The output power of solar photovoltaic system is generally difficult to reach the nominal power of the module, because the power of the module is tested under very good weather conditions and the temperature of the module is relatively low. Normal weather is not able to achieve this condition, photovoltaic modules may not all receive solar energy, because the photovoltaic system has losses. In this article, Home Power Inverter will tell you more.
Photovoltaic inverter is an important equipment in the photovoltaic system, the main role is to convert the direct current emitted by the photovoltaic module into alternating current. In addition, the inverter is also responsible for the detection of components, power grid, cable running state, and external communication and other important functions. The core use of IGBT protection technology in photovoltaic inverter is reflected in four aspects. In the following, Inverter.com will introduce to you.
Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy, uses special materials such as crystalline silicon plates, inverters and other electronic components, and is connected to the power grid and transmits electricity to the power grid. Photovoltaic power station in the role of the inverter, an unattended can fully automatic operation of the photovoltaic inverter how intelligent? Today we're going to sort it out.
Actually there are different batteries types we can use in our solar system with different prices, usage and benefits, that is why we should study well to select the best type for our system conditions. And here is a list for the existing different types in the market: lithium ion battery, lead acid battery and gel battery. In this article, we will talk about these batteries.
Sine wave inverter is an electric energy conversion device that converts direct current into alternating current. It completes the inverter task by conducting and turning off power semiconductor devices according to specific rules. With the rapid development of power electronics technology and the improvement of inverter control performance requirements in various industries, sine wave inverter has also been rapidly developed. In this article, we mainly talk about the development direction of sine wave inverter.
Modified sine wave inverters are a cost effective choice to run appliances and equipment that is less sensitive to power fluctuations, such as lights and some tools. Modified sine wave inverters simulate AC power inverted from DC batteries.
Sine Wave Inverter vs UPS
Saturday, February 27, 2021
An inverter is a device composed of inverter device and component, which is directly different from a transformer. In other words, the inverter can realize DC input and then output AC. The working principle is similar to that of a switching power supply, but the oscillation frequency is within a certain range. For example, if the frequency is 50Hz, the output will be AC 50Hz. An inverter is a device that its frequency can be changed. UPS (Uninterruptible Power System/Uninterruptible Power Supply) is system equipment that connects batteries (mostly lead-acid maintenance-free batteries) with the host, and converts DC power into mains power through module circuits such as the host inverter. It provides uninterrupted power, and is mainly used to some equipment that requires high power supply stability.
Inductor heating is one of the common faults in the use of sine wave inverters. There are two problems resulting to inductor heating: excessive loss on the inductor and poor heat dissipation conditions. The best way to solve the serious problem of heating is to start from the perspective of loss (inductance loss and magnetic core loss).
Inverter is a device that can convert DC (direct current, such as storage battery) into AC (alternating current/mains), which is widely used in air conditioners, computers, lighting and other electrical appliances. Especially on traveling or working, inverter can generate alternating current by being connected with batteries, so as to supply power for the instruments or electrical appliances requiring alternating current for use.
It is very easy to change alternating current (AC) into direct current (DC), and with only a diode, the simplest rectifier circuit can be formed. However, it is not that simple to change direct current to alternating current. The magnitude and direction of alternating current will change periodically over time. The mains power we use shows regular changes of sine function.
A sine wave inverter is a kind of common inverter. Sine wave inverter is a power electronic device that can convert DC (direct current) electric energy (such as power batteries, storage batteries) into AC (alternating current). The sine wave inverter outputs pure sine wave current, it is compared with a modified wave inverter. Inverter and AC-DC converter are opposite processes. AC-DC converters or power adapters rectify will convert current into direct current, while inverters will have the opposite effect. So it is get the name.
As we all know, there are two kinds of electricity: one is direct current (DC), such as electricity from batteries and mobile phone chargers, and its waveform is a straight line; the other is alternating current (AC), which is 220V/110V for household use. The alternate means that its amplitude is periodic, with positive and negative changes. Sine wave is like a wave, rising and falling. Generally, the waveform of alternating current changes according to a sine function, so it is called a sine wave. The function of the sine wave inverter is to convert direct current (linear) into alternating current (sine wave).
Most of the PV inverters on the present market are generally in the IP65 protection level, with a certain degree of wind, dust and water resistance. However, in the summer, the ambient temperature is high, and various components in the inverter are prone to high temperatures during operation, resulting in a decrease in power generation efficiency and even affecting the service life of the components. Therefore, the inverter in some photovoltaic systems is installed with a sunshade to reduce the temperature of the equipment. In addition, the installation environment of the inverter should be well shaded and ventilated to ensure the convection of the air and also increase the power generation capacity of the power station
