SMA's Sunny Central String Monitor continuously measures the DC currents of the individual system strings and transmits them to the inverter monitoring system. Comparing individual string currents enables accurate detection and analysis of power deviations in the solar array.

Sunny Central string monitor also relays any error messages to the Sunny Central String Monitor Controller (SCSMC). The operator can then access the data through the inverter monitoring system.

String Monitors are available in three sizes for connection of 24, 32, or 64 strings in a PV system. The Sunny Central String monitor is contained in a NEMA 3R steel (or optional stainless steel) enclosure suitable for wall or pole mounting.

Detachable side and base plates provide for convenient installation. The String Monitor is rated for arrays with a maximum 600 VDC and can be configured for negative or positive ground systems. Ideal solar PV grid tie inverter.

Grid-tie solar PV string Sunny Central String Monitor Controller connects up to 9 String Monitor combiners via RS-485 hubs to a Sunny WebBox (typically integrated with the inverter). Multiple String-Monitor Combiners can be "daisy chained" together and connected to a single hub. Up to 4 communication busses can be connected via four RS-485 hubs, enabling connections from four directions.

Sunny Central String Monitor comes with communication range of up to 3,900 ft is possible per hub with data cable (two twisted pair, shielded cable, AWG 24). One Sunny Central String-Monitor Controller is needed per system.
