Microinverters
Microinverters are installed directly behind each solar panel, converting DC to AC at the panel level. They offer higher efficiency since shading or malfunction in one panel does not affect the others. Although they are more expensive, microinverters are ideal for rooftops with shading issues or complex layouts.
Hybrid Inverters
Hybrid inverters combine the functionality of a standard solar inverter with the capability to integrate battery storage. They are perfect for households or businesses looking to store excess energy for nighttime use or power outages. With the rise of solar-plus-storage solutions, hybrid inverters are gaining popularity.
Central Inverters
Central inverters are large-scale solutions designed for utility projects and industrial setups. They function like string inverters but on a much larger scale, handling thousands of panels simultaneously. Their high efficiency and centralized monitoring make them suitable for solar farms.
Off-Grid Inverters
Off-grid inverters are used in standalone solar systems that are not connected to the electricity grid. They rely on batteries for energy storage and are commonly found in rural or remote locations where grid electricity is unavailable.
How a Solar Inverter Works
The process of converting solar energy into usable electricity involves several stages. When sunlight hits the solar panels, they generate DC electricity. This current travels to the solar inverter, where it is converted into AC electricity using advanced circuitry. The inverter then synchronizes the AC power with the local grid frequency, ensuring compatibility.
In addition, modern solar inverters incorporate MPPT technology to continuously adjust the panel output for maximum efficiency. They also include safety mechanisms that disconnect the system during abnormal voltage, frequency, or grid failures, protecting both the household and the grid.
