Hi. Often enough I've encountered members saying it's generally okay to use two MPPTs on one bank.
I've not found clarity on the question I have in mind though.
The scenario is:
- same battery bank
- first charge controller is programmable MPPT
- second charge controller is UNprogrammable mppt
I guess ideally I'd set the programmable unit to match the settings of the unprogrammable unit.
But what if the batteries have specific setting preferences - like one Trojan range lists bulk 14.8 and absorb 13.5 for 12V system.
The unprogrammable unit bulks (it's LED is labelled 'boost') at 14.8, but absorbs (it's LED is labelled 'float') at default 13.8.
So - change programmable settings to match the ideal battery specs, or to match the unprogrammable unit settings?
Considering that Sunking frequently says that there is no setting high enough for us off-gridders, I'm hoping the latter is acceptable.
