Types of Solar Inverters

There are several types of solar inverters available to suit different solar panel system configurations and requirements. Here are the most common types:

i) On-Grid Inverters:

On-grid solar inverters are specifically designed to power appliances while also allowing the surplus electricity generated to be sent to the grid. However, it’s important to note that these inverters rely on the availability of sunlight to operate effectively. In cases of power cuts, your appliances will continue to receive the necessary power, but the grid will not be able to receive any excess electricity.

ii) Off-Grid Inverters

Off-grid solar inverters come in two main types: MPPT Solar inverters and PWM Solar Inverters. These inverters are designed to power your appliances while also allowing the surplus electricity generated to be stored in the battery. What sets off-grid inverters apart is their ability to operate even in the absence of sunlight, because of the energy stored in the battery. So, during power cuts, your appliances can continue to function hassle-free, drawing power from the battery.

iii) Hybrid Inverters:

Hybrid Solar Inverters fulfill the functions of both on-grid and off-grid solar inverters. They power the appliances and efficiently store any excess electricity in the battery. Once these tasks are fulfilled, hybrid inverters redirect the remaining electricity back to the grid.

How does a Solar Inverter Work?

The working of the solar inverter is explained in the form of the steps given below:

i) DC Electricity Generation: Solar panels capture sunlight and convert it into DC electricity.

ii) DC to AC Conversion: The DC electricity generated by the solar panels is not suitable for household appliances, which operate on AC electricity. This is where the solar inverter comes into play.

iii) Inverter Input: The DC electricity from the solar panels is fed into the solar inverter. The inverter is connected to the solar panel array, and it typically has a maximum DC input voltage and current rating that must not be exceeded.

iv) Conversion Process: Inside the solar inverter, there are electronic components, including transistors and capacitors, that perform the conversion. The main process involves switching the DC input on and off rapidly, creating a waveform that approximates a sinusoidal AC waveform.

v) Synchronization with the Grid (On-Grid Inverters): In the case of On-grid solar inverters, they power the appliances while also allowing the surplus electricity generated to be sent to the grid.

vi) AC Output: The solar inverter then produces AC electricity with the appropriate voltage, frequency, and waveform. This AC electricity is sent to the building’s main electrical panel to power appliances, lights, and other electrical loads, and the excess electricity is sent back to the grid in grid-tied systems.

Price Range of the Solar Inverter

The price of the solar inverter varies depending on the capacity of the inverter.

Hybrid Inverter- For a hybrid inverter the price starts from INR 1,00,000 for 5 kva inverter and goes up to INR 10,00,000 for a 100 kva inverter
Off-grid Inverter– For an off-grid inverter the price starts from INR 7000 for 1 kva inverter and goes up to INR 2,00,000 for a 15 kva inverter
On-grid Inverter– For an on-grid inverter the price starts from INR 50,000 for 2 kva inverter and goes up to INR 7,00,000 for 250 kva inverter.

People are moving to clean, renewable energy to help make the world a greener place, and solar energy is one of the most popular options among homeowners. When transitioning to solar energy, homeowners can select between a grid-tied solar system and an off-grid solar system. Because a grid-tied solar system is connected to the city’s power infrastructure, homeowners are advised to utilize an off-grid system to avoid any issues with the city’s electricity grid.

When connected to the electrical grid, power outages can occur for a variety of causes, and they can last anywhere from a few minutes to several weeks, an off-grid solar system may store energy in batteries for use during outages, and households can even withdraw from the grid and rely solely on the system for power.

What is an Off-Grid Solar System?

An off-grid solar system is a solar panel system that generates electricity from the sunrays and stores it in the battery. It is designed to run independently of the power grid. Because an off-grid system is not connected to the power grid, it requires battery storage. Off-grid solar systems must be appropriately constructed to generate enough power throughout the year and have enough battery capacity to meet the home’s needs, even when sunlight is sparse in the dead of winter.

Going off the grid eliminates the need to pay monthly electric bills. While the system is pricey, the fact that you won’t have to pay any electric bills in the long run is beneficial because it allows you to save money for other things.

Off-grid systems are substantially more expensive than on-grid systems due to the high cost of batteries and off-grid inverters. As a result, they are usually only needed in more rural places that are far from the power grid. However, as battery prices fall, the market for off-grid solar battery systems is expanding, even in cities and towns.

Off-Grid Solar Systems Working

Off-grid solar power systems, also known as stand-alone power systems, are one of the most common forms of solar power systems (SAPS). It operates by using solar panels to generate power, which is then used to charge a solar battery via a charger controller. The electricity is then converted using an inverter to power the appliances in the home or company. It is feasible to power a home on solar energy even at night or when there is less sun exposure by storing electricity in a solar battery.

Because remote areas have little infrastructure, connecting to the electricity grid can be difficult for residents, making off-grid solar systems ideal for such situations. Because solar panels require sunshine to collect electricity, mounting them on roofs is sufficient. Staying off the grid and using solar energy allows people to enjoy the benefits of power without having to pay monthly electric bills or connection fees.

Off-grid solar systems are ideal for providing consumers with clean, renewable energy. Solar energy allows homes to help make the world a cleaner and greener place, especially when they are cut off from the power grid.

There are other types of off-grid systems, which we shall discuss in greater depth later, but for now, let’s keep it simple. The diagram above depicts a larger AC-linked system. In smaller DC-coupled systems, a solar charge controller manages battery charging, after which the DC power is converted to AC and transmitted to your home appliances via an off-grid converter.

Off-Grid Solar Power System Components

Solar Panels – The quantity of available sunshine in the location, the useable space on the roof, and energy consumption needs will all influence the size and production capabilities of the individual solar panel array, which is the first element.

Batteries – A solar battery is required to keep the house running after the sun has set. As solar panels create excess electricity, the solar storage device will charge throughout the day. Rather than wasting all of that potential solar energy, a battery allows it to be saved for later use. A single battery, or perhaps a battery bank, is employed depending on the energy requirements.

Inverters – Solar power systems require a solar inverter, also known as a solar converter or a PV inverter, to convert the direct current (DC) gathered by solar panel arrays into alternating current (AC) for running most typical household appliances and gadgets. Use a stand-alone inverter for an off-grid installation.

Solar Charge Controller – To save the battery, a solar charge controller or battery charger is required. To prevent overcharging and damage to the solar battery, the controller limits the voltage and current it gets.

Alternative Energy Source – It could be worthwhile to investigate a backup energy supply for the system. This is especially important during the winter months when solar generation is at its lowest. Many people who employ off-grid systems pair them with a generator to meet their home’s power needs.

Off-Grid Solar Systems Advantages

Off-Grid Solar Systems Have a Lot of Benefits

1. No connection to the power grid – In some distant places, off-grid solar systems may be less expensive than extending power lines.

2. Self-sufficient in terms of energy – Another significant benefit of getting off the grid is complete independence from electricity sellers. You won’t have to pay anything for electricity, and you’ll be completely protected from growing energy prices.

3. Outage Protection – The system also guards against grid-connected power outages or blackouts. It feels fantastic to be self-sufficient and live off the grid.

4. Reliability – Self-sufficiency in energy is also a type of security. Off-grid solar systems are unaffected by power outages on the utility grid.

Conclusion

Not only will you save a lot of money on your electricity bills in the short term, but you can expect your home solar panel installation cost to be more than recouped in full when you sell your property. You can also anticipate a quicker sale of your home.
