Sometimes the Renogy wanderer solar charge controller will give an error code. In order to fix this you need to unplug the solar panel then unplug the batter.
I am running into a fault error on invertor while trying to switch. Please look at pics of connections. The controller show E01 error. Checked the connection points. All show about 10 V. (Less than 12v). Is this to do with sun not being bright enough? It did work for about 6 hours or so when I assembled first. Let me know if more pics are needs.
I recently installed a starter kit system, paired with an inverter an LED flood light. I'm using a pair of these to illuminate a flag pole 24x7. The light has an auto dusk-to-dawn sensor. After a few days, I'm getting an E1 error: Over-discharging. I think I have identified the problem but want to confirm if I can.
E01 Error; Below are the corresponding troubleshooting steps for different problems. Battery Low-Voltage Alarm. When a Rover Li Charger Controller shows Battery low-voltage alarm, follow the steps below: Check if the battery voltage settings on the controller are correct. Observe if the fault indicator light on the controller is constantly lit.

6 FAQs about [Solar power panel e1 fault code]
What are solar charge controller error codes?
Solar Charge Controller Error Codes: Your Comprehensive Guide to Troubleshooting and Fixes - Solar Panel Installation, Mounting, Settings, and Repair. Solar charge controller error codes are a set of messages that indicate specific issues or faults in the controller’s operation. The meaning of these codes varies between models and manufacturers.
Why is my solar controller not recharging?
All indications are that you drained the battery dry and you are not recharging it. Did you first connect the controller to the battery before connecting the solar panels? The controller needs to boot up first ONLY on battery power before the circuitry can properly accept the solar input. Lastly, you appear to have your battery wired improperly.
What does E01 & E02 mean on an MPPT controller?
For MPPT controllers, E01 usually represents an overcurrent warning, while E02 warns you of high PV voltages. Responding to these alerts can save your system from severe damage! Brands like Victron Energy and Zamp have specific error codes that range from Err 1 to Err 24 and Fault Code: B01 – 601.
How do I know if a load is E01?
Test the current on the load port and observe the actual current value. If a load is connected, also check for any short circuits in the load wiring. Additionally, confirm if the load specifications exceed the allowed limits. For E01 error, see the troubleshooting video below. Still have problems?
What does E01 E02 E04 E05 mean?
These codes usually indicate different issues related to the battery such as e01 (Battery Over Voltage), e02 (Under Voltage), e03 (Over discharge), e04 (Over Load), and e05 (Load Short Circuit). Promptly responding to these error codes can enhance your system’s longevity.
Why should you use a solar charge controller?
More significantly, during periods of intense sunlight, it prevents your batteries from overcharging, subsequently increasing their lifespan. There are two main types of solar charge controllers – Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT).
