What are the types of solar inverters?

Solar inverters come in several types, each designed for specific applications and system configurations. The main types of solar inverters include:

  • String Inverters: String inverters are the most common type of solar inverters used in residential and commercial solar energy systems. They are typically installed in a central location and connected to multiple solar panels arranged in strings. String inverters convert the DC electricity generated by the solar panels into AC electricity and are known for their simplicity, reliability, and cost-effectiveness.

  • Microinverters: Microinverters are small inverters installed directly behind each solar panel in a solar energy system. Unlike string inverters, which handle the conversion of DC to AC electricity for multiple panels, microinverters operate independently, converting the DC electricity from each panel into AC electricity. Microinverters offer advantages such as individual panel-level monitoring, improved shading tolerance, and increased system efficiency.

  • Power Optimizers: Power optimizers are devices installed at the back of each solar panel in a solar energy system, similar to microinverters. However, instead of converting DC to AC electricity, power optimizers optimize the DC electricity output from each panel before it is sent to a central string inverter for conversion to AC electricity. Power optimizers can improve energy production, mitigate shading issues, and enhance system performance, especially in installations with partial shading or uneven panel orientation.

  • Hybrid Inverters: Hybrid inverters, also known as battery inverters or multi-mode inverters, are designed for use in solar-plus-storage systems that incorporate battery storage. Hybrid inverters can manage both the DC electricity generated by solar panels and the DC electricity stored in batteries, converting it into AC electricity for use in the building or export to the grid. Hybrid inverters offer features such as backup power capabilities, grid independence, and energy management functionalities.

  • Grid-Tie Inverters: Grid-tie inverters, also known as grid-interactive or grid-connected inverters, are designed to integrate solar energy systems with the existing electrical grid seamlessly. They convert the DC electricity solar panels generate into AC electricity synchronized with the grid’s voltage and frequency. Grid-tie inverters allow excess electricity generated by the solar panels to be exported to the grid, reducing reliance on grid-supplied electricity and potentially earning credits or compensation through net metering programs.
