Mind4Energy’s PV monitoring can include detailed measurements on the AC side of the PV plant. To accomplish this, a power analyzer is connected to the AC side. A power analyzer allows a detailed analysis of the AC side of the system (voltages, currents, frequency, power factor, harmonics…). This is particularly useful in case of an unstable public grid or if there are local effects on the grid (for instance high harmonics or sudden voltage drops,…). The variables measured by the power analyzer (such as active and reactive power, power factor) are used in Mind4Energy’s demand control system.
