Troubleshooting: Why won't my Boulder panels charge the Yeti?

They may not be connected properly, there may be an issue with the Boulder’s charging settings, or the Yeti’s lithium battery may be damaged.

Checking Connections and Settings

First, verify that the Boulder panels are properly connected to the Yeti. Ensure all connections are secure and not loose. Check the Boulder’s charging settings to make sure they are set to the correct mode (e.g., 12V or 24V) and that the Yeti’s input voltage range is not exceeded. It’s also essential to check the Yeti’s state of charge (SOC) meter to ensure it’s functioning correctly.

Troubleshooting Charging Settings

The Boulder’s charging settings can be adjusted using the Boulder’s app or the physical controls. Check if the charging speed is set too low, which may prevent the Yeti from charging efficiently. Try increasing the charging speed to see if it resolves the issue. Additionally, make sure the Boulder’s charging profile is set to the correct type (e.g., ‘Lithium’ mode for lithium batteries).

Investigating Battery Damage

If the Yeti’s SOC meter is not functioning correctly, or if the battery is old, it may be damaged. Check the Yeti’s battery health by monitoring its voltage and SOC over time. A damaged battery may not hold a charge or may not charge properly. If you suspect battery damage, try replacing the battery or visiting a Goal Zero authorized service center for further assistance.
