<BODY lang=EN-US bgColor=white vLink=purple link=blue>
<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><FONT size=2 face=Arial></FONT> </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><FONT size=2 face=Arial></FONT> </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><FONT size=2 face=Arial></FONT> </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><FONT size=2 face=Arial></FONT> </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>
