• LED Display
• Optional LCD Display (pls. ask)
• Microprocessor-based digital control
• Boost and buck AVR for voltage stabilization
• Auto sensing frequency
• Wide input voltage range
• Power-on self testing
• Cold start
• Auto restart when mains power is restored
• Auto track mains phase to ensure that inverter output voltage
has same phase with utility voltage, reducing transfer time
and peak surge
