The solar hybrid inverter, as the name implies, is a cross between typical on-grid and off-grid inverters proving how efficient is a hybrid inverter. During normal operation, the hybrid inverter synchronizes with your utility electricity and supplements your power consumption during the day with solar power. In this article, you’ll learn about hybrid inverters in detail like how does a hybrid inverter work and many other aspects.
How Does a Hybrid Inverter Work? What is the Working Principle of Hybrid Inverter?
To understand how does a hybrid inverter work, we must first learn about the operation of numerous essential electrical concepts involved in the working principle of hybrid inverter.
An inverter is a device that converts DC (direct current) power into AC (alternating current) power. This is what a solar system uses to power your lamps, appliances, and other electronics. In our homes and companies, alternating current (AC) is the standard kind of power.
2. Alternating Current vs Direct Current
Direct current, as the name implies, is an electric current that runs in only one direction. Alternating current, on the other hand, reverses its flow numerous times every second.
When DC enters the system, the inverter begins converting it to AC power using a process known as pulse width modulation (PWM). PWM is the way through which the inverter controls the amount of power transmitted to the grid. It operates by rapidly switching the DC current on and off so that the average voltage output is equivalent to that of AC. This all happens within the inverter in milliseconds. The alternating current power is then distributed to your home or company to run your appliances.
A rectifier would be required if you possessed AC energy and wished to convert it to useful DC power. A rectifier functions similarly to an inverter in that it converts alternating current (AC) energy into pulsed direct current (DC), which can then be readily stored in your system’s batteries. The process of converting from AC to DC is known as rectification.
4. The Hybrid Inverter
A hybrid inverter is an inverter and a rectifier in one compact unit. It can take DC power from solar panels and convert it to useful AC power in your home, in addition to utilizing the grid’s AC electricity to charge your DC batteries.

5. Energy Storage with Batteries
Battery energy storage is the final component of the puzzle. Because solar power generation varies (due to adverse weather, for example), it is not always possible to use solar power as it is created. Batteries are essential for any solar energy system because they allow you to store energy from your solar panels for later use or in the case of a grid interruption.
Batteries store direct current (DC) power, which your solar panels generate. As previously stated, inverters may convert this DC electricity to alternating current (AC) for usage in your home or business. Your inverter can also charge your batteries by redirecting any excess energy from your solar panel that isn’t being used at the time to the battery rather than your appliances.
Hybrid solar inverters use both solar and conventional power sources. It works as a whole. Solar inverters, for example, can combine solar energy with energy from batteries. Greener hybrid solar inverters can be created by combining solar and wind electricity. Let’s move ahead and understand the working principle of hybrid inverter.
a) Solar inverters transform the energy generated by photovoltaic panels into usable energy for the home. A solar system’s photovoltaic panels, often known as solar panels, capture solar energy.
b) Photons are little packets of energy that make up sunlight. These photons are absorbed by photovoltaic panels, which turn the light energy into electricity. Electrons in photovoltaic panels can be dislodged from their outer shells when photons strike them.
c) Electron photons push electrons out of their shells, releasing them. After that, the electric field pulls these liberated electrons in the appropriate direction. This is how it creates power. This power, however, is direct current.
d) The inverter’s role now is to convert this electrical energy into a useful form. It accomplishes this through the use of insulated gate bipolar transistors (IGBTs). IGBTs are solid-state devices, which means they are electrical instruments that allow current to flow through them. Furthermore, they are long-lasting and consume less electricity.
e) A backup system is also included with the hybrid solar inverter. This is usually a battery. As long as more energy is available, it assists the inverter in storing energy in the battery. This energy can be used when needed. As a result, in an emergency, it can offer energy.
f) Solar and wind energy can also be combined using hybrid solar inverters. It may also include a backup battery. It manages electricity and, when necessary, switches to solar, wind, or batteries.
What Does a Hybrid Inverter Do?
With solar panels being erected on rooftops all over the world, the hybrid inverter is a crucial step towards a simpler, more seamless green energy setup. But exactly what is a hybrid solar system, it is actually an electronic gadget that allows solar panels, batteries, and the regular electric grid to work together rather than separately.
A hybrid inverter is a type of electronic equipment that combines the operations of a microinverter and a battery charger into a single device. It enables solar panels to intelligently transfer extra energy into batteries, which is significant because solar energy production is at its greatest during the day while energy demand is at its peak in the evening.
Hybrid inverters are frequently used in conjunction with solar PV systems to provide grid-tied and off-grid configurations. They’re also utilized in microgrids, which are small-scale electrical networks that can run independently or in tandem with bigger power grids.
A hybrid inverter is similar to a regular inverter with the added benefit of being able to function with an AC source, such as the utility company’s grid electricity going into your home. This gives you more options for how you utilize your solar PV system, as you can now use the grid or your solar panels as your primary power source, or run your home entirely on solar power. This should have made you understand what does a hybrid inverter do.

How Long Do Hybrid Inverters Last?
So now that it’s clear how does a hybrid inverter work do you not want to know how long do they last? Solar inverters are becoming increasingly popular as electricity prices rise and people grow more ecologically conscious. There are numerous producers of solar inverters nowadays, and when it comes to what questions to ask before getting solar panels people often get increasingly picky, questions like how long do hybrid inverter last strike one’s mind the most. There is no doubt that we all want to select a solar inverter with a long lifespan in order to minimize our financial losses.
A solar system’s lifespan, according to experts, is between 25 and 30 years. However, the lifespan of a solar inverter may be limited. Most inverters have a lifespan of 10-15 years. Solar inverters, on the other hand, can last up to 25 years, depending on a variety of criteria such as the kind, brand, or model of the inverter. But in particular when we talk about how long do hybrid inverters last then the answer would be.
A hybrid solar inverter has a lifespan of up to 15 years. A solar hybrid inverter is a string inverter with a battery charging and discharging system. A solar hybrid inverter is a device that combines the operations of a battery inverter and a string inverter. Although hybrid solar inverters are less expensive than buying two inverters separately, their usefulness is reduced. You can utilize the inverter even if you don’t have solar cells by constructing a hybrid inverter.

How Efficient is a Hybrid Inverter?
Hybrid inverters, which are used to store extra solar energy to improve self-consumption and provide backup power, are at the heart of any simple, cost-effective solar battery storage system. These inverters function similarly to solar inverters but additionally include an integrated battery charger and connection in a single unit. Hybrid inverters require an external energy meter (CT) to measure power use and software that may be customized to calculate the most efficient use of your available solar or battery energy in order for the system to know when to charge or discharge the battery.
A hybrid inverter (also known as a multi-mode inverter) is an all-in-one device that performs three distinct purposes. It includes an integrated solar charge controller that connects to the solar panel(s) and regulates the voltage from the solar panel output to the loads and/or batteries. It should be noted that utility power and generator power are frequently used as inputs for incoming energy. A hybrid inverter provides many system design possibilities, giving you the freedom to apply the best solution for your specific needs.
This product inverts the current from the solar panels’ direct current (DC) to alternating current (AC), allowing standard household and business appliances and equipment to operate. The utility system may be able to use the electricity generated by the solar panels if it is authorized in the local area. Because each cycle contains a rise and fall, the alternating current would travel through zero 100 or 120 times per second.
The hybrid inverter also functions as a battery charger, drawing power from the PV system and/or an AC source to charge the batteries. The stored energy in the batteries can then be utilized at a later time. So that is how efficient is a hybrid inverter in its functionality.
