How to select a solar inverter ?

Updated: Jan 4, 2023


# What is a Solar Inverter ?


A solar inverter is a device that converts the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity, which can then be used to power homes and businesses. The inverter is an important component of a photovoltaic (PV) system, as it allows the solar panels to interface with the electrical grid and other loads.


There are several types of solar inverters, including string inverters, microinverters, and central inverters. String inverters are the most common and are used in systems with a single string of solar panels. Microinverters are attached to each individual panel and can improve the performance of a PV system by allowing each panel to operate independently. Central inverters are used in large-scale PV systems and can handle the output of multiple strings of solar panels.


Solar inverters are typically rated by their power output, which is measured in watts (W). The size of the inverter needed for a PV system depends on the size of the solar panels and the total electrical load of the home or business. Inverters also have a maximum efficiency rating, which indicates the amount of the DC power produced by the solar panels that is converted into AC power.


# What are the types of Solar Inverter ?

There are several types of solar inverters that are commonly used in photovoltaic (PV) systems:

  1. String inverters: These are the most common type of solar inverters and are used in most residential PV systems. They are called "string" inverters because they are connected to a string of solar panels. String inverters convert the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity that can be used in a home or business.

  2. Central inverters: These inverters are used in large, utility-scale PV systems and are typically located at a central location within the PV array. They are designed to handle the high power outputs of many solar panels and are usually more efficient than string inverters.

  3. Microinverters: These inverters are attached to each individual solar panel and convert the DC electricity produced by the panel into AC electricity. They are a good option for PV systems with shading issues or for those that want to maximize their energy production.

  4. Battery inverters: These inverters are used in PV systems with energy storage, such as in a home with a solar battery. They are designed to charge the battery with electricity produced by the solar panels and to discharge the battery as needed to power the home.

  5. Hybrid inverters: These inverters are a combination of a string inverter and a battery inverter, allowing them to both produce electricity from solar panels and store excess electricity in a battery for use later.

# How to select a solar inverter ?

There are several factors to consider when selecting a solar inverter:

  1. Type: There are three main types of solar inverters: string inverters, microinverters, and central inverters. String inverters are the most common and work with a single string of solar panels. Microinverters are attached to each individual panel and can improve system performance, but they are also more expensive. Central inverters are used in large commercial solar systems.

  2. Size: The size of the inverter should match the size of your solar panel array. An inverter that is too small will not be able to handle the power output of your panels, while an inverter that is too large will be more expensive and may not be necessary.

  3. Efficiency: Look for an inverter with a high efficiency rating, as this will allow your system to convert more of the solar energy into usable electricity.

  4. Features: Some inverters come with additional features such as monitoring and management systems, built-in battery backup, and the ability to connect to a home automation system. Decide which features are important to you and select an inverter that offers them.

  5. Warranty: Make sure to consider the warranty offered by the manufacturer. A longer warranty period can provide peace of mind and may save you money in the long run.
