1 … A device represents an inverter, stringbox, MPP tracker, battery monitor, meter or any other device which can be detected on any serial bus or via ethernet communication.

2 … Can be configured by software (web UI, XML).

3 … Piggy-back functionality replaces the “2x RS485 or 1x RS422” interface.

4 … SM2-BE is mutually exclusive to the SM2-GSM usage. 2x SM2-BE modules can be also used to extend the HBUS connection between SM2 modules.

5 … Communication speeds are available according to selected device communication protocols.
