What is the triggering for utility charge? % or volts or time of day or?
I have seen this with offgrid generator use. It has to do with the rebulk volt setting being too low in relation to when the client started the generator. Their intial fix was to unhook the mate and plug it back in. That reset the internal counter and it would charge. We figured it was a bad mate. Tried new firmware, new mate no change. We connected it to optics and OB did figure it out.
If the generator started above the rebulk volt it wouldn’t charge. If it was below rebulk voltage it would charge.
The fix was to raise the rebulk voltage above whatever volts you might start charging at.

It isn't in sell mode. The system is 2 or 3 years old, and has had this issue before. Outback couldn't figure it out, and then is started working normally.

Is the radian connected to grid sell?
If so then I'd say yes the higher grid voltage is preventing connection.

Jay,
It was a problem that surfaced before. Outback tech support was unable to figure it out. Then, the problem went away. Recently it showed up again.
For the last couple of days it has been connecting normally. The voltage has been 250 VAC or lower.
I know that most direct grid tie inverters can go to 264 V. I wondered if the Radian might be limiting voltage to protect loads. Just a theory based on the reading of 251 and higher when the inverter would not connect.
Thanks,
Drake

Drake I forgot to ask, but I'm thinking this is a new problem on an older system that was working normally?

I'm not familiar with Outback defaults but most inverters I've dealt with have a grid tolerance of 10% +/- so 216 to 264VAC.

Hi Jay,
The inverter won't even connect to the grid. It stays in the state where it is sampling the grid, AC in light blinking.
Is the default high voltage for the nominal 240 V 280? (IE 140 V X 2).
Thanks for your help.

Hi drake
The early mate 3 has a glitch which I think they changed in the 3s.
You e got to set the rebulk volts above what you want it to charge at.
IE if the battery volts don't get below the rebulk volts it won't charge.
So if your shallow cycling the batteries it's common it won't get below the rebulk volts. If you're deep cycling it usually will with default settings
The default high voltage window for ac input is default at 140v.
Hope this helps
