The document discusses two common configurations for grid-connected solar inverters in residential applications. Configuration 1 uses a boost converter to increase the solar panel's DC voltage before passing it to an inverter. The inverter then converts the DC to 230V AC electricity that can be used in the home or fed into the electric grid. Configuration 2 has distributed maximum power point tracking for higher efficiency. Both configurations aim to efficiently convert the variable voltage solar panel output into standardized alternating current.
