◤DA SERIES PURE SINE WAVE INVERTER CHARGER：
According to the output waveform, how many types of inverters are divided?
Inverters are divided into three categories according to output waveform: pure sine wave inverter charger, modified sine wave inverter charger, and square wave inverter charger.
1) Pure sine wave inverter charger is generally used for precision instruments. Although it is expensive, it outputs sine wave AC power that is the same as or even better than the power grid we use everyday, because it does not have electromagnetic pollution in the power grid.
2) The modified sine wave inverter charger is cheap. The modified sine wave is a kind of waveform between pure sine wave and square wave. There is a time interval between the positive maximum value and the negative maximum value of its output waveform.
The modified sine wave inverter charger greatly reduces the power loss of the system due to the use of special intelligent circuits and high-power field effect transistors. The soft start function is added to effectively ensure the reliability of the inverter. If the requirements for power quality are not very high, and it can meet the needs of most electrical equipment, but it still has 20% harmonic distortion, which will cause problems when operating precision equipment, and also cause high-frequency interference to communication equipment.
3) The output of square wave inverter charger is square wave AC with poor quality, and its positive maximum value and negative maximum value are almost generated at the same time, which will cause severe unstable impact on the load and inverter itself.
Xindun Power provides a DA pure sine wave inverter charger with moderate price and high quality, which can ensure the safe and stable operation of equipment in your home, office, factory and other places.
◤DA PURE SINE WAVE INVERTER CHARGER WORKING MODE：
In the system with PV off-grid energy storage, the working modes of the pure sine wave inverter charger can be divided into three types. They are: Mains power priority, battery priority and PV priority. This is determined by their application scenarios and requirements, so they set different modes of pure sine wave inverter charger according to different requirements. Maximize the work of PV.
Working mode of pure sine wave inverter charger:
1）PV priority mode: refers to the priority of PV power supply to the load. When the PV power is less than the load power, the energy storage battery and PV power supply to the load together. His application scenarios can be in areas without electricity, including areas where the market electricity price is not high but there will be frequent blackouts.
2）Mains power priority mode: Mains power priority is also called grid priority mode. Its working mode is whether there is PV power or lithium battery power. As long as the mains power is detected, the mains power will supply power to the load. When the mains power failure is detected, it will automatically switch to PV cells to supply power to the load. His application scenarios include areas with stable voltage, low price but short power supply time.
3）Battery priority mode: PV gives priority to power supply to the load. When the PV power is insufficient, the battery gives priority to power supply to the load. His application scenario is in areas with occasional power failure or when the voltage is unstable.
◤24V PURE SINE WAVE INVERTER CHARGER OR 12V PURE SINE WAVE INVERTER CHARGER?
12v pure sine wave inverter charger saves more power than 24v pure sine wave inverter charger.
The working principle of the 12v 24v pure sine wave inverter charger is to convert the DC power of the battery into AC power, and then boost it to 110V/120V/220V with a transformer.
The conversion from direct current to alternating current is accomplished by using transistors. Even if the tube is fully connected, it also has a voltage drop (called saturation voltage drop). The saturation voltage drop is consumed on the transistor.
For example, if the saturation voltage drop is 1V, then the efficiency loss caused by only this problem:
12v pure sine wave inverter charger, loss of battery power supply saturation voltage drop:
24v pure sine wave inverter charger, loss of battery power supply saturation voltage drop:
What is the difference between 12v pure sine wave inverter charger and 24v pure sine wave inverter charger?
The difference between the 12v pure sine wave inverter charger and the 24v pure sine wave inverter charger is very big. The main difference is that the voltage used by the pure sine wave inverter charger is different, because the 12v pure sine wave inverter charger can convert the DC 12V to the required AC voltage as long as the 12V battery is used, so the 24v pure sine wave inverter charger must use the 24V DC battery to connect to the pure sine wave inverter charger to convert to the required inverter voltage, so the voltage of the pure sine wave inverter charger is different, It selects different DC voltage.
The batteries used in 12v pure sine wave inverter charger are mostly 12v lead-acid batteries. Of course, lithium batteries are also used, but they are rarely used. The battery used by the 24v pure sine wave inverter charger is mostly lithium battery, because there is a single 24V battery, which is small in size and light in weight. If you want to use lead-acid batteries, you can only use two batteries in series, which are also large and several times heavier.
◤12V 24V 48V PURE SINE WAVE INVERTER CHARGER：
Which is the better 12v 24v 48v pure sine wave inverter charger? Xindun Power pure sine wave inverter charger manufacturer will explain how to choose the voltage of the pure sine wave inverter charger.
There are differences between 12v 24v 48v pure sine wave inverter charger. When selecting your own power supply specification, you should first determine your place of use. How large the specification is suitable for your place. It is unnecessary to exceed or reduce it.
The general power of home and car vehicle pure sine wave inverter charger is not more than 5000W. Most of the inverters sold on the market are 12v pure sine wave inverter charger and 24v pure sine wave inverter charger, and 36, 48, 60 and other pure sine wave inverter charger with high input voltage. Inverters with high input voltage are suitable for connecting electric bicycle batteries or other special applications. After comparison and measurement, no matter 12v pure sine wave inverter charger or 24v pure sine wave inverter charger, its output current and loss are similar under the same power, which is relatively small power pure sine wave inverter charger (within 2000W).
However, many high-power inverters choose 24v pure sine wave inverter charger, because 24V batteries with the same capacity provide more output current than 12V batteries.
So it is enough to choose 12v 24V pure sine wave inverter charger for low-power electrical appliances.
The 48V pure sine wave inverter charger (6000W or 8000W inverter) is of high input voltage, which is suitable for other special applications. General applications: communication equipment, railway system, power station and other large conversion devices.
Because the current of 12V pure sine wave inverter charger circuit is much larger than that of 24V 48V pure sine wave inverter charger circuits. The current is large, the damage is large, and the heat generation is more serious. So Xindun Power is very strict in its design for the high-power 48v pure sine wave inverter charger. For the heat dissipation, we have designed a temperature-controlled fan. Advantages: reduce noise, improve efficiency and extend fan life.
