If your solar inverter has a problem, resetting it using the inverter reset button can often resolve the issue. It is a helpful troubleshooting step as it ensures the efficient operation of your solar power setup. In this guide, we will explore how to reset inverter faults to bring the system back to its best working condition.

Why Reset an Inverter?

If you encounter issues with your power inverter, resetting is one of the basic troubleshooting options. It restores the inverter to its default settings, which can solve issues like overload, output faults, under-voltage, and power failure. Moreover, regular inspection and resetting of the inverter helps safeguard the battery from factors like excessive discharge and ensures long-term performance.

How to Reset Inverter Fault?

A solar inverter is a very crucial device for your solar power system. In simple terms, it acts like a translator that converts the energy generated by solar panels (DC) into the type of electricity (AC) that powers your home appliances. However, just like any other device, an inverter may face some problems, leading to the necessity of resetting it.

So, how to reset inverter fault? There are two methods, you can either do a soft reset or a hard reset.

1. Soft Reset

It is done through an application or computer software that is linked to the inverter. You can look for the inverter reset option in the system settings.

For a better understanding, the steps for a soft reset are listed below:

Step 1: Open the inverter software or app on your computer.

Step 2: Find and access the reset option in the system settings and activate it. Make sure that the inverter is attached to the supply power and your computer.

Step 3: Click on the inverter reset button under Reset. So, the inverter will restart, and all settings and user data will get cleared.

Step 4: After a few minutes, automatically the device will power off and then will restart, fully ready to resume its functioning.

2. Hard Reset

On the contrary, the hard reset process involves a series of steps. Here is the guide to how to reset the inverter fault by performing a hard reset on the inverter.

Step 1: Power off the inverter by flipping its switch, which is mostly available in the compact box on an outside wall.

Step 2: Turn off the AC disconnect, placed on the side or front of the inverter.

Step 3: Turn off the DC disconnect. It is basically a gray box located between your solar panels and the inverter. This action will interrupt the flow of DC power from the panels.

Step 4: Now, power off the electrical service panel. Then, find the breakers dedicated to your solar system, generally labeled as Solar PV. Next, switch them to the Off position.

Step 5: Hold for a few minutes to confirm that the power system is completely shut off.

Step 6: Turn on the electrical service panel by switching the breakers to the On position.

Step 7: Switch on the DC disconnect again, which you turned off in a previous step. Once you activate the DC disconnect, you might hear a loud cracking sound which is not a major issue.

Step 8: Next, turn on the AC disconnect, which you have turned off earlier.

Step 9: Finally, switch on the inverter to complete the reset steps.

By following these soft and hard reset steps, you can reset inverter overload conditions. Generally, the hard reset process is the first step in solar inverter troubleshooting options. If it displays a yellow or red signal, performing a hard reset can be helpful to resolve minor glitches. However, it is best to refer to the user guide or consult a licensed solar installer for specific details about your solar inverter. Note that you have to be patient throughout the process as it may take some time to fully reboot and reset your device. Moreover, remember that the presence of a physical reset button on the inverter may differ from the inverter models.

In order to reset an RV inverter, it is recommended to first try a soft reset. The process of soft reset is very basic which is like restarting your computer to resolve software problems. However, the steps may vary depending on the exact model. Here is a general guide on how you can reset the RV inverter:

Step 1: Locate the Power ON/OFF switch.

Step 2: Next, press and hold the Power ON/OFF switch for approximately fifteen seconds until you see the Charging/Inverting Status LED display begin flashing rapidly.

Step 3: When you notice the rapid LED flashing, release the Power ON/OFF switch.

Step 4: Once you release the Power button, the Status LED will turn off automatically.

After you are done with the soft reset process, if it doesn’t solve the issue, check out the manufacturer’s manual. You can also call customer support for troubleshooting steps for your specific RV inverter model.

What are the Possible Outcomes of Not Resetting an Inverter?

inverter: how to reset inverter fault

Since you are already aware of how to reset inverter fault, you must know what would happen if an inverter is not reset. Not resetting your inverter for a long time could result in various potential consequences. One major outcome may be the inverter operating at low voltage levels, which is generally harmful to its battery. It could cause overload conditions, resulting in a continuous alarm noise. It might also shut down due to excessive heat issues.

To sum up, we have discussed how to reset an inverter fault, covering both soft and hard resets. These methods effectively address common issues that may arise with the inverter. Soft reset through apps or software easily restores default settings, while a hard reset includes physical steps. However, it is essential to consult the user guide or seek advice from a licensed solar installer before proceeding with any reset, as the process can vary depending on the specific model.
