What is a 2 KVA Solar Inverter?

A 2 KVA solar inverter is an integral part of solar energy systems since these systems generate DC power, which can’t be used in homes. Household appliances run on AC power. And a 2 KVA solar inverter is responsible for converting the DC power generated by solar panels into AC power. 

The two main algorithms that solar inverters use are the PWM algorithm and the MPPT algorithm. It’s recommended to buy a solar inverter with an MPPT algorithm, as these ensure your solar panels operate at maximum efficiency throughout the day, regardless of temperature and sunlight. 

How Does a 2 KVA Solar Inverter Work?

A 2 KVA solar inverter works by converting DC power into AC power. Most modern solar inverters have a built-in MPPT (Maximum Power Point Tracking) algorithm to maximize panel output, and, in systems with batteries, the solar panel charge controller regulates DC charging to the battery bank. 

In on-grid solar systems, all DC power is first converted to AC before being sent to the house or exported to the grid. In off-grid solar systems and hybrid solar systems, part of the DC power is regulated for battery charging while the rest is converted to AC for appliances.

Here’s a step-by-step guide on how a 2 KVA solar inverter works: 

• Step 1 – DC power generated by solar panels goes to the solar inverter: The MPPT algorithm inside the solar inverter adjusts the voltage and current so your solar panels produce maximum possible power. 
• Step 2A – DC to AC conversion if it’s an on-grid solar system: The inverter converts the DC power from the panels into a steady AC flow, enabling household appliances to use it. If any excess energy is left, it’s sent to the grid.
• Step 2B – Smoothened DC power is sent to the battery bank if it’s an off-grid solar system: The inverter’s built-in charge controller sends part of the regulated DC power directly to the battery bank for charging. At the same time, it converts some DC power into AC to run the connected household appliances. Later on, when needed (at night or when there’s cloud cover and the panels do not produce enough electricity), the solar inverter draws DC from the batteries, converts it to AC, and powers the appliances.
• Step 2C – The solar inverter manages DC current for the grid and lithium batteries: During the day, DC power from the panels goes into the solar inverter. The inverter converts it to AC to run household appliances. At the same time, any unused DC is sent through the charge controller to charge the lithium battery bank. If the battery is full, the inverter sends extra AC power to the grid. At night or during a grid outage, the inverter takes DC from the battery, converts it to AC, and powers the loads. If the battery is low, it can draw AC power from the grid to keep loads running.
• Step 3: Continuous fault monitoring: The solar inverter is designed to continuously check for problems like overvoltage, overload, overheating, and grid faults. If it detects anything unsafe, it either shuts down or limits output to protect itself, the batteries, your appliances, and the grid.

What Are the Technologies and Types of 2 KVA Solar Inverters in India?

The two primary technologies used in a 2 KVA solar inverter when installing rooftop solar for housing societies, homes, and commercial and industrial purposes are the PWM and MPPT algorithms. On the other hand, the three main types of 2 KVA solar inverters are string inverters, microinverters, and power optimizers. 

Let’s check out the technologies and types of 2 KVA solar inverters in detail.

Technologies of 2 KVA Solar Inverters

The two primary technologies embedded in solar inverters are PWM and MPPT. These algorithms significantly impact the performance of solar inverters. 

• PWM technology solar inverters: These are now an almost obsolete type, and most solar inverters nowadays have MPPT technology. PWM stands for Pulse Width Modulation. The PWM algorithm reduces the panel voltage to match the voltage that batteries can handle without getting damaged. This results in a lot of power wastage since solar panels are unable to work at their maximum efficiency. 
• MPPT technology solar inverters: Most modern 2 KVA solar inverters use the MPPT algorithm since it ensures that panels work at their maximum efficiency at all times. Their efficiency is usually equal to or higher than 95%. These can be up to 30% more efficient than PWM inverters. 

Types of 2 KVA Solar Inverters

The three main types are string inverters, micro-inverters, and SolarEdge power optimizers. Out of these three, string inverters are 90% cheaper and most widely used for home and commercial installations since they’re quite affordable and suitable for rooftops that do not have shadow issues. 

• String inverters: In these inverters, all solar panels are connected in a series, called a string. The combined DC power is sent to a single inverter. The inverter then converts the combined DC power into AC power for household use. This design is cost-effective and simple. However, if one panel in the string produces less power because of shade, the whole string’s output drops. Therefore, these inverters are suggested for rooftops that do not have shading issues.
• Micro-inverters: Microinverters are small inverters attached directly to each solar panel. They convert DC to AC right at the panel itself. Since each panel works independently, shading on one panel doesn’t affect the power generation capacity of other panels. However, they cost a lot more than a single string inverter. String inverters, in general, are 90% cheaper. You should opt for a micro-inverter only if your roof is afflicted by shadows.
• Power optimizers: Power optimizers aren’t truly inverters. Instead, they’re small devices fitted to each solar panel. They don’t convert DC to AC at the panel. Instead, they improve the DC power from each panel before sending it to a central string inverter. This helps reduce the impact of shading on individual panels while still keeping the cost lower than using microinverters for every panel. 

2 KVA Solar Inverter Price in India in 2025

The 2 KVA solar inverter price in India depends on the brand you’re purchasing. For instance, an on-grid 2 KVA string solar inverter with MPPT technology by SunGrow can cost ~ Rs. 30,000*. Usually, the cost of a solar inverter is usually 25-30% of the entire solar system’s cost. 

