Frage 12v or 24v system?

Hello,

We have a Columbus 601d.

i recently changed the leisure batteries like for like. The original westfalia control panel reads the usual voltage 12.8, 13 etc but the Victron solar charger is set to 24v and shows a half full battery?

is the system definitely 12v not 24v? Should I change the victron solar controller?

if it’s 12v but solar thinks it’s 24v surely it will overcharge and cause damage!

thank you.

correct. The solar charger setting us wrong. Should be set to 12 V
