6 Frequently Asked Questions about “Solar power controller display code”

What is error code E02 on solar charge controller?

like e01 on solar controller, e02 is another common fault code, The error message is also point to the load, reconnect or replace the load to fix it. The solar charge controller will display an error code if there is a problem. The solar charge controller error codes are not always the same.

What does a solar panel error code mean?

The solar panel error codes will tell you to disconnect and reconnect the panels to restart the charging process. If the error message persists, you may need to manually reconnect the batteries. If this does not work, the controller may be faulty.

Why is my solar charge controller error code flashing?

An error code flash on your Solar Charge Controller indicates a problem has occurred. Here's a reference list to help you determine what the problem is and what steps to take. Some errors can be fixed by yourself with some simple troubleshooting. This will help you get your solar charge controller back up and running.

What does error code E05 mean on a solar panel?

E05 – Solar Panel Over Current, Controller stop working solar charge controller Error code E01 appears when the battery bank is at low voltage and the charge controller cannot charge it. To correct this, first charge the battery bank using AC chargers or replace the battery with a new one.

What is a fault code for a solar panel?

Fault Code Basics E01 – Battery Low Voltage or Load off E02 – DC load overload or Load off E03 – Load short circuit or Load off E04 – Battery Over voltage or Load off E05 – Solar Panel Over Current, Controller stop working

How do I know if my solar controller is not working?

Determine if this clears the error state. If there is a moon symbol appearing on the controller then the controller is not seeing voltage coming from the solar panels. The first step here is to remove the wires on the back of the controller coming from the solar panel. Use a multimeter to measure across the two leads.
