Quick Answer
To troubleshoot a Yeti that won't charge, check the input voltage, ensure the Boulder panel is properly connected, and inspect the charging port for blockages. Verify the panel's solar output and the Yeti's charging circuit. Consult the user manual or contact Goal Zero support if issues persist.
Inspect the Charging Circuit
When the Yeti won’t charge, inspect the charging circuit, which typically involves the Boulder panel’s output, the charging port, and the Yeti’s charging board. Ensure the charging port is clear of debris and properly seated. Check the charging board for any signs of damage or corrosion. Verify that the charging board’s fuses haven’t blown, and replace them if necessary. Consult the user manual for guidance on locating and replacing fuses.
Verify the Boulder Panel’s Output
Verify the Boulder panel’s output voltage and current by checking the panel’s display or using a multimeter. A minimum of 18V DC output is required for the Yeti to charge. If the panel’s output is below 18V, check the panel’s connections to the Yeti and ensure they are secure. Also, verify that the panel’s voltage regulation is functioning properly.
Power Cycle and Reset the System
If none of the above steps resolve the issue, power cycle the system by disconnecting the Boulder panel from the Yeti and the Yeti from the load. Wait for 30 seconds before reconnecting the components. This will reset the charging circuit and may resolve any software-related issues. If problems persist, consult the user manual or contact Goal Zero support for further assistance.
