6 FAQs about [String inverter for photovoltaic power station]

What is a string solar inverter?

A string solar inverter is a type of inverter that has multiple inputs for connecting strings of PV modules. It is typically used in larger solar PV systems and is sometimes referred to as a multi-string solar inverter.

Can string inverters be used in large-scale PV systems?

When considering large-scale PV systems, a basic distinction is made between two system concepts: those in which string inverters are used and those that favour a central inverter. The following sections look at the broad operational capability of string inverters and consider their application potential in large-scale commercial systems.

What are the different types of PV inverters?

There are three primary tiers of PV inverters: microinverters, string inverters, and central inverters. Since microinverters are not rated for utility-scale voltages, we will largely ignore them in this article. String inverters convert DC power from “strings” of PV modules to AC and are designed to be modular and scalable.

What should you consider when buying a string solar inverter?

As you shop for a string inverter, keep in mind the power rating, efficiency, number of inputs, size, and price. A string solar inverter is a popular option when investing in a PV or solar energy system. Affordable and easy to install and maintain, it provides a great solution for powering your home or business with solar energy.

Should you put a string inverter under a solar module?

String inverters have an advantage over central inverters in that they are both more compact and lighter, so simply putting them underneath the solar modules will provide adequate levels of shading. With every PV system, it is essential to consider the distances between the module array and the main distributor in advance.

Where are string solar inverters prevalent?

String solar inverters are prevalent in residential solar projects, either rooftop or ground-mounted. The global string solar inverter market size is estimated to reach USD 6.02 billion by 2031. Other than America and Europe, the Asia Pacific and LAMEA (Latin America, Middle East and Africa) are also witnessing rapid growth.
