Three Phase Grid Tie Inverter

BW8K/10K/15K/17K/20K-LT-G2 | 8-20KW |Three Phase | 2 MPPT | String Inverter

Our 8-20K LT-G2 series three-phase inverter developed for the benchmark of the large-scale commercial, industry, and residential decentralized PV system, which demands high performance, quick installation, easy commissioning, less maintenance, and durable reliability. A wide MPP voltage range with 150% oversizing of the PV array ensures optimal energy yield and applicable flexibility in nearly every situation. With a rated 13A input current per string, it’s ideal for bifacial and large area PV modules. Compact wall mounting with IP66 rated design concrete sustainable usability against most environmental impacts. With a smart cloud-based monitoring app, it’s practical to keep tracking your PV inverter system wherever you are.
