With the use of central inverters it is very important to combine the available DC-strings to the few collective DC-conductors. Our iAT decouples, processes and records all information regarding the states of the DC-fuses and DC-currents. The iAT is normally installed close to the central inverters where the information processed by the iAT is provided to the iMT.
