Good and sunny day to everyone,
I just upgraded my mppt charger via VRM Remote Firmware Update feature from v1.46 to v1.47 as usual and despite upgrade went as expected and successful (saw 1.47 as new firmware on dashboard), somehow the console PV Charger indicator started to show fluctuations between ~1400 watt and 0 (zero watt) in every 2-3 seconds in a loop.... 0-5x-8xx-14xx-0-5x-7xx-14xx....watt. something like MPPT is rebooting in a loop.
I thought that it may be the online upgrade which created this problem, and for a second time, I downloaded "Solar Charge Controller MPPT 150-100 rev2 SMART v1.47_A059.dup" file from Victron web and once again upgraded from VRM portal, this time by providing custom firmware file. it again upgraded successfully but did not solved the issue.
I had to return back to original firmware "Solar Charge Controller MPPT 150-100 rev2 SMART v1.46_A059.dup".... and now everything is stable like before....
12:48 - online upgrade to v1.47 from v1.46
12:58 - online upgrade with manual upload of dup file v1.47 to v1.47
13:21 - downgrade to v1.46
So anyone else faced similar issue before? I checked the firmware release notes and did not see any special instructions for v1.47. Also I did not see anything abnormal in the logs, no alert of warnings. Anyone knows where is the upgrade and mppt logs files and how to see them so that I can debug the issue?
Thx...
