The grid-connected inverter is a special inverter whose output AC power can be synchronized with the frequency and phase of the mains power, so the output AC power can be returned to the mains power. The inverter can adapt to various harsh environments and apply in residences, factories and ground-mounted power stations. As an interface device between photovoltaic cells and the grid, the grid-connected inverter converts the electric energy generated by the photovoltaic cells into alternating current and transmits it to the grid, playing a vital role in the photovoltaic grid-connected power generation system.

Powerful and Innovation Functions

Grid-tied inverters are well-made with sturdy housings, and are easy to maintain. It can adapt to various harsh environments and is suitable for residential and public applications. Using air cooling to dissipate heat, the machine has a long service life. Excellent low-light automatic locking function (APL), the photovoltaic power generation system is more efficient. It pass TUV test and has corrosion resistance.
Meet Grid Needs

On grid inverters have high power generation efficiency and can make full use of solar cells. And it has less impact on the voltage of the power grid and has higher stability. This can not only meet the needs of the power grid, but provide more stable and safe power for the power grid, and can meet users' high standards and requirements for power generation systems. Since photovoltaic power generation systems are mainly used in remote areas, many power stations are unattended and unmaintained, which requires the inverter to have a reasonable circuit structure, strict component selection, and requires the inverter to have various protection functions.
Inverter used in grid

Installation of On Grid Inverter

Step 1:

Choose a ventilated and sun-protected location to facilitate heat dissipation and maintenance. Depending on the placement direction of the grid-connected inverter, you can choose an installation location facing east or west to make full use of solar energy. Ensure that the grid-connected inverter maintains a certain safe distance from surrounding objects to avoid overheating or collision.

Step 2:

Connect the solar panels, load, grid, etc. to the corresponding terminals of the grid-tied inverter according to the attached wiring diagram. Make sure the wiring is correct and secure. Use the included fixing device to fix the grid-connected inverter in the selected position to ensure stability and no shaking.

Step 3:

Connect the power cord of the on grid-connected inverter to the power grid to ensure that the power supply is normal.

On Grid Inverter FAQ

Can on-grid solar system work without batteries?

Yes, on-grid solar systems can operate without batteries. These systems, also known as grid-tied or grid-connected pv systems, are designed to generate electricity from solar panels and feed it directly into the utility grid. When the solar panels produce more electricity than the home or business consumes, the excess power is sent back to the grid. Conversely, when the panels aren't producing enough power (e.g., at night or on cloudy days), electricity is drawn from the grid.

Batteries are optional components in these setups. They are used to store excess solar energy for use during periods of low or no solar generation, providing backup power during grid outages. However, without batteries, the system relies solely on the grid for balancing energy supply and demand. This can be cost-effective for grid-connected locations with reliable power supplies but may leave the user without electricity during blackouts. The decision to include batteries depends on individual needs, budget, and energy resilience goals.

Can on-grid solar inverters store excess energy?

On-grid solar inverters are not designed to store excess energy. Their primary function is to convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used in your home or sent back to the grid. Any excess energy generated by the solar panels is typically fed back into the electrical grid, allowing you to earn credits or compensation through net metering or feed-in tariffs, depending on your location.

To store excess energy for later use, you would need a separate energy storage system, such as a battery. Energy storage systems like lithium-ion batteries can capture surplus energy during sunny periods and discharge it when your pv panels are not producing electricity, like at night or during cloudy days. These systems offer greater energy independence and allow homeowners to utilize their solar power even when the sun isn't shining.

What is the difference between on-grid and off-grid solar inverter?

On-grid and off-grid solar inverters serve different purposes in solar power systems.

Grid tied solar inverters are designed to work in conjunction with the utility grid. They convert the DC electricity generated by solar panels into AC electricity that matches the grid's voltage and frequency. These inverters allow excess energy to be fed back into the grid, earning credits or compensation through net metering. They do not provide power during grid outages, as they are dependent on a functioning grid connection.

Off grid solar inverters are used in systems that are not connected to the utility grid. They store excess energy in batteries for use when the sun isn't shining, providing a reliable power source in remote areas or during power outages. Off-grid inverters must manage the entire power supply, making them more complex and often requiring additional components like charge controllers and battery systems.

In summary, on grid inverters are grid-dependent and promote grid integration, while off-grid inverters are self-sufficient, providing energy independence in isolated locations.

How does an on-grid solar inverter connect to the electrical grid?

An on grid solar inverter connects to the electrical grid to efficiently convert and synchronize the direct current (DC) electricity generated by solar panels into alternating current (AC) that can be used in homes and sent back to the grid. The process involves several key steps:

1. DC to AC Conversion. Solar panels generate DC electricity, and the inverter's primary function is to convert this DC power into AC power, which is what the grid operates on.

2. Synchronization. The inverter ensures that the AC power it produces is synchronized with the grid's frequency and voltage. This synchronization is crucial for safe and efficient grid interaction.

3. Anti-Islanding Protection. Inverters have anti-islanding protection mechanisms to prevent them from sending power to the grid during grid outages. This protects utility workers and maintains grid stability.

4. Grid Connection. The inverter is connected to the home's electrical panel and, through that, to the grid. It monitors the grid's conditions and feeds excess energy back into the grid when the solar system generates more power than the home consumes.

How is the output of an on-grid solar inverter measured?

The output of an on-grid solar inverter is typically measured in several key parameters, with the primary ones being:

1. AC Power Output. This is the most critical measurement and is usually expressed in kilowatts (kW) or megawatts (MW). It represents the amount of electrical power the inverter converts from the direct current (DC) generated by the solar panels to alternating current (AC) that can be used in your home or fed back into the grid.

2. Efficiency. Inverter efficiency indicates how effectively it converts DC power into AC power. It's expressed as a percentage, and higher efficiency means less power loss during the conversion process.

Monitoring systems and utility meters often display these parameters, allowing homeowners and grid operators to assess the performance and contribution of solar installations to the grid.
