1.Using Mitsubishi’s sixth-generation high-efficiency IPM intelligent module, with high efficiency and stability, powerful protection functions, short-circuit, overload, and over-temperature protection are safer and more reliable, and the service life can be more than 15 years;

2. Intelligent, modular design, simple structure and easy maintenance;

3. Adjust the use mode of the system according to the product configuration conditions: inverter priority or mains bypass priority can be set arbitrarily;

4. The dual-mode start selection function, through the LCD setting, you can set two modes of step-down start and frequency conversion start. In this way, the power of the inverter can be fully utilized, and there is no need to expand the capacity of the inverter when the motor is equipped with inductive load, which saves the user's cost;

5. The output frequency can be set by yourself. For example, if you want to control the motor speed to 30HZ, the inverter will output 30HZ. This function is very convenient for customers to use in different load types;

6. The input DC voltage range can be set, such as over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point can be set through the LCD screen. This function is convenient to increase or decrease the battery, and the photovoltaic module can be used flexibly;

7. Output pure sine wave, it has a transient response of less than 50MS, small waveform distortion, high inverter efficiency and stable output voltage;

8. Built-in power frequency isolation transformer, strong impact resistance, can be equipped with strong impact equipment such as motors, motors, air conditioners, etc. At the same time, the DC bus is completely isolated from the AC bus, avoiding the interference between AC and DC;

9. LCD liquid crystal display, can display input DC voltage, output frequency, phase voltage, phase current, mains bypass voltage, output power KWH, time, temperature, fault display;

10. Using SVPWM space vector algorithm, high conversion efficiency, high instant power and low no-load loss conversion efficiency can reach more than 93%;

11. The wide voltage input can be customized according to customer requirements. The input voltage range is from 100-400V, 200-500V, 300V-600V or 450-800VDC, suitable for solar/wind energy systems without backup batteries, and the DC input is directly connected to solar panels/wind power Machine, online switching time is 0 seconds;

12. This product has passed the European CE (EMC and LVD) certification and the Australian Energy Network CEC certification;
