When you encounter error codes on your Thunderbolt Solar Charge Controller, it’s essential to troubleshoot the issues promptly. Effective troubleshooting can help identify and resolve problems, ensuring your solar power system operates smoothly. Here’s how to do that – Error Code E01: Battery under voltage

What does error code E01 mean?

Error Code E01: Battery Under Voltage This error indicates that the battery voltage is below the acceptable threshold. When the battery voltage is too low, it can damage the battery and affect system performance. The most common causes include aging batteries, a malfunctioning solar panel, or a problem with the charging circuit.

Why is my solar panel overvoltage?

This can damage the charge controller and the battery. Overvoltage issues are often related to a faulty charge controller or mismatched solar panels. To rectify this problem, you should inspect the charge controller, check the solar panel specifications, and replace any components if necessary. Error Code E05: Solar Panel Reverse Polarity

Will a solar panel produce 100% of its rated power?

However, a solar panel will generally not produce at 100% of its rated power in real-world conditions due to one or more of the issues and loss factors listed below. On average, a solar panel will generate around 80% of its rated power depending on the orientation, season and air temperature.

How do I know if my solar system is working?

Check the solar system performance data on the app and website, if available. Check the solar panels for dirt, leaves, mould, or shade issues. Check the solar inverter for any warnings or faults. Check that the isolators are all on and that the circuit breakers have not tripped off.

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.
