Fully Safety Protections
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
