String Box Monitor, Feature : DC Monitoring Of PV Strings.

SBM-16 The String Box Monitor is designed to monitor DC current of Solar PV strings using non-contact Hall Effect Sensors or DC shunt Resistors. Solar panels generate DC current, which flows through strings into a combiner box. String monitoring box SBM-16 measures the current flowing through individual strings in the combiner box to check that the solar array is operating at its peak capacity, before they are combined into one DC output. Using this technology one can detect instantaneously any issues affecting the photovoltaic array and therefore the energy yield by the PV modules.
