Phocos Solar Inverter – Error Code 11

Is your Phocos solar inverter showing up with Error Code 11 on the screen? In this article, we’ll look at why it is happening, some potential next steps for fixing error code 11 and whether you should keep using your Phocos solar inverter.

What is a Phocos Error Code 11?

The Phocos Solar Inverter has an Error Code 11, which means that: Error Code 11 on the Phocos Solar Inverter indicates a problem with the solar charge controller. Specifically, it means that the voltage from the solar panels is too high for the inverter to handle. This can happen when there is excessive sunlight or when the solar panels are producing more power than the inverter can handle.

When this error occurs, it is important to take immediate action to prevent damage to the inverter. One solution is to check the solar panels and make sure they are not receiving too much sunlight. If they are, adjusting the angle or shading them can help reduce the voltage. Another option is to install a voltage regulator or a device that can limit the amount of power going into the inverter. It is recommended to consult a professional or the manufacturer for further assistance in resolving this error.

Recommended solution/fix steps

To fix Phocos Solar Inverter Error Code 11, follow these steps:

1. Turn off the solar charge controller and disconnect it from the power source.
2. Check the solar panels and wiring for any signs of damage or loose connections.
3. If everything looks fine, measure the voltage output of the solar panels using a multimeter.
4. If the voltage is too high, you may need to add a voltage regulator or adjust the settings on the charge controller.
5. Consult the user manual or contact the manufacturer for specific instructions on adjusting the settings.
6. Once the necessary adjustments are made, reconnect the charge controller to the power source and turn it back on.
7. Monitor the system for any further error codes or issues. If the problem persists, seek professional assistance
