Re: [RE-wrenches] Outback Radian transfer time

[jay]

HI Eric,

Check that the transfer delay is as short as it can go, about 6 cycles

You might raise the lower voltage limit from 108

Check to make sure all the voltage readings on each inverter are as close as 
possible.  A real weakness of the OB platform is that you have to calibrate 
each item:  

And depending on how you have the power save mode configured, if might be that 
if you can get the generator to drop out with just 1 inverter active that might 
eliminate the transfer delay issues.

Let us know what you find.

Re: [RE-wrenches] Outback Radian transfer time

[Howie Michaelson]

Not sure about the radians (I've rarely used them) but with the VFX series,
that symptom can sometimes be avoided by programming a cool down period so
that the inverters drop the generator while it is still running at full
speed.  Alternatively, by narrowing the generator voltage window at the
bottom end, the inverters will potentially drop the generator connection
before the voltage output gets too low as the generator shuts down.
Hope this helps,
Howie
