I used my MPPT on a 24v battery system. Now I changed the battery system to 48v.
The user manual shows that the system voltage can be changed via the app - and I found it there in the settings.
My question is:
Do I need to change the voltage setting from 24v to 48v while the MPPT is connected to the 24v battery - because it's current setting is 24v?
Or can I connect it to 48v and then change the system voltage from 24v to 48v?
This is not clear documented and I do not want to destroy it.
I also already searched this forum without success.
