The discovery of solar power’s ability to be used as a prominent source of energy has brought about a major revolution in the view of sustainable development across the globe. Solar energy, as the widest source of energy, proves to be the most applicable solution to the energy consumption rise while still dealing with environmental degradation.
The process of conversion of solar power into usable electric energy involves the setup of an entire solar panel system that consists of an assemblage of numerous parts and machinery. The most important part of this setup is the solar inverter. The inverter is the major machinery that is used for the conversion of a variable direct current (DC) output from a photovoltaic rooftop solar panels into the usable frequency of alternating current (AC). This AC can then directly be connected to the electrical grid of the electrical network.
Accounting for the cynosure-type presence of a solar inverter in a solar panel system, it is highly essential to go for the best quality of solar inverters when installing the system. The durability, efficiency, quality, price, maintenance cost and a number of key criteria have been studies for multiple brands and the best have been listed for you here.
Before going through the top listed solar inverters for your solar power system setup, take a walk through the major types of solar inverters that are available.
Types of solar inverters
Off-grid/ standalone inverters
The off-grid or standalone solar inverters work by generating electricity from solar panels and then use it for charging the solar battery through a solar controller. The off-grid solar panel system uses an off-grid inverter and is not at all connected to the power grid. The standalone inverters work on the electricity produced by the sun and then stored in the batteries.
On-grid/ grid-tied inverters
The on-grid or grid-tied inverters work by taking DC power and inverters it into AC power, thereby facilitating the power feeding into the electric utility grid. Grid-tied inverters are designed to take up DC supply and invert it into AC power grids to which they are connected, unlike the off-grid type.
The hybrid inverters are the latest versions being used in solar panel systems. They can combine solar inverters and battery inverters into one simplified unit. The hybrid inverters allow you to store off-peak energy that can be used during peak times. They work with solar batteries to store excess power to be utilized when the direct source is unavailable.
