[RE-wrenches] Conext SW Mystery

[Ray]

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.
