Overload Protection: If the total power of connected loads is bigger than the inverter’s rated limits, the inverter will automatically stop working in 20 seconds. The protection light (red) will light up; and the protection mode will be locked. Reduce the loads and switch off the inverter for half a minute, then the inverter can resume working.
Short Circuit Protection: If short circuit problem happens to the loads in process of working, inverter will automatically protect itself. The condition is same to overload protection. Please figure out and solve the problem before resume working
Overheat Protection: The inner temperature of inverter will increase in following conditions: too many loads connected, working for long time, ambience temperature is high and ventilation is poor. When the inner temperature reaches 80℃, the Warning Light will light up and inverter will stop working and lock the protection mode. We recommend you reduce the number of loads, improve the ventilation and cool down the inverter, and then resume the inverter working.
Low Voltage Protection: When the voltage of battery steps down to 10.5V, the inverter will alarm and stop working. Please switch off the inverter and charge the battery before resume working.
Over Voltage Protection: When input voltage is higher than 16V, the inverter will refuse working even if you switch it on. It will resume working only if the input voltage is lower than 15V.
Reverse Connection Protection: When input power is mistakenly connected, the inside fuse of inverter will be burnt. You’re recommended disconnect inverter and input power immediately, carefully open the inverter cover and change the proper fuse, and correct the connection between inverter and battery and then switch on the inverter again.
Although the product has the function of Reverse Connection Protection, the arc discharge still can cause big electrical sparkle which many severely damage the equipment and users.
