The two inverter efficiency figures measure different things and cannot be set against each other. MPPT efficiency is how closely the inverter follows the panels; maximum efficiency is how much power it converts at its best load.

UTL’s longest-warranty battery is larger than these: the 170 Ah USB 17100 lists 100 months in total, with the split between free replacement and pro-rata not stated.
