SMA Sunny Central String-Monitor Provides Insurance For Energy Yields
Sunny Central String-Monitor-US offers optimal fault detection of large-scale PV arrays for the greatest return on investment.
- (1888PressRelease) December 16, 2010 - ROCKLIN, Calif. - Large-scale PV system owners can now protect their investments with SMA America's Sunny Central String-Monitor-US, which instantly and accurately detects power deviations by measuring and comparing individual string currents. These interruptions can then be corrected by system owners immediately, reducing the duration of suboptimal system performance and maintaining maximum energy yields for the greatest return on investment.
Performance disturbances can go unnoticed in a PV system without string monitors, leading to decreased energy yields and loss of revenue for extended periods of time. However, the Sunny Central String-Monitor-US continuously monitors the strings and transmits fault data to the SMA Sunny WebBox. The SMA Sunny Portal then sends an email alert to the system owner for immediate attention.
"Timely and accurate system monitoring is essential to maintaining peak power production," said Jurgen Krehnke, president and general manager of SMA America. "The Sunny Central String-Monitor-US ensures early detection of performance changes to help secure the highest possible energy harvest from large-scale PV systems."
SMA's versatile monitoring solution is available in three models: the Sunny Central String-Monitor-US 24, 32 and 64. The model numbers indicate the total number of strings each unit monitors. Sunny Central String-Monitor-US devices can be combined in multiple configurations based on the number of strings in the array, providing the best possible system design. Up to nine Sunny Central String-Monitor-US units can be connected to a single SMA Sunny Central inverter.
The outdoor-rated Sunny Central String-Monitor-US has a NEMA 3R enclosure and can be ordered with an option for use in aggressive environments. It boasts detachable side and base plates for convenient installation preparation and can be wall or pole mounted, according to preference.
The Sunny Central String-Monitor-US is UL Listed and meets NEC standards, making it ideally suited for use in North America.
