Guard access issue is fixed now? this was an issue only if you successively part arm the system 4 times, which to be fair during the pandemic has been more common.
The low battery device issue is being looked at and whilst this isn't an issue under regular maintenance ie 2 year battery replacements it is a concern that your likely to get a supervision fault first rather than a battery failure. Not sure what the true cause is behind this yet as some folk are still getting low battery warnings normally from what I have read (I see very few of these issues with my customers but have seen it on my test systems, the difference is my customers batteries get replaced before they fail usually), although I think it could be related to the way they now calculate the low battery condition.
The load test was a fudge as far as I am concerned for grade 2 panels and far better replacing the PSU to the -6.They did indeed get the first fudge wrong before it was corrected but not into fudging.
As for the capture, no idea what is happening there, not had an issue with locking any of them. even with 2 x 8 core cables in when testing recently and one 8 core running past the locking mechanism.
Riddled I would say no, issues yes.
