What is a photovoltaic inverter?The main purpose of the inverter is to transform the voltage and current waveform generated by the photovoltaic modules from continuous to alternating, adapting the PV generator output characteristics to the standards of the local network.
How does a photovoltaic inverter work?The inverter must dissipate the minimum amount of power, avoiding losses and producing a voltage with low harmonics and in synchrony with the grid (on-grid system). These inverters are equipped with the Maximum Power Point Tracking (MPPT) function capable of obtaining the maximum possible power from the photovoltaic modules.
How to dimension a photovoltaic system?The dimensioning process of a photovoltaic system connected to the grid is based on the choice and suitability of the module and DC/AC inverter and other peripheral equipment. The inverter sizing factor is the relationship between the inverter power and the PV generator power, and your choice depends on several factors.
What is the ratio between inverter power and rated power?Thus, in this project, we opted for the configuration with a central inverter (modules connected to it) with a nominal power of 40 kW and, consequently, the ratio between the nominal power of the inverter and the rated power of the PV generator is 0.83.
