Defcon 4 Warning

[pechan]

Hey,
I Started to have a problem with my classic 250 today.

Background info:

5 Classic 250s on Solar and 1 so far on wind.
16,000 watts of solar.
4000 amp hour bank @ 48 volts.

One of my classics is giving me an error, I made a video of the problem that repeats itself every 2 minutes or so.
See full problem @ the 1:09 mark:

I can't get that video to load properly seems to only be partially there?

Maybe its me?

Tom I think he means when the screen goes red..., at the start and ~ 1 min in...

Watch closely, when screen goes red , small box appears, FET drive error, and FET temp is 45.9 degrees (C)

I mean I cannot get it to play. Period.

No matter, I probably cannot help anyway.

Oh, Santa has blocked your machine so no surfing today...

The Local App could probably use some new wording.  that might actually be "OCP" or
Over Current Protection occurring.  Depends on the age/version of your Classic
and the firmware on it.

what is either the serial number or firmware date/version in that Classic ?

Has it been working OK for a while and this just started ?

If this is just an OCP, maybe you have some large battery side loads that
are turning on ?  That might cause this, or at least, OCP's.

BTW, I could see your video just fine here.

FYI, I was also able to see the small popop with "Defcon 4".

Could it be a localapp bug , let's suppose, when it gets some out of range value? Or possibly a mini-sweep? I would try to isolate that classic to log onto a different localApp and see if you can still reproduce.

[boB]

Still would be good to know how old the Classic is and/or firmware version as
well as if you notice large loads coming on when you see the message.

Does it re-occur many times around the time you see it ?  If so, you might
also look at the MNGP to see if it is also giving a message in the status
screen.

Is the Classic turning off momentarily when this happens ?

The Reason For Resting number would also be helpful maybe if it does
go to Resting at this time.
