Generac APKEPM820 PM-820, 820W Dual Input Micro Inverter

Generac PWRmicro PM-820 Dual-Input 820W Microinverter

The Generac PWRmicro PM-820 (APKEPM820) is a high-efficiency 820W dual-input microinverter engineered for residential photovoltaic installations. Utilizing a 2:1 dual-module architecture, this microinverter connects directly to two high-powered PV modules up to 500W each, effectively halving the total number of microinverters required per array.

Equipped with dual independent Maximum Power Point Tracking (MPPT) channels, the unit maximizes total energy harvest across varied shading and roof orientations with 97% CEC efficiency. Built to withstand extreme environmental temperature and humidity conditions, the PM-820 features Field Pro nighttime commissioning and instant device discovery, backed by a 25-year manufacturer warranty with 5-year labor coverage.
