Hi, I just updated my Barcelona to the latest release.
2 things I have noticed:
1. The system status is reading "Battery 54.2V. -3093A"
The A is actually the watts I think?
2. Barcelona's output seems to be seriously reduced. The battery is at 80%, we are still BULK charging and yet I am seeing about a 6th of the output from the panels than I should be seeing.
Any ideas?
Jim
and, another thing to note:
my display is reading:
Battery 54.5V 3173.1
MPPT 1 MPPT 2
344.0V 450.6V
58.1A 0.0A
3167W 0W
0.9 kWh 0.1 kWh
Bulk. Resting
Why resting?
Thanks again,
Jim
And with the MNGP2 on the Inverter page, I have probably 4000W of devices on and it's showing an output 929W
I updated the MNGP2, Barcelona and Rosie all yesterday evening Jan 31 2026

Scrap this, a breaker had tripped.
You should probably also do a factory reset for both the mngp2 and the barcelona in case you havent done that. Some updates need to start fresh for the new features to work properly.

Thanks for the post Larry,
I've factory reset both Rosie and the Barcelona, how do I factory reset the mngp2? I can't find a manual for it.
Thanks for the help, much appreciated..
Jim
I don't have it in front of me now but I think I remember there is a separate reset for mngp2 somewhere in the mngp2 menus.
Larry
The factory reset worked for the barcelona and rosie.
Problem solved thank you.
