This conversion is crucial because most appliances and electronics operate on AC power, and the on-grid inverter ensures compatibility.
In addition to the conversion function, an on-grid solar inverter also plays a vital role in system safety. It is equipped with features that can detect and shut down the system in the event of an electrical arc, protecting both the system and the household from potential hazards. This safety mechanism ensures the smooth operation of the solar power system and minimizes the risk of electrical accidents.
Another important function of an on-grid solar inverter is to optimize and regulate the power output. It monitors the solar energy production and adjusts the power output to deal with fluctuations in sunlight intensity. This optimization ensures that the system operates at its maximum efficiency and maximizes the energy production from the solar panels. The grid-tied solar inverter also allows for two-way communication with the power grid, enabling the feeding of excess energy back into the grid and drawing energy from the grid when needed.
Table: Comparison of String Inverters and Micro-Inverters
| String Inverters | Micro-Inverters | |
|---|---|---|
| Installation | Connected to the grid | Installed individually on each solar panel |
| Efficiency | Slightly lower due to voltage drop | Higher due to panel-level optimization |
| Shading | Performance reduced if one panel is shaded | Not affected by shading on individual panels |

String inverters are commonly used in residential buildings for their ease of installation and cost-effectiveness. These inverters are directly connected to the power grid, allowing excess energy to be fed back to the grid and reducing electricity bills. They are suitable for small to medium-scale residential solar installations.
Micro-inverters, on the other hand, are ideal for situations where panels receive different amounts of sunlight due to shading or orientation. By installing micro-inverters on each panel, the system’s overall efficiency is maximized, ensuring optimal energy production. These inverters are commonly used in residential rooftops where shading may be an issue.
Commercial and Industrial Applications
For larger-scale applications such as commercial buildings and industries, high-capacity central inverters are used. These inverters are designed to handle the higher power demands of such establishments and can be tailored to suit specific requirements. They are typically used in grid-tie solar installations on commercial rooftops, warehouses, and factories.
| Type of On-Grid Solar Inverter | Application |
|---|---|
| String Inverter | Residential buildings |
| Micro-Inverter | Residential buildings with shading issues |
| High-Capacity Central Inverter | Commercial and industrial buildings |
Hybrid solar inverters are another option for those who require a battery backup system. These inverters allow energy to be stored in a battery bank, providing power during grid outages or during peak demand periods. They are versatile and can be used for both domestic and commercial applications, offering the benefits of grid-tied systems with the added advantage of backup power.
