An inverter is a converter that transforms direct current (DC) electricity from sources like batteries or storage batteries into fixed-frequency, constant voltage, or variable-frequency alternating current (AC) electricity, typically a 220V, 50Hz sine wave. It consists of an inverting bridge, control logic, and filtering circuits. When using an inverter, we need to know the possible faults and repair methods. The following are common faults and troubleshooting methods.
The emergence and application of frequency converter simplifies the complex control and makes the production process more convenient and fast. However, like other control devices, the frequency converter will inevitably fail in application. Frequency inverter can be powerful tool in maintaining processes by using diagnostics to solve frequency inverter performance issues and troubleshoot related processes. Fault analysis in a VFD inverter involves identifying and diagnosing any issues or malfunctions that may occur in the operation of the device. Here are some common fault analysis areas for frequency inverters.
Installing solar lights in your garden is one of the best solutions, because you will not be worried about the electrical setup, and your garden will be beautiful and fresh. When your solar garden stop working, there are some troubleshooting steps you can do yourself, and in most cases, you will succeed to solve the issue without the aid of a specialist, and here we shall discuss as follows:
Solar panels are made of crystalline silicon. Due to the characteristics of its own crystal structure, it is easy to crack, which constitutes the cause of cracking. Essentially, there are two types, one is mechanical stress and the other is thermal stress. , initially only some small cracks will appear in the cell, which is difficult to detect with the naked eye, but after a long time, it will develop into fragments, which are visible to the naked eye at this time.
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.
As wind turbine is very important and when there is troubles, it is not an easy case to deal with. Today, we are going to introduce 3 common troubleshooting of wind turbines to you. We hope that this article can help you.
With the rapid development of the solar industry, solar charge controllers have now begun to spread all over the world, from our home power generation to street lighting, and finally to our transportation solar RV. The solar charge controller has its advantages and disadvantages. The advantage is that it is fully intelligent, fully automatic, and fully humanized. The disadvantage is that it is prone to failure. Buying a high-quality solar charge controller can reduce the occurrence of failures. Inverter.com has listed several reasons for the failure for you, hoping to help you.
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).
Pure sine wave inverter applications in the long term, it is inevitable due to the combined effect of a number of internal and external factors and the emergence of certain failure, thus affecting the normal use of the device. Then, we need to find specialized service personnel to repair the fault detection. This article will introduce the pure sine wave inverter during maintenance.
The photovoltaic off-grid power generation system is mainly used to solve the basic electricity consumption problem for residents in areas without electricity or insufficient electricity. The photovoltaic off-grid power generation system is mainly constituted of the photovoltaic component, bracket, controller, power inverter, storage battery and power distribution system. Compared with the photovoltaic grid-connected system, the off-grid system has an additional controller and storage battery. In addition, the inverter directly drives the load, so the electrical system is more complicated. Since the off-grid system may be the only power source of the user and the user relies more on the system, the off-grid solar system design and operation must be more reliable.
