@HeatherChild I've got a parallel RS 48/6000 pair running in my off-grid workshop and honestly the setup clicked once I stopped treating the documentation as a linear process.
Great points from everyone so far. To finish what @DevonDweller was likely getting at and pick up my own thread — synchronisation events are everything with coulomb counting shunts.
Great points from @Sam1965 and @TimKnight already. One thing worth adding — once you've sorted your cold-weather Voc headroom, don't forget the charge current side too.

@RachelLamb to add something slightly different to what the others have said — worth double-checking what your MPPT charge controller is set to output.
Great thread @EmmaPowell74. One thing worth adding that nobody's mentioned yet — have you checked whether your shunt monitor is actually temperature-compensating its readings?
