Yeah that's a different issue.If I set mppt to 28 it still goes up to 30V
If you can set it so it doesn't exceed 28 then you can get by until solving the issue.

Because bulk and absorption aren't the same thing at all.Another question, Bulk and Absorption are considered the same. But why does this MPPT have 3 separate lamps then? One for bulk, absorption and float. When at bulk, most of the time voltage seem to be correct. Then when alarms comes, it generally did most of the charging needed. Could it be that it is a high voltage due to battery being full and that I at that time don't get any amps anyway? I guess high voltage with low amp still can overcharge battery

Yours may be set to the same voltage, but they have different functions.
That would be odd if so.Hmm...maybe I should break the connection between these victron units. Maybe it is a combination of that Victron Inverter and Victron SmartShunt informs the VIctron MPPT about loads, hence the MPPT adjusts abnormally. Will try to break the the internal network for the to see if any changes
Not able to. I cannot get BT connection with MPPT as it says connected to other device. Tried logging out of VRM and also disconnecting my Raspberry PI that is connected via USB to all my three Victron devices. Seem that a reset of the MPPT is needed.That would be odd if so.
But I'd like to know as I'm using a 75/15 and a smartshunt myself
With Victron chargers you can set the following values that determine the charge process.If I cannot set bulk voltage anywhere I guess me changing settings for absoptiondoes not matter.
I removed the positive Shunt cable to battery. No new alarms yet. Output towards battery is a bit higher than the mppt tells me but nowhere near 30 v.I have not disconnected the pos cable yet but I accessed the shunt and disabled the ve network. Currently mppt volage towards battery is 29,4 v
