Supply of solar off grid inverter 400KW power frequency off grid pure sine wave high-power inverter power supply with sufficient power

Performance characteristics:

1. Adopting the sixth generation IPM intelligent module from Mitsubishi, Japan,Good performance and stabilityIt has powerful protection functions, making short circuit, overload, and over temperature protection safer and more reliable, with a service life of over 15 years;

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

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

4. Dual mode start selection function, which can be set in two ways: voltage reduction start and frequency conversion start through LCD settings. This can fully utilize the power of the inverter, eliminating the need to expand the capacity of the inverter when carrying motors or inductive loads, saving users costs;

5. The output frequency can be set by oneself, 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 with different load types;

6. The input DC voltage range can be set, such as overvoltage point, undervoltage point, overvoltage recovery point, and undervoltage recovery point, all of which can be set through the LCD screen. This function facilitates the addition or reduction of batteries, and the flexible use of photovoltaic modules;

7. Output pure sine wave, which has a good transient response less than 50MS, small waveform distortion, and inversionGood efficiencyStable output voltage;

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

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

10. Adopting the SVPWM space vector algorithm, the high conversion efficiency, high instantaneous power, and low no-load loss conversion efficiency can reach over 93%;

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

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

Optional configuration:

RS485 communication monitoring system AC bypass input complementary/charging function
