[RE-wrenches] OB Radian / FM60 grid tie mystery

2024-08-18 Thread Kirk Herander via RE-wrenches 
Hello All,
.
I have a Radian 8048 system in service for over 10 years now. It sold back
quite normally until the last several months -3.- FM60 CC's are set to grid
tie mode and  viewable and programmed from the Mate3s / OpticsRE. This
issue loosely correlates to replacing one of the CCs several months ago.

Trouble is all -3- charge controllers are almost always in a float mode.
The radian does sell, but at a small KW compared to what it used to before
the frequent float mode started popping up. If I remember correctly,
ideally the CCs should always be in bulk charge when sellback occurs.

I have the CC and inverter charger float set to about 1 vdc higher then the
inverter's sell volts, as I believe was recommended way back when. Hard to
understand what changed, but something did. I've checked the relevant
setpoints many times and can't find anything obviously amiss.

Does a sell mode tech note paper exist still for the Radian system? Did it
ever? Any ideas would be greatly appreciated.

I had a similar problem a while back and it turned out to be the FNDC calling 
the shots.. Unplug the FNDC (if you’re using one).. see what happens.

Re: [RE-wrenches] OB Radian / FM60 grid tie mystery

2024-08-18 Thread Nick Lucchese via RE-wrenches 
You're observing this on all three controllers or is the reduced sell back
off by a factor that would correlate to the newest controller you swapped?

Did you calibrate the new controller while the PV breakers were all off? I
still come across new FM80's that require utilizing the entire .5vdc margin
to match my Fluke.

Though it's not a solution can you temporarily raise the bulk setpoints of
all three to verify expected outputs?

It does seem like there was a document on proper sell back settings
somewhere.

Good luck, Nick

Looks like its only programmable directly on the Mate3s, not in optics RE.
Or maybe I haven;t found it yet.

You are all the Outaback wrenches but with Schneider before you reset 
the defaults, you should just do a complete DC power down.  Just in case 
it is a stuck bit in config.

Does a sell mode tech note paper exist still for the Radian system? Did
