Detailed string cluster monitoring: the Sunny Central String-Monitor US. By measuring and comparing individual string currents, power deviations in the solar array are reliably detected and analyzed in the Sunny Central. The Sunny Central String-Monitor US is available in three models, each with varying NEC compliant string fuse protection, making the Sunny Central String-Monitor US well suited for all panel types in the North American solar market.

Product is housed in Nema 3R protection rated casing and can come in steel or aluminum. The Sunny Central String-Monitor sends data via an RS485 data link. From there, the data can be transferred to a PC for further processing or to the Sunny Portal for automatic performance analysis.
