Over-voltage protection  : When the battery voltage is higher than the "over-voltage point", the device will automatically cut off the inverter output, the buzzle will alarm and front panel LED readings will disappear,. Until the voltage is dropped to "over-voltage recovery point", the inverter back to work.

Low-voltage protection  : When the battery voltage is lower than "low-voltage point", in order to avoid over-discharge damage to the battery, the device will automatically cut off the inverter output. In this case,  the buzzle will alarm and front panel LED readings  will disappear,. Until the voltage increases to "voltage recovery point", the inverter back to work.  The following is the voltage range of commonly used input specifications

12VDC VERSION 24VDC VERSION 36VDC VERSION 48VDC VERSION
DC input range 10V-15V 21V-30V 30V-45V 42V-60V
Low Voltage Alarm 10V±0.5VDC 19.5V-21.5V 32.9V-31.5V 43V-45V
Low Voltage Shut Down 9.5V±0.5VDC 18.5V-20.5V 29V-31V 41V-43V
Over Voltage Shut Down 15±0.5VDC 30.5V 45V 61V

 

Overload protection: If the AC output power exceeds the rated, the device will automatically cut off the inverter output, the buzzle will beep and front panel LED readings disappear. Close the front panel of the "inverter switch". To reboot, please check that the load within the allowable range, and then turn on the inverter to restore it  

Short circuit protection: If the AC output circuit short circuit, the device will automatically cut off the inverter output,  the buzzle will alarm while the front panel LED readings will disappear. Close the front panel of the "inverter switch". To reboot, please check to confirm output line normal, and then turn on the inverter to restore it 

Overheating protection:The inverter has a built-in large-area aluminum radiator and two 60mm*60mm cooling fans. If the temperature inside the pure sine wave inverter control part is too high,the cooling fans will automatically run to reduce the internal temperature

Reverse battery protection: The pure sine wave inverter device has a complete reverse battery protection features. The fuses will automatically blow inside the case to avoid damage to the battery and inverter. But still prohibited to reverse the battery!

GND protection: The inverter is equipped with the ground connection

The yellow wire on the terminal is connected to the grounding screw at the bottom of the inverter. As long as one of them is grounded, the inside of the inverter and the inverter shell can be grounded
