Re: [RE-wrenches] Generac EcoGen 6

[Foxfire Energy]

I'm thinking if this Oopsie just started since the battery swap, it's most 
likely a connection issue.. maybe a wire got tweaked and shorts that start 
circuit somehow

Re: [RE-wrenches] Generac EcoGen 6

[Dana]

Thia could be rodent related I suggest a continuity test. I have seen this
many times on gens out in sheds. We have had to run the 2 wire gen start in
MC several times on older installs with heavy rodent populations

Wrenches,

 

I have a 6 kW Generac EcoGen (1,300 hrs on it) with a new problem. 

. After swapping in a new battery the other day  the generator now
starts and runs when its start switch is positioned to Auto.

. The OutBack inverter w Mate2 is not calling for an auto start.

. Even when the EcoGen is disconnected from the off grid house it
still starts and runs every time the start switch is set to Auto.

 

How do I clear this problem and get this gen back to normal?

 

Thanks and Happy New Year,

Dave

DAVE:
If you have not already gone down this path, there could possibly
  be a short somewhere on the normally open 2-wire start wiring. Try
  temporarily lifting these conductors in the generator enclosure
  and see if issue goes away.

Re: [RE-wrenches] Conext SW 4024 with bad firmware

[Hugh Piggott]

hi Lou,

I don’t wish to contradict this version of events but if true then it will make 
the inverter unsuitable for most generators.  Here is another scenario I have 
seen a few times that looks similar but can be fixed.

The inverter charges the battery etc. and decides to turn off the generator.  
It disconnects.  It may or may not have its own “cool down” time for the 
generator.  It then tells the generator to stop.  At this point the generator 
control circuit may decide to run a further cool down period.  Meantime 
incoming AC voltage is still visible to the inverter.  The inverter may then 
decide that it is obliged to connect to this running generator.  After any 
chosen “warm up period” it may go ahead and synch with the running generator 
and start to draw power just before and during the point where fuel is shut off 
and it dies.  This causes power quality problems and errors in some inverters.  
Maybe better firmware could fix this.  Victron inverters are designed to 
disconnect on a falling voltage every time, and they do so gracefully.  With 
SMA inverters and Outbacks it’s better avoided.

The best fix for this is to make sure that the generator does not have its own 
cool down period.  If you can access and edit this parameter in the generator 
this is best.  Another fix is to set a longer warmup time in the inverter 
software but this can cause issues where the generator is being started to meet 
a high load.  In the case of an SMA inverter you can get a fix to it using 
“genman mode”.

I just wonder if you have witnessed the process and checked whether the 
generator’s own built-in cool down period could be the cause.

cheers
Hugh
