Both Solaredge and Enphase have problems with Sunpower and BenQ panels voltage.
If space is a premium has the installer tried Pansonic Hybrids. I think they are compatible and are continually fighting with Sunpower over which is the best panel.
If space is not an issue, then for my money the ROI with a good quality REC, Hyundai or LG panel is better.
Hope this helps.
