Solar energy is growing fast in India. Many homeowners and businesses are installing solar power systems to save money and reduce electricity bills. A very important part of any solar system is the solar inverter. It converts electricity from the solar panels (DC) into usable power for your home (AC).
In 2025, three inverter brands are leading the Indian market — SMA, Fronius, and Huawei. Each brand has different features, benefits, and price points. In this article, we compare them in detail to help you choose the best solar inverter in India for your needs.
What Does a Solar Inverter Do?
A solar inverter changes the direct current (DC) electricity produced by solar panels into alternating current (AC), which powers your lights, fans, and appliances.
There are three main types of solar inverters used in Indian homes:
- String Inverters – most common for rooftop solar systems
- Hybrid Inverters – support battery backup
- Micro Inverters – one installed with each panel (less common in India)
