SMA MC-PB Piggyback Communications Card
SMA, Multicluster Communications (Piggy-Back) Card, One for each SI Cluster Master, MC-PB
The Sunny Island inverters can be retrofitted with the SMA MC-PB multicluster piggyback board for communications with the multicluster box. This card allows communication between the main cluster and extension clusters through a controller area network (CAN) and RS485 protocol. The Sunny Island inverters can also communicate with other SMA inverters and communications devices thanks to this feature. The SI4545-US-10, SI5048-US, and SI6048-US-10 are all compatible with the MC-PB.
