With the rapid development of renewable energy sources, solar photovoltaic (PV) power systems have become a popular choice in the clean energy sector. The on-grid inverter is a crucial component in solar power systems, playing a key role in converting solar power into alternating current (AC) that can be used in power networks. The inverter store will provide an in-depth look at how grid-connected inverters work, their application areas, and technology trends to help readers better understand this technological component that plays an important role in the clean energy transition.

When it comes to solar energy systems, inverters play a crucial role in converting the direct current (DC) electricity generated by solar panels into the alternating current (AC) electricity used in homes and businesses. Two common types of inverters used in photovoltaic (PV) systems are microinverters and string inverters. In this comprehensive blog post, we will delve into the differences between microinverters and string inverters to help you understand which one may be more suitable for your solar installation.

With the growing global demand for energy and increasing environmental concerns, renewable energy has emerged as an important option to address these challenges. The development of renewable energy resources such as solar and wind power not only reduces dependence on finite fossil fuels but also helps to reduce greenhouse gas emissions and mitigate climate change. In the field of renewable energy, solar power systems and wind power systems are the two most common forms. However, inverters are required to convert the electrical output of these systems into electricity that can be used for domestic, industrial, and commercial purposes. With the rapid development and popularization of renewable energy sources, micro inverters have become an integral part of modern energy systems. These small but powerful devices play a key role in converting renewable energy sources such as solar and wind into electricity.

Solar energy has made great progress in the past decade. With the decline of technology price, the demand for solar PV is also increasing. There are many reasons why people install solar PV, but most people see it as a way to help reduce electricity bills and carbon footprints. Once you have installed solar panels, it is important to understand how to make the most of them.

Solar inverter is an important part of solar power generation system. It converts all direct current generated by solar panels into alternating current, which can supply power to anything that needs power. Without inverters, the power collected by solar panels would have nowhere to go. Not only that, the inverter is also the brain of the solar system.

Batteries life span is defined as the time period they are useful before they can no longer valid to be recharged or even hold a charge. We usually measure the batteries life span in terms of cycles or certain time limit in years or days or hours. Battery cycle refers to the number of times they can be discharge and re-charged again.

We have to well know and understand the amount of energy that batteries will be able to store, so we can choose the solar panels that will be able to charge such batteries in a suitable rate, based on our usage pattern, or in other word, based on our load pattern. In this article, Inverter.com will introduce how many batteries are needed in a solar system.

The electricity produced by PV modules is direct current, which can be converted into alternating current by inverters and then used, or all of it can be delivered to the public grid. From another point of view, the electricity generated by the PV power generation system can be used immediately, or the electricity can be stored in storage devices such as batteries and released for use at any time as needed.

With the increasing global demand for renewable energy, solar energy is increasingly being used as a clean and renewable form of energy. In a solar power system, the inverter, as a key device, undertakes the important task of converting the direct current (DC) power generated by solar panels into the alternating current (AC) power required for domestic, industrial, and commercial electricity consumption. In recent years, hybrid solar inverter, as a new inverter technology, has attracted much attention due to its unique advantages. Inverter Online Shop will introduce the basics of hybrid solar inverter in detail below, including its introduction, main features, significant advantages, and application scenarios.

As the core of the power generation system, the solar inverter's life directly affects the normal operation of an entire power station. The life of the solar inverter has become a special concern for everyone. So what are the factors that directly affect the life of solar inverters? Let's take a deep dive into the factors that directly affect the life of a solar inverter in terms of component life, design and installation overall.

A grid tie inverter (GTI for short) also called on-grid inverter, which 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 pv inverters are commonly used in applications where some DC voltage sources (such as solar panels or small wind turbines) are connected to the grid. This article delves into the basics, working principle, and function of on grid inverters, highlighting their significance in modern solar power systems.

Low insulation resistance Unplug all the strings on the input side of the solar inverter, and then connect them one by one. Use the function of the solar inverter to start up to detect the insulation resistance to detect the faulty strings. After finding the faulty strings, check whether the DC connectors are flooded with short-circuit brackets. Or burn the short-circuit bracket, and also check whether the component itself has black spots on the edge to burn, causing the component to leak to the ground grid through the frame.

The solar power inverter is the core equipment of the photovoltaic system. Its main function is to convert the direct current from the photovoltaic modules into alternating current that meets the requirements of the grid. As a power electronic device, inverters, like all electronic products, face challenges brought about by temperature. In all electronic product failure cases, up to 55% of them are caused by temperature. The electronic components inside the inverter are also very sensitive to temperature.

As the core equipment of the photovoltaic power generation system, the inverter is used to convert the variable DC voltage generated by the photovoltaic modules into the alternating current of the mains frequency, which is one of the important system balances in the photovoltaic array system. At present, the common inverters on the market are mainly string inverters and micro inverters. Now, let us compare and analyze between them.

In the photovoltaic system, the electric energy generated by the solar cell is first stored in the battery, and then converted into 220V or 380V alternating current through the inverter. However, the battery is affected by its own charge and discharge, and its output voltage varies widely. For example, for a nominal 12V battery, its voltage value can vary between 10.8 and 14.4V (exceeding this range may cause damage to the battery).

The grid tied inverter is generally used in the system of large-scale photovoltaic power stations. Many parallel photovoltaic strings are connected to the DC input end of the same centralized inverter. Generally, 3 phase IGBT power modules with high power are used, and the power is relatively high. Small uses field effect transistors, while using a DSP conversion controller to improve the quality of the power produced, making it very close to a sine wave current.

Solar inverter is the brain of the photovoltaic power generation system. In the process of photovoltaic power generation, the power generated by the photovoltaic array is DC power, but many loads require AC power. The DC power supply system has great limitations— it is inconvenient to convert voltage, and the load application range is also limited. Except for special electricity loads, inverters are required to convert DC power into AC power. The solar inverter is the heart of the photovoltaic power generation system, which converts the direct current generated by the photovoltaic modules into alternating current, and transmits it to the local load or grid. It is a power electronic device with protection functions.

The solar AC power generation system is composed of solar panels, charge controllers, inverters and batteries; the solar DC power generation system does not include inverters. The process of converting AC power into DC power is called rectification, the circuit that completes the rectification function is called a rectifier circuit, and the device that realizes the rectification process is called a rectifier device or rectifier. Correspondingly, the process of converting DC power into AC power is called inverter, the circuit that completes the inverter function is called inverter circuit, and the device that realizes the inverter process is called inverter equipment or inverter.

Inverter inductor is generally composed of skeleton, winding, magnetic core or iron core, shielding cover, packaging material, etc. It is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but with only one winding. The biggest feature of the inductor is that the current cannot be changed suddenly, but can only gradually become larger or smaller.

The solar inverter is one of the most important electronic components in the entire photovoltaic power generation system, but the wrong installation of the solar inverter will result in a decrease in the service life of the solar inverter. Then, the next step is to introduce the installation and precautions of the solar inverter for you.
