Customer Question
Hello, I have a...

Hello, I have a JFY solar inverter that has fault on it. "DCinj Failure" can you tell what this means? Is it a fault with the inverter or with the solar panels?

Contractor's Assistant: Have you talked to a solar panel professional about this?

Sorry my name is*****: Do you plan on doing the work yourself?

I am an electrical engineer but will probably get an electrician to do any work required

Contractor's Assistant: Anything else we should know to help you best?

The solar system has been installed for about 5 years and up till now the only problem has been with two solar panels that were disconnected last year.

Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) “DCinj failure”, means output current DC offset is too high. The problem is within the inverter.

2) Have you tried to power down the inverter and re-start it to see if the trouble code goes away?