*Please note: The price mentioned above for the 2 KVA string solar inverter is for illustration purposes only and may not reflect current pricing or offers. Actual prices can change without notice due to factors such as market conditions, model variations, your city, GST inclusion, and purchase agreements. 

The brand you choose has a significant impact, as premium brands like SunGrow offer high-quality products that last longer, come with better warranties, and provide excellent after-sales services. This means you’re never left without support after installation if the product malfunctions for any reason. 

Avoid opting for cheaper solar inverters just to save a few bucks, as their quality and performance can significantly reduce the overall performance of your solar system.

Features of a 2 KVA Solar Inverter

A 2 KVA solar inverter converts DC power from solar panels to AC power. It uses the MPPT technology to maximize solar panel output and prevent energy waste. 

Let’s check out all the features of a solar inverter in detail:

• DC to AC conversion: Solar inverters convert direct current (DC) from solar panels into alternating current (AC) so your home appliances can use it.
• MPPT technology: Inverters use the MPPT algorithm to find the best voltage and current levels from panels to get the maximum possible power.
• Battery charging (if applicable): Solar inverters send regulated DC power to charge batteries in off-grid or hybrid solar panel systems.
• Grid synchronization: For grid-connected solar systems, solar inverters match the grid’s voltage and frequency so they can safely send power to the grid in on-grid or hybrid systems.
• Real-time monitoring: These inverters let you check energy production via a screen or mobile app.
• Safety protections: These inverters are designed to offer protection against issues like overvoltage, overheating, short circuits, and grid faults.
• Anti-islanding protection: On-grid and hybrid solar inverters shut down automatically during a power cut to protect linemen.

What Are the Benefits of a 2 KVA Solar Inverter?

An on-grid 2 KVA solar inverter has an anti-islanding feature. As a result, the inverter automatically shuts down, and so do the solar systems wherever the grid is down. This is a specially designed feature incorporated in all on-grid solar inverters so linemen working on fault lines don’t get electrocuted. Moreover, these inverters have added protection features that ensure your appliances, as well as the grid, do not get damaged.  

Let’s check out the benefits of solar inverters in detail:

• They make the solar systems functional: Solar inverters convert DC power to usable AC power. Without them, a solar PV system would not have been safe for households. 
• They maximize solar output: The MPPT technology ensures solar panels always generate maximum possible power. Any surplus electricity units are exported to the grid rather than going unused.
• They protect appliances: Solar inverters have multiple in-built safety features that protect appliances and the grid from problems like voltage spikes and overloads. 

What Are the Disadvantages of a 2 KVA Solar Inverter?

Shading can impact the performance of a string solar inverter. Moreover, on-grid solar inverters shut down during power outages. These are certain limitations of solar inverters, but they can easily be overcome.

Let’s understand the limitations of solar inverters and also the ways to overcome them:

• They shut down during power outages: This means that during a power outage, the solar system cannot supply electricity to your home. However, this is an intentional safety feature in all grid-tied inverters that ensures linemen working to repair faulty sites never get electrocuted. While urban areas rarely experience frequent power cuts, residents of remote or rural areas with an extremely unreliable grid can utilize batteries, such as lithium batteries, to store power. This stored power can be used during power outages to keep appliances running.
• String solar inverters do not perform well under shadows: The output from string solar inverters can be reduced significantly if shadows fall on solar panels. However, string inverters are normally not recommended for roofs with shadow issues. In these cases, you can opt for micro-inverters or power optimizers. 
• High replacement cost: If your solar inverter malfunctions and requires replacement, it can be a significant financial burden. This is why you must focus on purchasing inverters by reputed brands that offer extended warranties and great after-sales services.  

2 KVA Solar Inverter vs Normal Inverter, Which is Better and Why?

A normal inverter can’t help cut down your electricity bills by 90%, but a solar inverter can. Since the latter converts DC power generated by panels that use solar energy, it reduces electricity bills significantly. Plus, it’s non-polluting, unlike normal inverters that use grid electricity to charge batteries. 

Here’s a head-on comparison between the two types to help you weigh which of the two is better and why:

Feature	Solar Inverters	Normal Inverters
Primary function	Converts DC from solar panels into AC for running appliances Can charge batteries and feed excess to the grid	Converts DC from batteries into AC for running appliances during a power cut.
Power source	Solar panels for on-grid solar systems Batteries for off-grid systems Batteries and grid for hybrid solar systems	Batteries only Charged from the grid or a generator
Solar compatibility	Directly accepts solar panel input (DC) Has built-in MPPT charge controller	Cannot connect directly to solar panels Requires an external solar charge controller to work with solar energy systems
Sending excess energy to the grid	On-grid and hybrid solar inverters can send surplus power to the grid for credits earned through net metering.	No grid feed-in feature
Energy savings	Reduces electricity bills by 90% since they use free solar renewable energy.	It does not reduce electricity bills because it uses grid power to charge batteries.
Upfront cost	Higher upfront cost: Usually, 25-30% of the total solar system installation cost. However, it significantly reduces electricity bills and can serve as the primary power source to keep the home running day and night.	Lower upfront cost Only for backup needs
