I currently have the 360w and two 200w in series with a fuse to a Growatt 24V SPF 3000TL LVM, 80A MPPT 2KW PV, PV Input 30-115Vdc, PV Max input 145Vdc.
I think I can add the two 400w in series with a separate fuse in parallel with the existing string.
I would like a sanity check before I risk the hook up.
Any risks other than the power loss due to the different PMAX voltages 81.52 vs 83.4?
