Quick Answer
To reset a SmartSolar charge controller, press and hold the M button while turning on the system, then release the M button after 10 seconds, and finally turn off the system and restart it to complete the reset process.
Resetting the SmartSolar Charge Controller
Press and hold the M button on the Victron Energy SmartSolar MPPT charge controller while turning on the system, ensuring that the charge controller’s LEDs are illuminated. This step should be done within 10 seconds of system power-up. Release the M button after the 10-second countdown, and then turn off the system.
Confirming the Reset
Turn the system back on to verify the reset was successful. You can confirm this by checking the charge controller’s display for a message indicating a system reset or by checking the Cerbo GX monitoring system, if connected. If the reset was successful, the charge controller’s settings will be restored to their default values.
Important Notes and Precautions
When resetting the SmartSolar charge controller, be aware that any custom settings will be lost. This is a deliberate action to ensure that the system returns to its default settings in the event of an issue or to facilitate troubleshooting. If you rely on specific settings for your off-grid system, consider documenting them before resetting the charge controller. Additionally, ensure that you have a backup power source available to prevent any disruptions to critical systems during the reset process.
