How do you reset a solar charge controller?

To perform a hard reset:

1. Take the solar controller off the wall.
2. Disconnect the 4 wires at the back (battery positive, battery negative, panel positive and panel negative)
3. Wait 15 to 20 minutes.
4. Reconnect the battery positive and negative wires first. Then reconnect the solar positive and negative wires.

What does E11 mean on a solar charge controller?

Low-voltage protection
E11: Low-voltage protection; battery voltage is below 10.5-10.8V. Controller will shut off and enter low-voltage protection state.

Why is my solar charge controller not working?

If the solar battery is hooked to the solar system but doesn’t charge properly, the failure is likely to be caused by a battery problem, wrong system wiring, or a problem with the solar charge controller settings.

How do I know if my charge controller is bad?

The easiest way to test if the solar controller is working is to use a multimeter to test the output voltage. and look to the controller’s LCD display and Led indicator, if the output voltage is absent or very low, It means that the controller is not working properly.

What does E01 mean on solar charge controller?

E01 says the battery is over discharged. Probably not enough charge in the battery to activate the controller, minimum 9 volts.

Why is my solar controller not working?

If the solar battery is hooked to the solar system but doesn’t charge properly, the failure is likely to be caused by a battery problem, wrong system wiring, or a problem with the solar charge controller settings. If the actual voltage of the battery is less than 20\% of the nominal voltage.

How can I check that my solar controller is working?

How do I know if my solar panel is charging my battery?

Write down the voltage in volts. Reconnect the wires and let the solar panel charge the battery during the day. At the end of the day, measure the voltage again. You should see that the voltage of the battery has increased, indicating that it is being charged.
