Greetings Drake, If this hasn't already been done; "Acknowledge" the Event (Fault) via the MATE3 in the Event History and the indicator light should switch "off", as long as the Event/Fault is not actively occurring. Hopefully it is as simple as this to calm the client's concern.
Best of luck. Please let us know if you are able to learn any details about the cause of the issue. Best regards, ----MATT Matthew Sirum P.O.

I haven't been able to make it out there yet to check the parameters. The main reason the client is so worried is that she got a message that I'm not familiar with that said something to the effect that the problem had to be solved before the event light could be turned off. I did not see this personally, and haven't encountered this message before. I will need to see if the manual can shed any light on how to turn off the light. .

I have Grid-tied OutBack Radian GS8048A with MidNite Classic 200 systems in the field, but don't believe I've seen this issue before. (But certainly have seen many strange MATE3 & OpticsRE issues) Here are a few questions that come to mind: What is the Radian "Sell" voltage set at? Has this setting been checked since this issue was reported? Have the Classic 200 settings been checked to make sure they are set where they should be? Does the system have any data monitoring on the charge controller and/or battery system independent of the Radian inverter? If so, any information similar to the Events logged on the MATE3? Does this system have the OutBack FLEXnet DC installed? There could be more data to review to try and get a sense of what the issue may be. (shunt data, historical VDC data, any battery charging via grid?) If the system has more than one Classic 200 are they connected and set up in "Follow Me" mode? Any chance the charge controller or inverter/charger tried to initiate an equalization charge? Does the system have any DC loads or generation sources (other than the charge controller and inverter/charger) connected directly to the battery system or anywhere on the DC bus?

The Radian is selling to the grid and is being fed by a Midnite Classic 200. It has shown two spikes so far, the last one going to 67 volts and lasting 1 second. The batteries are Concorde AGM, 305 AH. Does this momentary spike seem like a problem or a warning of problems to come?
