MPPT not getting into absorb, only bulk

bulk-then-drop.pngscreenshot-20240521-105312.pngI have a MPPT 75/15 connecting a 110Ah Leisure Plus battery and 160W panel.

All was working well, until the last week, whereby I seem to get a short period of bulk charge, which then cuts out and drops to charger off - where I would normally see abs/float.

Any ideas why this might be? I don't think I have changed any settings, the wiring appears ok.

@Oli Clarke There is a firmware update available.

Download Victron Connect 6.10beta4 and apply mppt firmware v1.64.

@Oli Clarke if that fails, Check your solar panels.

I don't seem to be able to get the APK to install - I'm on a Pixel 6, so the ARM format should work. I enabled allow unknown source, so strange.


Is there an alternative way to get the firmware onto the controller?
