Hello,
Since the update at the beginning of April of the Android application of Victronconnect which updated the firmware of my 2 Victron regulators (v1.5), I notice erratic behavior, although I have the latest version 2.25 to date.
Presentation of the installation:
- I have 2 panels of 130W in 12V in parallel on my roof coupled to a 100/30.
- 1 panel of 100W 12V "mobil" with a 75/15 regulator
- 2 batteries of 90Ah in 12V connected in parallel on which the 2 regulators are connected in parallel.
In February following the installation of the 75/15 and the mobile 100W, my whole installation worked perfectly, the roof panels and the mobile worked together, with peaks at 100W on the mobil (perfect orientation in the sun), and surroundings 150W on the roof (because in winter and flat).
The 100W panel and the 75/15 being sometimes sufficient in floating, the "victron connect" network cut "(0W) even the 100/30 regulator and only turned it on when I was using my water pump, or my computer, because power demand greater than 100W. So, everything it's normal way.
Since the April update, the roof panels can go up to 260W currently but the 100W mobile never exceeds 25W / 30W approximately, whether my 100/30 regulator is activated or not (simulating the fact that I am totally at shade) and those even with batteries at 12.4V in the early morning.
I obviously checked the material before coming to you:
- Changed regulator (SAV) thinking that the problem came from him (new for 2 weeks)
- Changed connectors and cables
- Tested with other solar panels (100W in 12V, in 36V, 200W in 24V etc ...)
No significant change, all panels remain flanged within 30W on the 75/15 regulator.
I also went to see a motorhome dealer who did not understand either, the panels having been tested and all in function according to the labels on their back.
This is why I came to the conclusion that there is a firmware problem.
Would it be possible to send me the firmware in effect at the end of January that I downgrade those of my regulators (from the tab: "firmware library") because all my installation which worked perfectly, and has been verified by a professional, and which has not changed since the update in early April (v5.20 (Released officially) from 2020-04-06) which caused this erratism behavior.
In addition, we meet another German family with substantially the same installation has exactly the same problems as me with a mobile panel of 100W in 36V never exceeding 35W with the roof panels in the shade.
Attached:
- screen of the 2 Victronconnects with erratic behaviors (100/30 ON and 75/15 OFF, 100/30 OFF and 75/15 ON, 100/30 ON and 75/15 ON),
- screen of the 2 regulators with serial number to have the old versions of the corresponding firmware.
thank you,
Florent
