converting a 12v system into 24v

hey there, i am planning to change the panel configuration from 12v (parallel connection) into a 24v one so that i can charge my 12v battery efficiently. should i set my victron mppt controller into 24v or this is auto-detected?when "system voltage" is mentioned, are we talking about the panels voltage or the battery?

sorry for the silly question but i am a novice in solar stuff, cheers

If the MPPT controller has been completely disconnected (no battery or solar) for 10 minutes or more, then it will auto detect the next time it is connected to the battery. Always connect the battery first.

"System Voltage" pertains to the battery Voltage.
