    Appendix ystem description ABB grid-tied inverters provide the capability to supply the utility grid with energy obtained from photovoltaic panels. To use the DC generated by a photovoltaic field efficiently, it must be transformed into alternating current (AC) via a conversion process known as DC-AC inversion.

  • Page 68: Protective Devices Within The Inverter

    These versions of ABB inverters utilize “high-frequency switching” transformers, to provide a high-level of gal- vanic isolation between inverter input (array) and output (grid). This circuitry provides galvanic isolation from the secondary (AC side), while maintaining very high performance in terms of energy yield and export.
