SUNNY CENTRAL STRING-MONITOR-US

SUNNY CENTRAL STRING-MONITOR-US

Insurance for solar yields in North America

Sunny Central String-Monitor-US provides detailed PV array monitoring for the North American market. By measuring and comparing individual string currents, power deviations in the solar array are accurately detected and are analyzed in the Sunny Central inverter. The Sunny Central String-Monitor-US is delivered in a NEMA 3R enclosure for wall or pole mounting, according to preference. For the string current measurement, there are three variants of string fuse protection, all of which comply with the NEC standard, making the Sunny Central String-Monitor-US ideally suited for use in North America.
