In order to make the right decision in choosing a solar inverter, you need to know your system needs. Under market conditions, inverters are offered for sale with many brands. It is very important to determine which inverter brand is the best among the inverter brands that produce electricity from solar energy.
So what is the best solar inverter hagi? Comparisons between inverters are usually made with the datasheet information of the product. Is it a 3000W 3kW inverter? Is it a 5 kW Inverter? Tommatech inverter? Mexxsun Inverter? Goodwe Inverter? Or Huawei Inverter? Full sine or modified sine inverter? If you say full sine inverter, should it be a grid supported smart inverter? Do you need a fully charged sine inverter? What is a hybrid inverter? Or is it an on-grid inverter? You will find answers to many questions that confuse you. We will be the farmer for you to decide on the best solar inverter model – brand according to your needs.
You can see many types of Inverters in the market. They are generally divided into different types of inverters in terms of their functions and areas of use. We will share the key features of all the inverters you have heard of.
What is Solar Inverter? What Does a Solar Inverter Do?
Solar inverters, also known as power converters or inverters in the market, are also called inverters. One of the most basic elements of electricity generation systems from solar energy is the inverter.
While DC (Direct Current) current is produced from the sun's rays with solar panels, the devices we use in the city grid work with AC (Alternating Current) current. All appliances in our homes such as refrigerators, televisions, dishes and lighting work with AC current. The inverter briefly converts the DC current to the AC current we need. It is a 220V converter. In order to use the electricity produced in solar systems, we need an inverter with a cutoff.
Solar inverters are not only used for DC-AC conversion. It provides performance monitoring in solar powered systems. Thus, it plays an important role in the detection of any malfunctions that may occur and in solving the problems. You can also store the excess generated energy or direct it to the grid with grid-supported (suitable Inverter) inverters. The inverter ensures safe operation of the system. It provides integration with grid or solar battery (solar battery).
One of the least mentioned but most important tasks of inverters (appropriate Inverter) is to act as a fuse on the system. In the solar system, it protects the devices in high current coming from your network.
What are the Solar Inverter Types?
There are two basic categories of inverters according to the operating wavelength (use cases).
1- Off Grid Inverters
There are three basic categories of inverters based on their use cases.
1- Off Grid Inverters
3- Hybrid Inverter
Off-grid inverters are used for systems where there is no grid. Off-grid inverters are generally used in systems with storage.
Off Grid Inverter has 2 types among itself.
There are different types of full sine inverters among themselves.
Hybrid Inverters: Hybrid inverters are devices that offer solutions to both grid-connected (on-grid) systems and off-grid systems. In the market, these are also known as Smart Inverters.
Inverters are grouped by operating wavelength. All sine inverters operate with full sine wavelengths.
There is a charge controller inside the Full Sine Intelligent inverter models. Solar charge controller varies as PWM or MPPT. You can monitor the system and make many adjustments with the display panel on the full sine smart inverter. In case of malfunction, error codes are displayed on the LED screen, thereby identifying the error. What are Smart Inverters error codes? Below are the most common error codes and error causes.
- Fan Fail inverter off
- extreme temperature
- Battery voltage too high
- Battery voltage too low
- Output short circuit or over temperature
- Output voltage is abnormal. (For 1K/2K/3K model) Output voltage is too high. (For 4K/5K model)
- overload timeout
- Common bus voltage too high
- Common Bus start error
- Mains Relay fault
Smart inverters also have mains or generator input. You can activate the generator when your renewable energy sources are insufficient.
With smart inverters, you can charge your batteries with mains energy at the same time.
Another feature is the parallel connection feature available in 5 kW models suitable for the system. With this feature, the current is shared by connecting more than one inverter in parallel.
In fully sine charged inverters, you can charge your batteries anywhere there is a grid. Inverter type recommended for caravans and boats.
Let's compare the battery charging feature of the charged inverters and the smart inverter. Intelligent inverters also have a high no-load draw current. Energy from the battery is used for its operation. This is an undesirable feature.
NOTE: Devices working with the city network work with full sine wavelength. It is more recommended for use than Modified Sine Inverter.
NOTE: All inverters except modified sine inverters are full sine inverters. While modified sine inverters operate with square wavelength, full sine inverters operate with full sine wavelength. Most of the electronic devices we use in our daily life operate at full sine wavelength. For this reason, it is recommended to choose full sine inverters.
Modified Sine Inverters have different types among themselves.
There are charged models in Modified Sine Inverters. Thanks to the modified sine-charge inverter, you can fill your batteries when the grid is available.
What Are Off Grid Inverters Used For?
Off Grid inverters are used in caravan solar systems, boat solar systems, vineyard-garden houses, farm houses, plateau houses, GSM base stations.
On Grid Inverters (Grid connected inverters)
Inverters that directly deliver the converted electricity to the grid are called ten grid inverters. On-grid inverters, that is, on-grid inverters; It is divided into three groups as central, string and micro inverters.
Central Inverter: Central inverters are used in large power plants in solar energy investments. A single Inverter is used. The power of the inverter generally starts from hundreds of kW and goes up to MW values. Central inverters manage large panel groups from a single center.
String Inverters: String inverters can be preferred either in the field or in roof-facade applications. The purpose of the string inverter is to divide the power of the plant into parts and ensure that each part produces energy independently of each other.
Micro Inverters: Micro inverters are mounted individually behind each panel. It is recommended to be preferred in roof systems where shading is too much. The production of other panels is not adversely affected by the effect of shading with its use.
What are the Differences Between Modified Sine Inverter and Full Sine Inverter?
- While modified sine inverters operate with square wavelength, full sine inverters operate with full sine wavelength.
- They both output AC power to the Inverter.
- Full sine inverters provide quality power to run motorized devices (devices with high power requirements).
Modified sine inverters are suitable for devices with lower power requirements, such as lighting. The purpose of manufacturing modified sine inverters is that they are cost effective. These explanations are valid for correct power selections.
