A solar inverter is a device that converts the direct current coming from solar panels into alternating current, which we use to power everyday electrical devices such as vacuum cleaners, televisions, lamps, ceiling fans, air conditioners or heaters. An inverter is of course the main component of the solar power system that we install in our homes. We can’t run all devices on DC power and it gives us the more usable energy, that’s why we need an inverter. It is also referred to as the brain of the solar system.
Types of solar inverters
However, you should choose the type of solar inverter based on the load and the space available for a solar system. Here we will discuss the solar models to help you understand how they work and help you install the appropriate solar inverter.
To understand the solar function, there are three basic models.
- network connected
- off-grid system
- Hybrid system
Grid connected inverter

Solar inverters with MPPT controllers that are also connected to the utility grid are referred to as on-grid inverters. The inverter can provide additional power to the grid while also shutting down the solar system in the event of a power outage to avoid phase shift and other safety issues.
A grid-tied inverter that mirrors the utility’s grid based on production and consumption effectively and intelligently manages the energy supplied by the panels and the backup system.
Off-grid inverter

It is designed to work standalone with off-grid solutions for homes in remote areas without access to electricity.
In short, a pure sine wave is a repetitive oscillation that travels in smooth, arcuate waves and most closely resembles the flow of electricity in a distribution grid. For square and thick waves, the modified sine wave is sent to the home appliances.
Pure sine wave inverters are recommended for the safety and performance of home appliances because the modified wave does not transport electric power so smoothly.
Hybrid solar inverter

These inverters combine inverters and solar batteries into one unit. Some hybrid inverters include both on-grid and off-grid capabilities. You can use the energy generated by the panels yourself, feed it into the public grid or store it in batteries for later use.
The right inverter for your home
If you are considering purchasing a high capacity inverter for a large home with an average power consumption of 2,000 watts (2kW), consider the following considerations. The main thing people are usually looking for is solar inverter prices in India and then choose the best inverter that they can afford at a reasonable price. The types should be PWM and MPPT. Suitable capacity for solar inverters are 1KW, 2.5KW, 3KW, 5KW, 7.5KW and 10KW. The recommended batteries are 12V, 24V, 48V, 96V, 120V.

- MPPT – An MPPT inverter is usually a better choice than a PWM inverter as it charges the battery 30% faster.
- LED signals indicate whether the inverter is on, off or in standby mode for most inverters. At the same time, a digital display can provide information such as the amount of energy generated by the panels or the number of hours in which the solar system is generating electricity.
An LCD display helps homeowners understand inverter performance, including real-time monitoring of power generation, consumption, battery charge status, and causes of inverter failure. - The latest trend is to eliminate the LCD, settings and controls from the program on your phone or laptop. In addition, most inverters have the ability to collect data and instantly transfer it to your computer for easier viewing.
- Cooling System – In the above scenario, if the inverter is placed outdoors, the sun and the operating process may cause overheating. It is crucial to have a well designed, efficient cooling system.
If the inverter has Wi-Fi access, all functions of the LCD display can be monitored, managed and maintained online using the mobile app. - Bypass Switch – If an inverter fails, the home’s power supply will be disrupted; However, a bypass switch allows homeowners to use electricity even if the inverter fails.
- MCB Protection: An MCB protects the inverter from high voltage and short circuit failures caused by the constant voltage changes of the power grid and the possibility of a short circuit.
Solar Inverter Price in India 2022
A solar inverter accounts for about 25-30% of the total cost of a solar system. The top cost of solar inverters in India are listed below. Depending on the technology used, e.g. Whether it is off-grid, on-grid, or microinverter, the cost of a solar inverter can range from INR 6 to INR 20 per watt.
Inverter technology, efficiency, warranty length, and brand quality are all aspects that impact solar inverter pricing.

Efficiency, maintenance and guarantee
Since the solar inverter is an electronic component, it must be kept dry and dust-free. If there is a power fluctuation, short circuit or inverter failure, only the top manufacturers can repair and maintain it. A variety of factors affect the longevity of the inverter, one of which is the solar battery. Therefore, choosing the right battery is crucial. The capacity of a solar battery is measured in amperes per hour (Ah), which is a measure of how long a battery can power household items.
Off-grid inverters are 80 to 87 percent efficient, while grid-tied inverters are over 97 percent efficient. Off-grid inverters are only covered for 1-2 years in India, but grid-tied inverters are covered for up to 5 years.
The market is flooded with alternatives when it comes to choosing the right product for your needs, which can make it difficult. Loom Solar hopes the information on this page will help you make a more informed decision about which inverter is best for your solar panel system.
