Operating at close to minimum of inverter MPPT range
I am looking at putting some panels on my existing Ecco 5k + battery only setup. However it would seem I could only fit 5 panels on each of 2 roof areas. One area is in shade in the morning so I am looking at putting 5 panels on each MPPT input of the inverter.,
However, I see the typical 450W panels have a Vmp of 32.9v (STC) , 30.7 (NOCT). The inverter spec asks for a minimum of 150v. 5 panels would provide 153v @ NOCT.
My concern is that at either end of the day, or in winter months I may not hit the 150v minimum. Will the inverter still function and just do it's best or would the MPPTs shut off?

I assume it is the surface temperature of the panel, not the ambient used for these calculations. Difficult to guess.
