As introduced in Chap. 1, the photovoltaic (PV) inverters are the key link responsible for converting solar energy into electricity. The topology and control technology directly determine the investment costs, conversion efficiency, and output performance of the PV generation system. There are many topologies for connecting PV modules to the grid.
As solar technology improves, panels often produce higher voltages, so it's important to select an inverter that can handle these surges, especially during periods of peak sunlight. Typically, residential inverters have a maximum input voltage between 500V and 1000V.
Higher voltages also enable the design of higher-powered PV inverters. Although some components such as insulated gate bipolar transistor (IGBTs), diodes, and fuses necessary for higher voltages may come at a higher cost, a higher voltage PV system and higher power density can offer lower overall costs on a dollar-per-watt basis.
This article introduces the architecture and types of inverters used in photovoltaic applications. Inverters used in photovoltaic applications are historically divided into two main categories: Standalone inverters are for the applications where the PV plant is not connected to the main energy distribution network.
For grid-tied systems, this is typically 220V or 230V in most countries. For off-grid systems, it might be 48V or 24V, depending on your battery configuration. Ensuring this rating matches your power system's output guarantees that your inverter will efficiently convert energy without risk of damage.
Most inverters now come with multiple battery voltage options, allowing for greater flexibility in system design. Understanding the voltage ratings of your inverter ensures safe, efficient, and reliable solar energy production.
