Hi,
I have just updated my MPPT BlueSolar 150/60 to the latest firmware v1.39.
The next day what I noticed is that there was no absorption cycle. Instead the MPPT went straight into Float mode.
Also I noticed that after the upgrade the MAX battery voltage was only 53.96v - it has always been around 58v (which is the manual configuration I have in the MPPT settings)
Is this normal behaviour?
Has anyone else go the same issue perhaps?
I have a 48v battery bank (4x 12v AGM 300A batteris in series) with 36 solar panels PV and a Victron MultiPlus inverter.
thanks
