Totally sounds like Low voltage disconnect to me. Many, Many times the
generator does not start when it should or connect to the inverter.
I've had 2 systems recently, that both shut down, 1 had the LVD set
really high, higher than the gen start, so that definitely didn't work.
The next one would start the generator when required, but the generator
voltage regulation was incorrect, so the inverter would never connect to
it. Thinking the Ecogen is going to save the day is going to be recipe
for disaster; over the years I've come to despise the Ecogen. I'm
seeing 50% failures, and some of the failures are catastrophic, complete
engine failures. I don't have a suggested replacement, other than go
big enough (+20 kW) to get into the 1800 rpm water cooled equipment, or
just get a decent portable. At least with a portable, you can haul it
in for service.

This is a strange one. I have a Schneider SW 4024 installed in a
remote area of Colorado. Cold and high altitude. Since the fall
every time my customer has gone out to her cabin she noticed that the
inverter is off. She proceeded to turn the unit back on by pressing
the button on the SW. There are no error messages, no tripped
breakers. She has no issues with the system when she is there and
leaves the system on. Next weekend rolls around and she comes back
out to find the inverter off again. Schneider tech support seems to
feel that the inverter is turning off on its own due to low battery
voltage. But there is nothing in the log that shown this. And there
is a Ecogen 15KW installed to protect from ever seeing the low battery
cut off.
Has anyone experienced this? My customer always comes ont on a friday
and seems to believe the day of the week has something to do with this
or this be cold induced? It is rather pressing since winter is in
full swing and a turned off inverter can mean frozen pipes.
Any help out there?
