a SW4048 or SW5548. If so, your first step is to check the
error codes, some of which are found in Menu Heading 2 (for generator-related
issues) and the rest in Heading 5. Any "Yes" message as you scroll through
them is a good hint. <BR><BR>This inverter is at least 13 years in service,
likely more. Sounds like a pre-GTI Y2K system. The units are remarkably robust
and reliable, but it may well have a glitch in the firmware or
voltage/frequency sensors. The extra inverter is your ace in the hole, once
you determine what the issue is.<BR>Allan<BR><BR>

<DIV><FONT size=2 face=Arial>I have encountered a Trace 2548 in seemingly
good working condition. I was called out to troubleshoot a Grid-tied,
battery back-up system with the following problem:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>- Upon loss of grid power there is about
a 5 second lapse (no power to house) before the BB system engages.
Power to the critical loads panel from the Trace is restored after the
5 second lapse.</FONT></DIV>
<DIV><FONT size=2 face=Arial>- After another 5 seconds the Trace will
disconnect power to the loads. This on-off cycle continues until grid power
is restored.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>After checking voltage & S.G. values,
I determined that the 11 year old batteries needed to be replaced and I
assumed this was the cause of the Trace on-off cycling.</FONT></DIV>
<DIV><FONT size=2 face=Arial>I also found that half of his PV array had bad
BP modules. BP replaced all of the modules under somewhat of a warranty. So,
new modules, new batteries, and a new Outback FM60 charge controller. After
all upgrades I ran through a simulated power outage again and the
intermittent power problem persists!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>He also has gen support enabled - connection to
an Onan "RV Genset BGE NHE (??) - and when I start the genny from the
inverter, by selecting "On" not "Auto", the genset fires right up
but only stays on for about 30 seconds before it too shuts off and enters a
cycling between auto-starting from the inverter and shutting
down.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>This behavior is beyond me. So, I'm seeking
help from the pros. Anyone know what's going on here? The customer has
another Trace 2548, unused, sitting in a box. So, if I needed to I
could swap out the inverter and see if that makes a
difference...?</FONT></DIV>
