What is the difference between an inverter power supply or a solar inverter? Which is better?

Solar inverter power supply, also known as solar inverter, is a DC/AC converter that converts the DC power supply of the battery pack into an AC power supply with stable output voltage and frequency. It generally refers to a device that converts low-voltage direct current into high-voltage (or low-voltage) alternating current. It can use a battery as a power source to output alternating current. Specifically, for example, a 12V battery cannot supply power for ordinary lights, computers, TVs, etc., but the battery is converted into ordinary 220V AC through a solar inverter and then connected to these appliances. They can work normally.
Generally, the inverter power supply comes with its own battery, and the UPS power supply sold by the computer city is such a thing, but the battery itself is small and can only be used for the computer to work for a few minutes to ten minutes, mainly for the sudden power outage. , which continues to power the computer, giving you time to save unsaved files and time to shut down gracefully.
use
It is used in environments without AC power to provide power to AC equipment. Its output power varies from tens of watts to hundreds of kilowatts; the input DC voltage varies from a few volts to hundreds of volts.
It is mainly used in the following places:
1. In cars, boats and planes, together with the DC power supply on the vehicle, to provide power for AC appliances;
2. In places without power supply, together with other power generation equipment (solar energy, wind energy, water energy and various fuel generators), to provide users with AC power
3. As communication, power system Uninterrupted Power Supply
4. As a fire emergency power supply Emergent Power Supply
5. Utilize portable power supply, such as AC power supply when provided.

The solar inverter is a DC to AC transformer, which is actually a voltage transmission process with the converter.
principle:
The converter converts the AC voltage of the power grid into a stable 12V DC output, and the inverter converts the 12V DC voltage output by the Adapter into high-frequency high-voltage AC; both parts also use the more widely used pulse width. modulation (PWW) technology. Its core part is a PWM integrated controller, the Adapter uses the UC3842, and the inverter uses the TL5001 chip. The working voltage range of TL5001 is 3.6~40V. It is equipped with an error amplifier, a regulator, an oscillator, a PWM generator with dead zone control, a low-voltage protection circuit and a short-circuit protection circuit.
Input interface part: The input part has 3 signals, 12V DC input VIN, work enable voltage ENB and Panel current control signal DIM. VIN is provided by Adapter, ENB voltage is provided by MCU on the main board, its value is 0 or 3V, when ENB=0, the transmitter does not work, and when ENB=3V, the transmitter is in normal working state; while the DIM voltage It is provided by the main board, and its variation range is between 0 ~ 5V. If different DIM values ​​are sent to the feedback terminal of the PWM controller, the current provided by the transmitter to the load will also be different. The smaller the DIM value, the output of the transmitter. the greater the current.
Voltage startup circuit: When ENB is high, it outputs high voltage to light the backlight lamp of the Pane.
PWM controller: It consists of the following functions: internal reference voltage, error amplifier, oscillator and PWM. Overvoltage protection, undervoltage protection, short circuit protection, and output transistor.
DC conversion: A voltage conversion circuit is composed of a MOS switch tube and an energy storage inductor. The input pulse is amplified by a push-pull amplifier and then drives the MOS tube to perform switching action, so that the DC voltage charges and discharges the inductor, so that the other end of the inductor can get AC Voltage.
LC oscillation and output circuit: ensure the 1600V voltage required for lamp start, and reduce the voltage to 800V after the lamp is started.
Output voltage feedback: When the load is working, the sampling voltage is fed back to stabilize the inverter voltage output.

Application field
1. The 220V power obtained by the transmitter on the car is 220V 50HZ, the high-end point is a sine wave, and the cheap one is generally a square wave.
The sine wave type is the same as the electricity used in the socket, and the square wave type can also be used, but if you use a fan and other equipment with a motor, there will be some noise. The reason why the square wave is used is because The cost of this modulation method is relatively low. Generally speaking, the maximum power of the inverter in the car is no more than 500 watts, and the air conditioner is generally more than 700 watts. Moreover, you really want to put the household air conditioner on the car? The air conditioner in the car, including those large buses, They all let the engine directly drive the compressor, not electricity, if there is an additional electrical conversion process in the middle. The loss is even greater. And it is not easy to install, it is better to use the car air conditioner.
2. Connect notebooks, TVs, CD players and other things, as long as they are used at their rated power, there is no problem, but it should be noted that they are connected to the car battery, although they are generally 11V, they will automatically protect and power off. To avoid the voltage being too low, the car cannot be started, but it is still not suitable for use when the engine is not running, so if the load is relatively large, it is recommended to start the study. If it's charging the phone, it's fine.
3. On the electric vehicle, there is a module called DC-DC, which is also called a DC converter. This module has an input of 48V and an output of 12V, so you only need to buy a car inverter with a 12V input and you can use it. Of course, it is better if Ruoer can buy an inverter with 48V input, but it is estimated that it is difficult to buy. Moreover, this module can generally only provide 5A current, but at most 10A, and the lights are also used, so it is easy to overload, It is suggested that if you can, buy an extra DC converter. This converter is specially designed to supply power to your transmitter. If the DC converter can only provide 5A, then the input of the transmitter should be less than 5A, otherwise it may damage the transmitter. Modules, of course, some DC converters have a large current. If there is no place to repair the car, you can go to some electrical stores or ask them to repair them and give you a high current, or multiple DC converters can be connected in parallel, in short , don't overload him.
4 There is a vvvf traction transmitter on the urban rail vehicle, which is used for frequency conversion and voltage conversion, and converts high voltage (usually DC750V or DC1500V) into a three-phase power supply with adjustable frequency and voltage during train traction. The traction motor is used in the system. When moving, the three-phase electric energy generated by the inertia of the train to drive the traction motor to rotate can be converted into direct current and fed back to the grid or consumed through the energy star consumption module.

The main applications of solar inverters in the field of communication are:
Provides AC auxiliary power for DC power.
Some maintenance tools require AC power, and DC power cannot provide AC power, which can be provided by an inverter.
Provide DC-AC conversion function for photovoltaic grid-connected power system.
The direct current generated by the solar system is converted into alternating current and fed into the grid.
