I have a MultiPlus-II 48/5000/70-50, 230V with Victron Energy SHU050150050 - SmartShunt 500A/50mV Connected to my 48 battery bank (2x24v 100ah). The battery level isn’t correct, it jumps up and down without reason. I suspect the battery settings. What are the recomended setting for this battery ?

For the Smartshunt

Key ones are in no particular order

  1. Charged voltage 0.4V below absorption voltage. If you are using 56.8V for absorption then 56.4V.
  2. Tail current 4%
  3. Battery capacity 100Ah
  4. Peukert coefficient 1.05
  5. Charged efficiency factor 99%
  6. Discharge floor 10% or 20% depending on how low you plan on taking them. This is only used to calculate the time to go.
  7. There is a setting towards the bottom of the page about what the unit starts at, if you have a choice then set it to retains value, I can not remember the exact wording.

Leave the others as default.
