Advanced Energy® AE 3TL Inverters Overvoltage Fault 600 SERIES The inverter has two DC inputs, DC1 and DC2, each of which is limited to 500 V. A relay (combiner) inside the inverter connects the two arrays, in series, upon activation. This doubles the voltage level inside the inverter. A symmetry controller balances the voltages of the two terminals, positive of DC1 and negative of DC2, so they do not exceed 500 V with respect to ground under any condition.
