Grid-connected multilevel inverter for solar PV application . An MLI is selected for medium- and high-power applications based on its capability to generate voltage waveforms of superior quality while functioning at a low switching frequency [104, 105, 106, 107, 108].
HERIC = highly efficient and reliable inverter concept; MLI = multilevel inverter; MPPT = maximum power point tracking; NPC = neutral point clamped; PV = photovoltaic; QZSI = Quasi-Z-source inverter; THD = total harmonic distortion. This comprehensive table presents recent developments in grid-connected inverter topologies (2020–2025). 4.
Beginning with an introduction to the fundamentals of grid-connected inverters, the paper elucidates the impact of unbalanced grid voltages on their performance. Various control strategies, including voltage and current control methods, are examined in detail, highlighting their strengths and limitations in mitigating the effects of grid imbalance.
4. Grid-connected inverter control techniques Although the main function of the grid-connected inverter (GCI) in a PV system is to ensure an efficient DC-AC energy conversion, it must also allow other functions useful to limit the effects of the unpredictable and stochastic nature of the PV source.

The representative residential PV system (RPV) for 2024 has a rating of 8 kW dc (the sum of the system's module ratings). Each module has an area (with frame) of 1.9 m 2 and a rated power of 400 watts, corresponding to an efficiency of 21.1%.
We chose a 100-MWdc PV system because that was the approximate average size of U.S. utility-scale systems reported in EIA (2022). The per-unit cost results are meant to be generally applicable to systems with PV sizes between about 50 and 200 MWdc.
