“Controllers don't compete.”
A single stage controller mixed with a multi-stage controller can cause the multi-stage controller to prematurely switch to float mode, effectively cutting out that controllers harvest - Sometimes referred to as “dueling controllers”...For clarity, not a theoretical matter, this how it can happen...

Nope!
Say the multi-stage will drop to 13.6 two hours after reaching 14.6 (typical EP Solar fixed profile). Now start off with your single stage set at 14.6 in parallel.
"Prematurely" is only because it gets to 14.6 sooner with both on the job. It is not premature wrt to battery SOC.
Two hours after the batts reach 14.6, the multi will drop to 13.6 but the single stays at 14.6.
Whether this is good or bad "depends"

Great information from this exchange, thank you all... I'm all ears... or rather, eyes...
