Superior performance 

◆ using the most advanced fifth generation IGBT technology to enhance the efficiency of the inverter, the inverter's temperature lower, higher reliability, while significantly reducing the harmonic content of the output voltage (<3%), distortion of the output of the inverter has a higher reliability and stability, while improving the overall efficiency of the inverter (> 97%); 

◆ Flexible AC input voltage range of settings, depending on the supply demand environment AC power quality and load through the operator panel 

Set the AC input voltage and frequency range. 

◆ inverter fully meet from 0-100% load jump, without having to switch to the bypass, and ensure that the output is stable and reliable; 

◆ instantaneous feedback control using a variety of control methods and RMS, to achieve a high dynamic regulation, reduce the output voltage distortion; 

◆ using the new vortex fan, excellent thermal performance, speed and energy saving;

Comprehensive and reliable protection measures 

◆ with power self-diagnosis function to avoid the risk of failure due to the inverter is likely to cause hazards; 

◆ with output overload / short circuit protection; inverter over-temperature protection; battery voltage warning protection; electric multiple fuses, circuit breaker protection and other protection functions, which greatly ensure the stability and reliability of the system operation.

Human information processing technology 

◆ Goodwill in English and optional HMI touch screen design, intuitive operation status flowchart intelligent touch-screen design icon, makes machine communication distance; 

◆ rich inverter operation data, historical event logging, and multi-level fault code display, makes the human information processing; 

◆ through RS232 interface, with intelligent monitoring software can be used with a variety of PC instant messaging parameters and working conditions, the inverter system at a glance display on the PC communication interface; 

◆ standard MODBUS protocol RS485 interface and 14 road dry node interface, especially for industrial control field; 

◆ The external SNMP adapter, the system has a direct Internet access, provide real-time data and power inverters messagesthrough a variety of network management platform for communication, management, system instantly become a network.
