Connecting an MBUS Cable

Connecting an MBUS Cable


If both the SmartLogger and the solar inverter support MBUS, the SmartLogger can be connected to the solar inverter through an AC power cable. In this case, you do not need to connect the RS485 communications cable to the solar inverter.

If the SmartLogger uses an AC power cable as the communications cable, an MCB and a knife fuse switch need to be installed to prevent device damage in the case of short circuits.

The rated power of the PV system connected to the MBUS port on the SmartLogger must be greater than 75 kW.
