A grid-tie inverter (GTI for short) also called an on-grid inverter, is a special inverter. In addition to converting direct current into alternating current, the output alternating current can be synchronized with the frequency and phase of the mains. Can go back to mains. Grid-tied inverters are commonly used in applications where some DC voltage sources (such as solar panels or small wind turbines) are connected to the grid.
Differences Between Grid-Tie and Regular Inverter
Grid-Tied Inverters
Grid-tied PV inverters connect your home and supplement the electrical grid in case of surplus power generation. The inverter delivers power to your home appliances directly from the solar panel when the solar energy is available for use. It switches back to grid power in case there is insufficient solar energy. Grid-tied PV inverters work side by side with the mains to deliver energy to your home wherever needed. They have processing intelligence, enabling them to know when power delivery is necessary and when it is not. They also sync grid power with power delivery.
Regular or Off-Grid Inverters
Regular inverters cannot synchronize with the grid. Instead of working with the grid power, they only connect to the appliance in your house. They function alone. The off-grid inverter draws the power from a battery, converts it from direct current, and outputs alternating current. Regular inverters have to supply the power they convert from DC to AC instantly to the appliance. The energy must quickly react, be over, and up to the inverter’s capacity rating.
You can have a regular inverter for generating a grid and use a Grid-tied inverter to run all or most power in a hybrid system. An off-grid design is used when a solar panel is situated more than 20m from the battery. You can also use it if the power demand is immense during the day when there is a lot of sunlight. It is a way to use the most efficient solar power.
Functions of On-Grid Inverter
After sunrise in the morning, the solar radiation intensity gradually increases, and the output of the solar cell also increases. When the output power required by the on-grid inverter is reached, the inverter starts to run automatically. After entering into operation, the inverter will monitor the output of the solar cell module all the time. As long as the output power of the solar cell module is greater than the output power required for the inverter to work, the inverter will continue to run; it will stop at sunset, even if it is cloudy and rainy. The inverter can also operate. When the output of the solar cell module becomes smaller and the output of the inverter is close to 0, the inverter will form a standby state.
The output of a solar cell module varies with the intensity of solar radiation and the temperature of the solar cell module itself (chip temperature). In addition, since the solar cell module has the characteristic that the voltage decreases with the increase of the current, there is an optimum operating point where the maximum power can be obtained. The intensity of solar radiation is changing, and obviously the optimal working point is also changing. Relative to these changes, the operating point of the solar cell module is always at the maximum power point, and the system always obtains the maximum power output from the solar cell module. This control is the maximum power tracking control. The biggest feature of on-grid inverters for solar power systems is that they include the function of maximum power point tracking (MPPT).
Before the grid-tie inverter is connected to the grid for power generation, it needs to take power from the grid, detect the parameters such as voltage, frequency, phase sequence, etc. of the grid power transmission, and then adjust the parameters of its own power generation to be synchronized with the grid electrical parameters. It will be connected to the grid to generate electricity.
When an accident or disturbance in the power system causes a voltage sag at the grid-connected point of the photovoltaic power station, within a certain voltage drop range and time interval, the photovoltaic power station can ensure continuous operation without being disconnected from the grid.
During normal power generation, the on-grid power generation system is connected to the large power grid and transmits active power to the grid. However, when the grid loses power, the grid-tie power generation system may continue to work and operate independently from the local load. This phenomenon is called the islanding effect. When the islanding effect of the inverter occurs, it will cause great safety hazards to personal safety, power grid operation, and the inverter itself. Therefore, the grid connection standard of the inverter stipulates that the grid-tie inverter must have the detection and control function of the islanding effect.
Advantages of On Grid Inverter
Efficiency
The first benefit of installing on-grid solar inverters is their efficiency. The module efficiency is usually up to 98 per cent, which means that like solar energy in general, there is no concept of transmission loss, and no matter how much energy the system produces and the grid supplies to your residential or commercial setup, the inverter will tackle the job efficiently, always.
Cost-Effective
Solar inverters are generally expensive; both off-grid and hybrid inverters can cost a lot and will generally increase the return-on-investment (ROI) time. However, the most cost-effective option out of them all is the on-grid solar inverter, which is usually much more cost-effective and a lot less expensive, but delivers the same quality performance like the other two solar inverters on this list.
Ease of Installation
With an on-grid inverter, the ease of installation is incredible compared to off-grid and hybrid inverters. Since on-grid inverters usually don’t provide the ability to function during a blackout situation and do not support net metering, hooking them up to the house’s energy box is relatively simple and requires less time and complexity. As such, on-grid inverters usually get installed rather quickly. The fact that they are usually lighter and easier to handle than either off-grid or hybrid also helps with the installation time and ease.
