Learn about Xantrex Freedom SW Error Code 01, its meaning, causes, and solutions for DC undervoltage issues.
Error Code 01 indicates a DC undervoltage condition in the Xantrex Freedom SW inverter. This can lead to system shutdown or reduced performance.
To troubleshoot DC undervoltage, check the battery voltage levels and connections. Ensure that the batteries are charged and functioning properly.
The '01' code indicates a DC undervoltage condition. The inverter continuously monitors the input voltage from the solar array. If the measured voltage falls below a predefined threshold, typically due to insufficient input from the solar modules, the inverter triggers this fault to protect itself from potential damage. This can occur if the insulation resistance (RISO) is compromised or if there are ground fault detection issues. The inverter's protective logic is designed to shut down to prevent further complications, ensuring safety and longevity of the system.
When the Xantrex Freedom SW inverter displays '01', the LED indicator may flash or change color, typically signaling a fault condition. Users may also notice alerts in the monitoring app indicating a drop in power production or system performance. The inverter may not output power to the load or grid, resulting in a complete halt in operation.
Always ensure that any electrical work is performed by a licensed electrician or certified solar installer to prevent injury or damage to the system.
To prevent '01' from occurring in the future, ensure regular maintenance of the solar array, including cleaning and inspection of modules and wiring. Implement a monitoring system to detect performance drops early, and periodically check the health of the battery bank if applicable. Additionally, ensure that the inverter is configured correctly during system and after any system changes.
