The selection of IGBTs depends on the inverter's switching frequency: 2–10 kHz: Industrial motor drives, traction systems. 10–20 kHz: Solar and wind power inverters. 20–100 kHz: High-frequency power supplies. [pdf]
This article provides general information about IGBT power semiconductors and, in particular, provides explanations about component parameters and graphs in Bourns’ IGBT data sheets available at Information about power MOSFET and bipolar transistors is also included for comparison. [pdf]
The rule of thumb is to size your inverter 1.25 bigger than your solar array. In some cases, you may need to use multiple inverters to meet your power needs or increase your system’s voltage. This practice, known as inverter stacking, involves connecting multiple inverters in parallel or series. [pdf]