Device Safety
An on-grid inverter includes a safety device that protects the on-grid solar system from electrical damage. For example, if an electrical arc occurs, the grid-tied inverter promptly shuts off the system.
Grid Assistance
In both directions, the on-grid solar inverter communicates with the electricity grid. This means the inverter will feed excess energy to the grid and pull electricity when needed. Furthermore, it detects any disruptions in the electrical grid, allowing the solar system to enter a safe mode. If the grid fails, the inverter can cut down the power source.
Power Production Tracking
The grid-connected solar inverter facilitates power production tracking. As a result, you can monitor how much excess power is generated during each cycle.
Application of On Grid Inverter
Distributed Power Generation System
In a distributed power generation system, solar PV arrays are converted from DC to AC using on on-grid inverter, which is then connected to the power network. This application makes it possible for the solar system to provide power for local power equipment and inject excess power into the grid, realizing a two-way flow of energy.
Solar Power Plants
In large solar power plants, hundreds of solar PV modules are connected to the power network via on-on on-grid inverters. The efficient performance and reliability of the inverters are critical to the overall operation of the solar power plant.
Home PV Systems
More and more households are choosing to install solar power systems that generate their own electricity and supply excess power to the electricity network via on-on on-grid inverters. This not only reduces household energy costs but also helps to minimize reliance on conventional electricity.
Commercial and Industrial Applications
In the commercial and industrial sectors, solar power systems are often used to power businesses. With on on-grid inverters, these systems have the flexibility to convert solar energy into electricity that can be used for production and operations, enabling the sustainable use of energy.
Working Principle of On Grid Inverter
The grid tie solar inverter’s working principle is just like a conventional solar inverter but with a significant difference: a grid tie inverter converts the DC output of your solar panels directly into AC. Then it synchronizes this AC current with the utility grid frequency. This is in contrast to a conventional off-grid inverter, which converts DC into AC and then regulates the voltage to match your system’s requirements, even if these are different from the utility grid. Here is what happens when you have a solar panel to grid tie inverter. During peak sunlight hours, the electricity produced by your solar panels may exceed household demand. In this case, the extra power will go to the grid, and you’ll receive a credit from your utility company. At night or during cloudy weather, when your solar panels are not producing enough power to meet your household demand, you’ll pull electricity from the grid as you normally would. An on-grid solar inverter must be able to shut down automatically when the utility grid goes down, as feeding electricity into a downed grid can be dangerous.
Components Required to Install Grid Tied Inverter
Isolators
They are key electronic components used in solar inverters as they enable communication between low-voltage sensitive control circuits (microcontrollers) and high-voltage components (power transistors).
Net Meter
It is like a tracking system that monitors power exchange between the home and the main utility grid. It calculates and credits the owners of solar panel systems for the electricity supplied to the grid from their solar power system.
Protection Unit
Grid-tied inverters have anti-islanding protection along with other inbuilt protection functions. But adding protection devices like charge controllers, safety switches, and cabling adds an extra layer to the entire system.
Solar Panels
These are the most essential components because inverters function by converting DC power generated by solar panels into AC power that is suitable for running appliances.
Wiring
Proper wiring with connection to solar panels, main electric panel, and net meter is required. The length, width, and quality of wire should be optimum for the purpose they are used.
Maintenance Tips for On Grid Inverter
Keep Inverter Cool
Inverters generate heat when they are in use. So it’s important to keep them cool and prevent them from getting too hot and damaging the electronic components inside. Solar inverter overheating is best prevented by ensuring a well-ventilated area and keeping the air vents open and debris-free.
Inverter Cleaning
Solar inverters need to be kept clean in order to operate efficiently. Dust, dirt, and debris can build up on the inverter and cause it to work less effectively. To clean your inverter, simply use a piece of cloth to wipe down the unit. Do so regularly, especially if the inverter location is prone to dust.
Note: the inverter air filter may clog with dust and restrict the free flow of air. This must only be cleaned by a professional.
Inverter Inspection
Periodically inspect your inverter for signs of wear and tear. Look for damaged wires or loose connections as well as scratches or other irregularities on the unit itself. These can all affect the performance of your inverter and should be repaired or replaced as soon as possible.
Inverter Error Codes
Be on the lookout for error codes if your inverter has a display for these. Some inverters may flash a light instead. A solar inverter red light simply means something is wrong, either with the inverter itself or other components such as ground faults. On the other hand, a technician will help interpret error codes.
