What is the difference between the Battery/Surge outlets and the Surge outlets?

Many CyberPower UPS units have two sets of outlets. One set is labeled “Battery/Surge” and one set is labeled “Surge”. The outlets labeled “Battery/Surge” are the outlets that will receive battery power during a power failure. You should plug your computer and monitor into these outlets and any externally powered critical data storage device.

Why does my inverter periodically beep twice?

This is due to overloading or underpowering. Overloading is caused by an excessive load and can be resolved by either upgrading to larger power inverter or by reducing the load of the attached equipment. If the device is underpowered, connect it to power source that is outputting greater than 11 volts. Most often, users simply need to start their vehicle and recharge the battery.
