Best On-Grid Solar Inverters in India (2024)

Looking to install a solar inverter for your solar project?
Don’t know which one best suits your needs?

We have researched the best On-Grid solar inverters for you that will help you make a more informed decision. But before that for those who are still curious about what a solar inverter is, here is a brief overview of it:

A Solar inverter is a crucial component of a solar energy system. The device has one primary function- to convert the raw DC power produced by the panels into usable AC energy. There are two types of inverters, each with a different manner of performing the same primary function.

1. A String Inverter converts energy from the entire solar array at one central location.
2. A Microinverter converts DC into AC at the level of each module, leading to lower DC losses.

There is a solar technology in the market that falls right between the string and microinverters. Inverters with Power Optimizers extract the maximum current at the module level before transmitting it to a central inverter for conversion.

In this blog, we have shortlisted the best solar inverter brands from each category to make your choice easier.
