Mixing 30kW and 40kW String Inverters on an Uneven Roof: Notes from a 1.58MW C&I Project

This case note explains why a 1.58MW commercial rooftop PV project used a mix of 30kW and 40kW three-phase string inverters on an uneven roof. It covers how independent MPPT trackers reduce mismatch losses across differently shaded roof zones. More: https://gkoisolar.com
