Feature:

• QW series inverter adopted raw materies form IR & ST company, such as power tube, IC etc; adopted transformer in copper foil winding reduce consume compare with copper wire or aluminum  wire wiinding, directly improve inverter effective power and reduce failure rate. 

• High quality: CE & Rohs & SGS was approved.
• Adopted 2 big 7025 cooling fans, improve cooling ability, save enery and lengten the use life. 
• Voltage display: digital display
• Maximum 3000W continuous output and 6000W surge power.
• UPS（Uninterruptible Power Supply）with Charging function: When commercial power is on, inverter use commercial power; when commercial power is off, inverter will be transfer to use battery power and charging automatically, and the transfer time is less 10mS.
