Also what is this Midnite ?
I am guessing an old Trace thing .

See what they did there.

So after monitoring Rosie and Barcelona .
These are a few things that is not going so well:
1.wbjr is always at 0% after two plus days( I am thinking a firmware update is needed ,was not done as yet)

2.Got a ground fault notification.(Ground fault toroid was installed and activated, Arc fault was not installed because of missing plug on options board).
Additionally,Dc negative to ground bond was not installed.As per my understanding this is created with the installation of the ground fault toroid and board.
Correct me if I am wrong.

Any thoughts on these.

Yes, the stories go back to early 1990s days of Trace Engineering when Robin started a particular, never ending story about the adventures of the Troll, Irving,  and his wife or girlfriend, Mary. It always contained parts and pieces of lyrics from 50s and 60s songs and the ladies that stuffed circuit boards in production loved it when there were new stories to read.  They were all too young to know what the songs were, usually.   So we kind of started to continue the trend but a little differently.  Doug Andrews, an old employee did a lot of what you read on MidNite PCBs.  Doug also worked at Trace.


As for the apparent bugs, I will pass this on.  What quarter of what year (2023 ?) was your Rosie made ?

Rosie is LAST QUARTER OF 2023
Barcelona is the last quarter OF 2023

Update on Rosie and Barc
Updated firmware using app to the most recent .

Had some issues with mngp2 update but thanks to another thread on the forum I got it resolved.


SoC still seems to  be a problem though it's now at stuck at 10% instead of 0%.Will give it some time and see what happens.

I would say that's an improvement 😁😅

Update.

A re-installation of firmware solved SOC readings.
However, Rosie displayed a new behavior last night about 3am.
She decided to shut down for no apparent reason , no fault or warning.
This was confirmed from bedroom mini split shutting making the room hot and from the time reading on the bedroom clock.
I hope she is not ill.
Any thoughts on how to confirm or not she is really ill?I am hoping for a screwup on my side(setting ) rather then she being ill.She has never done this before.

Go to Setup--> Inverter Specific--> Rosie--> Event logs and give us a list of the events leading up to the outage

[mahendra]

Will do.

Log and fault screen

[mahendra]

more not allowed to add in one message

[mahendra]

The only date and time log found

[mahendra]

The only suspect I found  that seems related (happened the same day today) was a blown rack and pinion DC gate motor powered by 120vac adaptor that's built in. Gate was temporarily inoperable until fuse was changed.

Additionally, a few days ago I got a ground fault notification on Barcelona. (Ground fault toroid was installed and activated; Arc fault was not installed because of missing plug on options board but new board is on its way).
After it was cleared it went away. There was no disruption in power generation from Barcelona or Rosie during this notification.

I am officially puzzled as; I was expecting something else from the logs and faults screens.

[FNG]

I do wonder if the Gate motor created a short on one leg that caused it to reset due to overload. I would expect an AC overload error but if it was quick enough the Rosie may overload into what we call a DESAT and if so it will reboot to protect itself without a log entry as it is primarily concerned on preservation not logs. Has it done it again?

All the numbers I see look like a couple aborted firmware updates and a lack of factory firmware, neither of those have any effect on operation
