Introduction 

1.1 Brief Introduction: 

This product is a pure sine wave inverter which can con

vert 12/24/48Vdc to 110/230V

ac 50/60Hz 

based on full digital and intelligent design. It features high reliability, high efficiency,  full 
protection functions, easy installation and operation. The inverter can be applied in many fields, 
such as household appliances, electric tools and  industrial devices etc, especially for solar 
photovoltaic power system. 

1.2 Features: 

 

LCD display for battery capacity, battery voltage, AC voltage, AC power 

 

Complete isolation-type inverter technology 

 

Continuous operation at full power 

 

Wide DC input voltage range   

 

Wide working temperature range   

 

Low output harmonic distortion(

THD≤3%

 

Adoption of advanced SPWM technology, pure sine wave output 

 

Extensive protections:  Under/over input voltage,  Short-circuit,  Overload,  Reverse polarity, 
Over-temperature, and inverter’s inner fault identification protections. 

1.3 Inverter Operation: 

Connect the input and output terminals accurately. Turn on the power using the ON/OFF switch 
on the front panel. In order to avoid the protections resulted from the surge power, please turn on 
AC loads one by one after the output of the inverter is normal. Please check it as below:   

 

Ensure that the ON/OFF switch on the Inverter is in the OFF position. If the power source is 
a DC power supply, switch it OFF as well.
