Wechselrichter from SMA SBS3.7-10 (no WiFi) with KW DC and MPPT

SMA SBS3.7-10 (no WiFi) Inverter 3.68 KW 1 Phases 5 Years Product Warranty

SBS3.7-10 (no WiFi) The first multistring battery inverter—always reliably supplied.
With the SUNNY BOY STORAGE multistring battery inverter, for the first time, up to three different high-voltage batteries can be connected to one battery inverter. To connect larger batteries, three DC inputs can also be connected in parallel. The Sunny Boy Storage has integrated emergency power, which can be switched manually. Furthermore, it can even take over the entire electricity supply of the three line conductors via the optional automatic transfer unit. Thanks to proven AC coupling, the Sunny Boy Storage is ideally suited to new and retrofitted systems. The integrated webserver enables fast and easy commissioning, which is also possible via smartphone or laptop. Energy flows in the household are fully transparent thanks to the direct connection to Sunny Portal and Sunny Places.
