ASW 3-20K LT-G2 Pro Series

Versatile benchmark, innovative high-yield inverter

ASW 3-20K LT-G2 Pro series, upgraded innovative development for the benchmark of residential, large-scale commercial, industry decentralized PV system. Along with the innovation of larger size wafer-based PV modules, ASW 3-20K LT-G2 Pro series three-phase inverters are perfectly compatible with those high-power PV modules.

2 independent MPP trackers and up to 32A rated input current per MPPT, make it possible to collocating PV plant with more applicable choice of bifacial large area PV modules. A wide MPPT range with 150% oversizing of PV array ensures high energy yield and more flexibility in nearly every situation.

Compact wall mounting with IP66 rated design concretes sustainable usability against most environmental impacts. With a smart cloud-based monitoring app, it’s practical to keep tracking your PV system wherever you are.