Solar Inverter Repairs
If you notice any problems with your inverter, be sure to contact a qualified solar inverter technician for assistance. Timely repairs help to prevent bigger problems and save you heavier costs. Avoid DIY inverter repair. Trying to fix the unit yourself can void the warranty and cause further damage.
Factors to Consider Before Choosing an On Grid Inverter
Is Efficiency Really That Important?
An inverter’s efficiency is all about the power it takes from the solar panels, and converts into usable AC power. An efficient inverter reduces the loss of energy that usually happens while receiving DC from the solar panels. An efficiency of 50% indicates that the inverter is using very less amount of power. On the other hand, an efficiency of 90% denotes maximum utilization of energy, and which is considered to be the inverter’s rated output. In the recent times, the efficiency of the on-grid inverter is more than 98%. Most of the solar grid-tie inverter manufacturers offer a peak efficiency value. Peak efficiency value is the highest efficiency that the inverter can achieve.
Should We Really Think About The IP Rating?
Inverters are subject to harsh natural elements such as water, dirt, dust, high temperatures, low temperatures, fluctuating voltages, etc. Also needs to check and ensure the inverter can withstand harsh environmental phenomenon or not. It is advisable to ensure minimum of IP65 rating of inverter should be used. Also, if the inverter will be installed near to a sea/river coast, then take care the inverter should be coated with salt resistance material for more protection and longer life span.
Should We be Concerned About Installation?
Try to select the grid tie string inverter with simple and easy installation, the inverter should have brackets and all accessories to assist only one person to install. It will be great if the inverter can be installed behind the string modules, so can reduce connection cable length, and save some costs. Also, if the string inverter can be wired via single MC4 to be something like plug and play installation. Just we need to streamline installation process so reduce time and cost. Also, during installation need to keep in mind for the future expansion, so that the expansion can be done with ease.
Is the DC Input Voltage Much That Important?
This is the voltage range that the inverter will accept from the PV array. Local climate data and temperature coefficients will determine the maximum and minimum expected voltages. Exceeding the maximum voltage specification of an inverter may cause damage or fire in a worst scenario; and while it is not dangerous, too low array voltage can cause the inverter to stop processing power.
Why AC Output Power Should be Considered?
The inverter’s AC output power should be matched to the PV array. A PV array’s Standard Test Conditions (STC) power rating will provide a good idea of the minimum size of the needed inverter. For instance, a 5 kW PV array will require an inverter with about a 5 kW power output. If the climate interferes with the array preventing it from reaching STC power, it is possible to “undersize” the inverter by 10 to 20%. In that case, under-sizing would need a 4 to 4.5 kW inverter for that 5 kW PV array. The inverter may require ‘over-sizing’ for arrays in higher elevated areas which are colder and sunnier; this is to avoid power clipping. In addition, a larger inverter can capture random moments of high PV output, such as those from cold, sunny days or from ‘edge-of-cloud’ effect and possibly leave room for future expansion.

Q: What is an On-Grid Solar Inverter: What’s its role?
Energy Conversion
Most households depend on AC electricity. Therefore, the DC electricity generated in the solar system cannot be used in its original form. Instead, the grid inverter converts it into compatible 220 or 440-volt AC electricity, depending on the household requirement.
Ensuring System Safety
An on-grid inverter comes with a safety system to protect the on-grid solar system from electrical damage. For example, if there is an electrical arc, the grid-tied inverter shuts down the system immediately.
Regulating and Maximising Power Output
The on-grid inverter optimises and regulates the power output to deal with fluctuations.
Grid Assistance
The on-grid solar inverter allows two-way communication with the power grid. This means that the inverter will feed the grid with excess energy and draw energy when necessary. Moreover, it detects any disturbances in the power grid, allowing the solar system to switch to a safe mode. If necessary, the inverter can shut down the power supply if the grid fails.
Tracking Power Production
The grid-tied solar inverter allows easier tracking of the power production. Therefore, you can see how much excess power is produced during each cycle.
Q: What are the types of on-grid solar inverters?
These solar inverters are directly connected to the grid. They are the most widely used category of solar inverter for both domestic and commercial purposes. String inverters usually do not come with a battery backup. That being said, you do not need a battery in an on-grid solar system: the grid does the job.
Micro-Inverters
The Micro inverters are relatively smaller in size but costlier than the string inverters. This category of inverters usually comes with a capacity range of 200-350 W. Installed individually on the back of each solar panel, the micro-inverters are ideal for places where there is a disparity in the amount of sunlight received by an individual solar panel.
