Rated output voltage
It indicates the rated voltage value that the inverter should be able to output within the allowable fluctuation range of the specified input DC voltage. The stability accuracy of the output rated voltage value is generally specified as follows.
In steady-state operation, the voltage fluctuation range should have a limit, for example, the deviation should not exceed ±3% or ±5% of the rated value.
Under dynamic conditions, when the load changes suddenly or there are other disturbing factors, the deviation of the output voltage should not exceed ±8% or ±10% of the rated value.
Unbalance of output voltage
Most people know that power inverters are used to convert DC power to AC power. However, few people understand the concept of voltage unbalance. A voltage imbalance occurs when the three phase voltages from the inverter output are not equal. This can lead to problems with equipment and even cause fires.
Under normal operating conditions, the three-phase voltage imbalance at the inverter output should not exceed a specified value, usually expressed as a %, such as 5% or 8%. If the voltage imbalance exceeds this value, it is considered to be a fault. There are several causes of voltage imbalance, including.
- Loose or damaged AC power cord
- Incorrect wiring
- Faulty inverter
If you suspect that your inverter is outputting a voltage imbalance that exceeds the specified value, you should contact a qualified electrician or inverter technician immediately.
Distortion of the output voltage waveform
There are many different types of power inverters on the market, each with its own specific output voltage waveform. When selecting a power inverter, you must ensure that the output voltage waveform of the inverter matches the load it is intended to power. Most inverters have a sine wave output voltage waveform, but some have a modified sine or square wave output voltage waveform. Each type of waveform has its own advantages and disadvantages, and it is important to choose the correct waveform for your application.
One thing to remember when choosing a power inverter is the maximum waveform distortion allowed. When the inverter output voltage is a sine wave, the maximum allowable waveform distortion should be specified, usually expressed as the total waveform distortion of the output voltage. This value should not exceed 5%. This is to ensure that the power inverter does not damage the load it supplies.
Therefore, when selecting a power inverter, be sure to check the output voltage waveform and the maximum waveform distortion to ensure that the inverter is compatible with the load.
Rated output frequency
It is well known that the frequency of the inverter output AC voltage should be a relatively stable value, usually 50 Hz. However, under normal operating conditions, the deviation should be within ±1%. So, what does this mean to us?
Basically, it means that the inverter is working properly and providing a stable voltage for our needs. However, if the deviation is more than ±1%, then there may be some problems with the inverter. Therefore, we need to be aware of this and keep a close eye on our inverters to make sure they are working properly.
Load Power Factor
Inverters are capable of carrying inductive or capacitive loads under certain conditions. When the load is inductive, the power factor is usually 0.7 to 0.9. If the load is capacitive, the power factor is usually 0.9. The capacity of the inverter is determined by the maximum power it can handle.
Rated Output Current
Indicates the rated output current of the inverter over the specified load power factor range. Some inverter products give the rated output capacity in VA or kVA. When the output power factor is 1, the rated capacity of the inverter is the product of the rated output voltage and the rated output current.
Rated Output Efficiency
The efficiency of an inverter is the ratio of its output power to the input power under the specified operating conditions, expressed in %. The efficiency of the inverter at rated output capacity is the full-load efficiency, while the efficiency at 10% of the rated output capacity is the low-load efficiency.
Protection
An inverter is an electrical device that converts DC power to AC power. Inverters are used in a variety of applications, from small electronic devices to large industrial applications.
One of the most important aspects of an inverter is its overvoltage protection. Overvoltage protection prevents the inverter from being damaged by excessive voltage.
Most inverters have built-in overvoltage protection. However, for those inverters that do not have such protection, it is important to have other measures in place to protect the inverter from damage.
One of these measures is to have a voltage stabilization device. This device will help regulate the voltage to a safe level and prevent the inverter from being damaged due to excessive voltage.
Another measure that can be taken is to have an overcurrent protection device. This device will help protect the inverter from damage caused by excessive current.
By taking these measures, you can help protect your inverter from damage caused by overvoltage and overcurrent.
Start-up characteristics
Inverters play an important role in connecting renewable energy sources to loads in any electrical system. The inverter must have the ability to start up at rated load and deliver the required power to the load with good dynamic performance.
Renewable energy sources are very volatile in nature and the inverter must be able to handle this fluctuation and provide stable power to the load. In addition, the inverter must be able to protect the load from voltage spikes and other surges.
The inverter must be designed to start reliably at rated load and must have good dynamic performance. The inverter should be able to deliver the required power to the load with minimal distortion.
Noise
Noise generation is a common issue in power electronics, and can be caused by various factors such astransformers, filter inductors, electromagnetic switches and fans. In order to ensure that the noise doesnot exceed acceptable levels (80dB during normal operation and 65dB for small inverters), it is important toidentify the source of the noise and take appropriate measures to mitigate it.
