The 3 Types of Solar Inverters Explained
Before you choose a brand, you must choose a type. This is the most fundamental decision.
On-Grid (Grid-Tie) Inverters: These are the simplest type. They connect directly to the grid and do not use batteries. They are perfect for homeowners whose primary goal is to reduce their electricity bill through net metering. They do not provide power during an outage.
Off-Grid Inverters: These are designed for remote locations with no grid access. They use solar panels to charge a battery bank, and the inverter then pulls power from the batteries to run your home. They are for complete energy independence.
Hybrid Inverters: This is the most popular and recommended choice for modern Indian homes. A hybrid inverter is the “best of both worlds.” It can connect to the grid to reduce your bills, but it can also charge a battery bank to provide backup power during an outage.
Which Brand of Solar Inverter is Best in India?
The Indian market is dominated by a mix of trusted local giants and high-quality international brands. Here’s an honest look at the top players.
Luminous & UTL: These are the undisputed leaders in the Indian home solar market. They have a massive service network, are known for their robust and reliable products (especially hybrid inverters), and are trusted by millions. You cannot go wrong choosing one of these.
Microtek, Smarten, & Havells: These brands offer fantastic value for money. They are strong competitors to Luminous and UTL, often providing similar features at a slightly more budget-friendly price point.
Growatt & Solis: If you are installing a pure On-Grid system, these international brands are often considered the gold standard for efficiency and reliability.

Frequently Asked Questions About Solar Inverters
A solar inverter is the brain of a solar power system. Its main function is to convert the Direct Current (DC) electricity that solar panels generate into Alternating Current (AC) electricity. AC is the standard form of power used by all appliances in your home, from your lights and fans to your TV and refrigerator. Without an inverter, the power from your solar panels would be unusable for your home.
For most Indian homes, a **Hybrid Inverter** is the best choice. This type of inverter works with the electricity grid to reduce your bills but also charges a battery bank to provide essential backup power during the frequent power cuts experienced in many areas.
Leading brands like **Luminous, UTL, and Microtek** are considered top choices in India due to their robust build quality, reliability, and wide service networks.
A normal inverter only has one job: to draw power from a battery and convert it to AC power for your home when the main grid fails. It cannot manage power from solar panels.
A **solar inverter** is much more advanced. It contains a built-in solar charge controller (like an MPPT) that allows it to intelligently manage power from three sources: the solar panels, the batteries, and the grid. It can use solar power to run your home, charge your batteries, and even send surplus power back to the grid, which a normal inverter cannot do.
The three main types of solar inverters are:
On-Grid (or Grid-Tie): These inverters are connected to the public electricity grid. They reduce your electricity bill by feeding surplus solar power to the grid, but they do not have batteries and will shut down during a power cut for safety reasons.
Off-Grid: These inverters are for remote locations without grid access. They use solar panels to charge a large battery bank, and the home runs entirely on the stored battery power. They are completely independent of the grid.
Hybrid: The most popular choice for modern homes, hybrid inverters are the “best of both worlds.” They are connected to the grid to save you money but can also charge a battery bank to provide backup power during an outage.
MPPT stands for **Maximum Power Point Tracking**. It is an advanced, highly efficient technology within a solar inverter’s charge controller. Its function is to continuously adjust the inverter’s electrical operating point to find the perfect voltage and current combination that will extract the maximum possible amount of power from your solar panels at any given moment. An inverter with MPPT technology can harvest up to 30% more energy than older technologies, especially in variable weather conditions like cloudy days.
Yes, in most cases, you can use a normal inverter battery (like a lead-acid tubular battery) with a solar inverter. However, batteries specifically designed for solar (often called C10 batteries) are built to withstand the deep and frequent charge/discharge cycles that are common in a solar power system. While your existing battery will work, a dedicated solar battery may offer a longer operational lifespan in a solar setup.
Connecting your inverter to WiFi lets you monitor your system’s performance. The general process is:
Check for a WiFi Dongle: Your inverter needs a small WiFi device, which either comes with it or can be purchased separately. This plugs into a specific port on the inverter.
Download the Brand’s App: Go to the Google Play Store or Apple App Store and download the official mobile app for your inverter brand (e.g., Luminous has the “ConnectX” app, Growatt has “ShinePhone”).
Follow In-App Instructions: The app will guide you through connecting your phone to the dongle’s temporary WiFi network, and then connecting the dongle to your home’s main WiFi router.
