4.1.4 Connecting an MBUS Cable
Context
● 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.
NO TICE
The rated power of the PV system connected to the MBUS port on the
SmartLogger must be greater than 75 kW.
