Everything You Need to Know About Power Inverter Protections

Power surges, blackouts and other unexpected events can put your inverter, the equipment it powers and the people around it at risk. Components or cables could overheat, melt and even cause a fire.

That's why inverters are equipped with various protection mechanisms designed to monitor various levels and shut down the inverter if necessary.

1. Undervoltage Protection(UVP)

The voltage will decrease or lost sharply in a short time due to short circuit or other breakdowns that can burn your devices. A DC12V power inverter that is built-in low voltage protection can send out a sound and light alarm signal when the input voltage is 9.5V~11V, that means the voltage of battery is too low and you need to power it up.

2. Overvoltage Protection(OVP)

When the input DC power becomes too higher than its compatible power rate, the power inverter will send out sound and light alarm, and also cut off power to protect your devices from damage.

3.Short Circuit Protection(SCP)

When short circuit occurs, the input current will flow from positive pole to negative pole without passing by any plugged device. In that case, the current becomes too high to bear for the batteries, thus causing damages to equipment or even fire because of overheating. Short circuit protection can cut of power timely and avoid the above problems.

4. Over-Current Protection(OCP)

Electronic devices have rated current and devices are easy to get burned if the input current is higher than its rated current. Power inverter with overcurrent protection will automatically cut off the power to protect devices. Some inverters have overcurrent protected USB ports, when overcurrent occurs, the USB board can be well protected against burning.

5. Over-Temperature Protection(OTP)

Power inverters are easy to get heated when keeping working for a long-time or work under a high temperature environment. The overheating protection will remind you timely with a flashlight and cut off power at the same time to ensure not cause fire accidents or break your devices.

6. Overpower Protection (OPP)

Power inverters are designed with multiple charging stations including AC outlets and USB ports. If you charge devices with a higher overall power than its rated power, it will stop providing power for your devices. But with overloading protection, your devices won’t be damaged.

7. Reverse Polarity Protection(RCP)

The pure sine wave inverter device has a complete reverse battery protection features such as battery polarity is reversed. The fuse will automatically fuse inside the chassis to avoid damage to the battery and the device. But still forbidden reverse battery!
