In India, the term “inverter” is often used synonymously with emergency power supply systems. You must have heard that people installed an inverter in their home to fix power outages.
However, if you are planning to install a solar array in your home to generate electricity, the need for an inverter can often seem confusing. You can only think of a solar system as a combination of solar panels, which is not true. Complete solar solutions offer a package of Solar reversal, Solar panels and batteries. Renowned brands like Luminous India offer the best solar solutions under one roof.

Before buying a solar inverter or a complete solar package, you need to know what a solar inverter really is and how it works.
What is a solar inverter?
A solar inverter converts the direct current (DC) received from a photovoltaic solar module (PV) into alternating current (AC). You can then use this alternating current to power various appliances and electrical appliances at home.
How does a solar inverter work?
When sunlight falls on the surface of solar panels, electrons are released in the solar cells and bus bars collect the traveling electrons, creating an electric current. Since most electrical devices are operated with alternating current, a solar inverter plays a decisive role here. The direct current from solar panels is then fed into the inverter, which converts it into alternating current. If the installed solar modules produce excess electricity, you can also feed this into the local power grid. Make sure you calculate your household electricity needs and match them with the solar inverter you bought. There are online load calculators to help you with this.
In addition to knowing how a solar inverter works, it is important to understand three main types of solar inverters in order to make a careful purchase decision.
Off-grid solar inverters work like normal inverters. They are generally used in areas where there are more power outages. These solar inverters work a little differently because the direct current generated by the solar panels is first stored in the batteries. In the event of a power failure, the solar inverter converts the direct current stored in the batteries into alternating current to meet the needs of households. Off-grid solar inverters from well-known brands such as Luminous offer Solar NXG + inverters a built-in charge controller. In addition, it has a unique iSOT technology that can save up to 3 units of electricity per day, which also leads to significant savings.
This type of solar inverter is directly connected to the power grid, hence the name. The inverter converts the generated direct current into direct current, which is then used by electrical appliances in the home.
The excess electricity generated by the combination of solar panels and inverters is automatically fed into the power grid via a bidirectional meter. In the event of a power failure, the inverter will stop to act as a safety feature called anti islanding. However, since there is no battery backup, you will not have access to power during a power outage. For this reason, grid-connected solar systems can be used in areas where there are seldom or fewer blackouts.
A hybrid solar inverter is used to manage the inputs from both solar modules and the grid. It charges a battery with the electrical energy of the solar system or the power grid and helps in the following situations:
- If your home’s electricity consumption is lower than that produced by a hybrid solar system, the excess energy is stored in batteries connected to that system.
- If your home uses more electricity than the electricity it produces, the excess demand is met by batteries.
The excess energy generated by such solar systems flows back into the grid. You can buy the solar inverter either with the solar system or separately.
How to choose a solar inverter
When choosing the best solar inverter, you need to understand your requirements. If you live in an area where there are more blackouts and load shedding, you will need to purchase an off-grid solar inverter. However, if there are comparatively fewer power outages, you will have to buy a grid-connected solar inverter. When looking for solar inverters online or offline, you need to consider a reputable brand like Luminous.
Luminous India’s Solar Home UPS – NXG + 1600 is an excellent option for home installation. It can charge the battery from the grid as well as from solar energy, with the latter having priority. The technical specifications also include a nominal AC power of 1100 VA, 24 V, a charge regulator power of 40 amps / 12 V at 98% efficiency and a sine wave power.
