The Fronius Smart Meter CT V 100A/333mV is a clip-on current transformer (split-core) for precise current measurement in larger photovoltaic systems. It is simply placed around the conductor – without cutting the cables – and converts the measured current into a 333 mV signal, which is evaluated by the Fronius Smart Meter (WR 100-600V-3 or IP).

With a primary current of 100 A and accuracy class 1, it enables reliable measurement of grid consumption and feed-in, even at higher currents. The CT V 100A/333mV is the ideal complement to Fronius Smart Meters for precisely optimizing self-consumption, storage control, and surplus charging.
