6 FAQs about [Photovoltaic inverter fault code 120]

What does error code 120 mean on a Growatt solar inverter?

When a Growatt solar inverter displays the Error Code 120, it means that there is a problem with the current sensor. This Error Code is also known as an HCT Fault. Growatt solar inverters can experience two types of faults: system faults and inverter faults.

What is a must solar inverter error code?

Inverter is a device that converts DC power to AC and supplies electricity to our household appliances. If the inverter signals error codes, there are some potential issues that could impact the output. The must solar inverter fault/ error codes, their specific descriptions, and suggested troubleshooting is listed below: 1. Error Code E000

What are inverter error codes?

Inverter error codes are generated and displayed by inverters to notify that something wrong can disrupt the normal working of the solar PV system. The problem can be with the inverter itself, other parts of the solar system, or elements outside the system. The different inverter brands have an array of unique error codes.

What does error code w020 mean on a solar inverter?

For additional help and investigation regarding solar inverter problems and solutions, get in touch with the manufacturer. 30. Error Code W020 Description: PV Isolation Low LCD Display: PV Isolation Low Troubleshooting: Restart the Inverter: Turn off the inverter and then switch it on. This could potentially rectify temporary internal faults.

What are ABB inverter error codes?

ABB Inverters combine two systems when displaying errors. In addition to the operating status LED that flashes, they show an error code together with an error message. While the error message is in plain text, the error code is in alphanumeric characters. We’ve previously covered a few of the ABB Inverter error codes.

What does error code 111 mean on a Growatt solar inverter?

An Error Code 111 usually happens with a Growatt TL3 inverter series. When this error shows up, it means that there is an IGBT drive fault and that you should already contact your solar inverter installer for a checkup. An Error Code 117 on a Growatt solar inverter means that there is a problem in the relay circuit.
