When using LED lighting, please turn on the corresponding button.
Rear panel description
When using the AC output, please turn on the AC switch first, confirm that the AC LED indicator on the panel is displayed as a green light, and then insert the electrical appliance into the AC output port. Do not use when turning on the AC output switch and the LED indicator on the panel is red.
When using the UPS function, please first insert the input AC line into the AC input socket, then insert the AC line into the mains electricity, the input indicator on the panel is green, and the charge indicator light is on, indicating that it can be used normally. When the AC button is turned on, the AC output indicator is green, and then the electrical appliance can be plugged into the AC output socket. Then you can use the UPS function.
When using solar power to charge the product, the voltage should not exceed 18V, more than will damage the machine, when the solar panel is connected to charge, the corresponding indicator light on the panel is bright, if not bright, please check not to connect back or the solar panel face the sun at the wrong angle (keep at 30 degrees angle).
When the electricity is charged to the product, the charging indicator light on the panel during the charging process is red and green when it is completely full, and when the electricity quantity is shown to be 100, the actual battery has more than 90% capacity and can be used. do not have to wait until the charging indicator lights are completely green.
When using a car-mounted cigarette lighter to charge the product, the indicator light corresponding to the solar charging port will be lit and can be used when the electricity quantity is shown to be 100. This product only supports charging on a 12V car.
When the power of the appliance exceeds the power that the product itself can carry, the machine enters the protective state, disconnects the load, and restarts the machine.
When the high temperature weather, the product in the process of use, may be overheated into the protection, please put the machine in a cool place to use.
