Hey there, is it possible to connect 2 mppt chargers ( from 2 different arrays) without any kind of connection between chargers? Lets suppose 2 same 75/15 chargers with stock settings, connected in parallel to the same battery. Cheers

Simple connection of 2 mppt chargers
You can have many independent charging sources connected to one battery.
No communication between the chargers is necessary in smaller systems.
Thank u for ur quick reply, what do you mean smaller systems though? Up to 500w? I am talking about a 200w 24v array connected to one charger and another 275w 24v single panel connected to another 75/15 charger, both charging a 230amp battery
Independant systems aren’t no problem until they are together charging your system at more that your battery can safety take (often 2c)
After that you need to thing about DVCC or other means of charge current control.
