A solar inverter, also known as a photovoltaic (PV) inverter or solar energy converter, is an essential component of a solar power system. Its primary function is to convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is the standard form of electricity used in most homes and businesses.
Solar inverters can be classified into different types based on their technology and application:
String inverters: These are the most common type of solar inverters used in residential and small-scale commercial installations. They connect multiple solar panels in a series, creating a "string" of panels that feed power into a single inverter. String inverters are typically more affordable but have some limitations when it comes to shading or panel mismatch.
Microinverters: Microinverters are installed on each solar panel in a PV system, allowing each panel to convert DC to AC electricity independently. This can improve system performance in cases where panels are shaded or face different orientations. Microinverters also make it easier to expand the system in the future.
Power optimizers: These are a hybrid between string inverters and microinverters. Power optimizers are installed on each solar panel, maximizing the output of individual panels by performing maximum power point tracking (MPPT). The optimizers then send the DC power to a central inverter for conversion to AC.
Central inverters: These are large-scale inverters used in commercial and utility-scale solar installations. Central inverters are designed to handle high amounts of power and can support hundreds of solar panels in large solar farms.
Battery-based inverters: These inverters are used in solar systems with energy storage, such as battery banks. Battery-based inverters not only convert the solar-generated DC power to AC but also manage the charging and discharging of the battery system.
