What is a string inverter?
A string inverter is a device used in photovoltaic (PV) solar energy systems to convert direct current (DC) electricity generated by a series or “string” of solar panels into alternating current (AC) electricity. This type of inverter is typically installed centrally in a solar panel setup, where it manages the combined DC output of multiple solar panels connected in series.
String inverters are widely used due to their cost effectiveness and simplicity of design, making them suitable for small residential and commercial solar installations.
What is a string inverter?
An inverter is an electronic device that converts direct current (DC) into alternating current (AC). This conversion is crucial because most household appliances, electrical networks and electronic devices run on alternating current. Inverters are essential in a variety of applications, including solar power systems, uninterruptible power supplies (UPS), and backup generators.
They ensure that energy generated or stored as DC can be used by AC-powered devices and systems, while maintaining compatibility with standard electrical infrastructure.
What is an inverter and what does it do?
There are several types of inverters, each designed for specific applications and electrical needs.
The main types include:
String Inverters: Used in residential and small commercial solar systems, these inverters convert DC power from a series of solar panels into AC power.
Microinverters: Installed on each solar panel, these inverters convert direct current to alternating current at the panel level, allowing for improved performance and monitoring.
Hybrid inverters: combine the functionality of on-grid and off-grid inverters, managing both battery storage and grid connection.
Off-grid inverters: Designed for systems not connected to the utility grid, converting DC power from batteries or solar panels to AC power for stand-alone use.
Central inverters: Used in large-scale solar installations, they manage the output of multiple panels and convert it to AC power for distribution.
An inverter card, also called an inverter module or inverter card, is a component of an inverter system that manages the conversion of direct current to alternating current.
It typically contains the electronic circuits and components responsible for the conversion process, including transistors, capacitors, and other semiconductor devices. Inverter boards are crucial to the operation of inverters, providing the functions necessary to transform electrical energy and efficiently manage its production.
