System overview
Solar Generation for Grid-Connected Buildings
Choose BSM15K-B, BSM17K-B, BSM20K-B or BSM25K-B to match the required AC output. PV generation connects through the string inverter to the site electrical system and utility grid.
This series has no battery connection. Solar module selection, array size, mounting and electrical accessories are configured for the project.
Dual MPPT
Two independent MPPT trackers.
Outdoor Inverter
IP66 enclosure protection for the inverter.
Monitoring Options
RS485 communication; optional Wi-Fi / 4G.
