A pure sine wave inverter is important in different scenes, the output waveform of the pure sine wave inverter is like a sine waveform(below) and is basically the same as the alternating current waveform of the mains grid, the distortion is very low.

Compared with the modified inverter, the pure sine wave inverter has little interference to radio, communication equipment, and precision equipment, low noise, strong load adaptability, can meet the application of all AC loads, and the whole machine has high efficiency.

Actually, an excellent pure sine wave inverter even provides a better alternating current than the mains grid, like the FCHAO inverter. There is no electromagnetic pollution in the power grid. In short, it has a wide range of applications, strong load capacity, excellent stability, and can provide the same AC power as ordinary households. In the case of satisfying power, it can drive almost any kind of electrical appliance.

Feature

High Stability: Because the system has complete protection functions such as over-voltage, under-voltage, overload, overheating, short circuit, reverse connection, etc., the stability of the system is ensured.

Liquid Crystal Display: an ordinary inverter has a liquid crystal display battery voltage and output voltage and status parameters. Here, the FCHAO inverter has two displays for customers. FCHAO liquid crystal display battery power ratio, battery voltage, AC voltage, AC power, temperature, and cooling fan. FCHAO light-emitting display battery power ratio, batter voltage, AC voltage, and AC power all can be turned automatic or manual.

Efficient Conversion: The inverter has high inverter efficiency and low no-load loss. FCHAO inverters of different models and specifications are equipped with low no-load loss.

Digital Intelligent Control: The core device is controlled by a powerful single-chip microcomputer, which makes the peripheral circuit structure simple, and the control method and control strategy are flexible and powerful, thus ensuring excellent performance and stability.

Function

Over–voltage Protection Function: When the battery voltage is greater than the “over-voltage point”, the device will automatically cut off the inverter output, and the buzzer will cycle 4 times to give an alarm. When the voltage drops to the “over-voltage recovery point”, the inverter resumes work.

Under-voltage Protection Function: When the battery voltage is lower than the “under-voltage point”, in order to avoid damage to the battery due to over-discharge, the device will automatically cut off the inverter output, and the buzzer will ring 3 times to give an alarm. When the voltage rises to the “under-voltage recovery point”, the inverter resumes work.

Overload Protection Function: FCHAO inverter can be divided into three situations, if the overload is greater than 110%～130%, the AC output will be turned off continuously for 15 seconds; if the overload is greater than 130%～150%, the AC output will be turned off for 5 seconds; if the overload is greater than 150%, the AC output will be turned off for 2 seconds Output; three situations require a reset switch to recover.

Short Circuit Protection Function: turn off within 2 seconds, and restore after resetting the switch.

Over-temperature Protection Function: If the temperature of the internal control part of the chassis is too high, the device will automatically cut off the inverter output, and at the same time, the buzzer will ring 5 times to give an alarm. After the temperature returns to the normal value, the inverter output is restored.

Besides, when the output power is more than 50% or the temperature is higher than 50℃, the inverter cooling fan of  FCHAO’s model KSC and PSC will turn on. When the output power is lower than 35% or the temperature is cooler than 45℃, the cooling fan will turn off.

Battery Reverse Connection Protection Function: The equipment has a perfect battery reverse connection protection function. If the positive and negative polarity of the battery is reversed, the fuse in the chassis will be automatically blown to avoid damage to the battery and equipment. However, it is still strictly forbidden to reverse the battery connection.
