On Grid, Off Grid İnverter Nedir?

Grid-connected and off-grid inverters.

An inverter is a device that converts direct current (DC) from a DC source into alternating current (AC). Inverters are divided into two groups: on-grid and off-grid. On-grid inverters are systems connected to the grid and are used in solar energy electricity generation. Off-grid inverters are systems not connected to the grid. The difference between these two systems is that off-grid inverters allow for the storage of excess energy, while on-grid inverters do not allow for the storage of generated energy. With renewable resources becoming increasingly prominent, solar energy systems are gaining even more importance today.

What is an On-Grid System?

On-grid inverters , also known as grid-connected inverters , are systems that are connected to the central electricity grid and use solar panels to generate electricity. In grid-connected electricity generation systems, any energy generated is transferred back to the grid. This eliminates the need to use all of the generated energy.

On-grid systems can be used in situations requiring a large amount of power, as well as in homes with low energy needs. By installing panels on the roofs of houses, the advantage of reducing electricity consumption from the grid can positively impact utility bills. A major advantage of on-grid inverter systems is the ability to store excess energy. This excess stored electricity can then be sold, generating additional profit. Beyond this, various other advantages are offered by different types of on-grid inverters.

What are the main components of on-grid inverter types?

Grid-mounted solar energy systems, an alternative used in electricity generation, consist of three main components: solar panels, inverters, and bidirectional electricity meters.

Solar panels are used in grid-connected solar energy systems as transmitters, transmitting the generated energy back to the grid. Therefore, ensuring a sufficient voltage level during transmission is crucial. This is where the importance of panels becomes apparent. It's important to understand that panels affect the current according to their power rating, and this detail should be considered in studies.

Inverters are the main component in grid-connected systems. They are responsible for converting energy from solar panels into alternating current energy, which is why they are so important.

A bidirectional electricity meter performs the same function as a bidirectional meter. It transmits electrical energy from the grid to the area where it will be used. Unlike a bidirectional meter, it also transmits electrical energy that may come from an external source, i.e., from the grid.

What are the benefits offered by on-grid inverter systems?

• The systems used do not require employees, thus eliminating the cost of hiring staff.

• The energy obtained is directly converted. Therefore, the potential loss rate is minimized.

• Since there will be no need for devices like batteries to store the excess energy, there will be no need to allocate funds for energy storage devices.

• Because it has storage capabilities, energy can be transferred from the grid when there is insufficient sunlight to generate energy.

• On-grid inverter systems are flexible devices.

• The power of the systems can be increased depending on the size of the area where the installation is carried out.

Applications of On-Grid Inverters?

• In living areas, such as urban areas, villages, and towns.

• In areas where industrial activities take place, such as factories and workshops

• Lighting, especially indoor lighting

·In parking lots or garages

Areas where logistics operations are carried out and cold storage facilities are required.

• Stores, supermarkets, shopping malls

These are some of the application areas for on-grid systems. Due to the increasing prevalence of renewable energy sources, these application areas may also increase. Today, they can be used in almost every field where energy is needed.

What are Off-Grid Solar Energy Systems?

Off-grid inverters are one of the alternatives used in areas where grid electricity is unavailable, grid connection costs are high, and power outages are frequent. Known as off-grid solar energy, these inverters are a method used to harness solar energy.

Off-grid systems operate on the principle of generating electrical energy from sunlight using panels throughout the day. This process is directly proportional to the intensity of the sun's reflection. The higher the intensity of the reflected light, the more energy will be obtained. Because it is not connected to the grid, it will continue to produce energy year-round whenever it has sufficient power. Since the energy produced is used immediately, there is no possibility of storing excess energy.

Applications of Off-Grid Solar Energy Systems

• High-altitude areas with difficult access, such as mountain pastures and vineyard houses.

• Within irrigation systems in the agricultural sector

· In vehicles such as caravans and boats

·In communication stations

• In Security Systems

These areas are ideal for Off-Grid ( Grid-Free) inverters . Off-Grid solar systems are generally needed in situations where there is an energy demand that cannot be met from a central source.

Advantages of Off-Grid Inverters

• These systems do not strain the budget, except for the initial costs incurred during the studies.

• These are systems that do not generate operating costs.

• The yield rate is high and the loss rate is low.

• Assembly is easy.

• No dependency on any storage location.

• The effective areas of the systems can be increased as needed.

These are the main advantages of off-grid solar systems.

What are the components of off-grid energy systems?

Off-grid inverters, an alternative inverter option used in solar energy systems, consist of solar panels, batteries, and a charge controller.

Solar panels are systems that provide the sunlight needed for inverters to generate electrical energy. Because they form the first and fundamental step in the process, panel selection is crucial. If energy cannot be obtained, the process of converting that energy into electricity will not occur. Therefore, careful planning for this step is essential when initiating the project.

Charge controller: Its main function is to regulate the energy coming from the panels and use it to charge the batteries. In addition, it protects against reverse current in the panels and against overcharging of the batteries.

Batteries: These are the most fundamental components in the operation of off-grid systems. Therefore, accurately determining their capacity is crucial during the battery selection process. Furthermore, batteries must be long-lasting, resistant to high temperatures, and have high safety measures against gas leaks. In this context, the points to consider when determining battery capacity are:

A battery with a capacity greater than the daily energy consumption should be selected. The number of cloudy days should be taken into account to ensure maximum efficiency.

The power rating of the inverters to be used is also a factor to consider when selecting batteries.

Battery capacity should be determined according to the weather conditions of the region where it will be used. Climate transitions will differ between continental climates and regions with high rainfall. This detail should be considered during the battery selection process.
