Zusammenfassung:	The present disclosure provides a photovoltaic solar inverter with an AC grid filter without inductance connectable to the AC grid. The inverter comprises: a power module for converting a DC input voltage into a three-phase AC output voltage; a three-phase AC/AC transformer for adapting the three-phase AC output voltage of the power module to the three-phase AC voltage of the AC grid, which has an inductance "L2". The three-phase AC/AC transformer comprises a winding on the grid side with an equivalent inductance "L1"; a capacitor "C", connected to the winding of the grid side of the three-phase AC/AC transformer. The equivalent inductance "L1" of the AC/AC transformer, the capacitor "C" and the inductance "L2" of the AC grid form a high frequency "LCL" filter, eliminating the inductances provided only for forming the LCL filter. The disclosure also provides an AC grid filter without inductance with an "LLCL" typology.
