To toggle through the info menus, the user can HOLD down the INFO button, and SHORT PRESS the UNITS button. Each SHORT PRESS of the INFO button will toggle to the next page in the menu. The abbreviated name of the current menu page will be displayed when toggled in the bottom left section of the LCD display.

tPS – (Page 1)

HOLD INFO, PRESS UNITS 1 time to show internal temperature readings in degrees Celsius.

• t1 – temperature of the battery input/output FET
• t2 – temperature of the internal battery cells
• t3 – temperature of the AC inverter

Example

The above example shows:

• 22°C for the internal battery cells
• 22°C for the battery input/output FET
• 25°C for the AC Inverter

SoH – (Page 2)

HOLD INFO, PRESS UNITS 2 times to show the battery State of Health rating.

The battery's State of Health is the usable battery range where 100% is a battery that is able to use the full capacity of all cells as they were designed in manufacturing. Batteries will degrade as the battery is cycled over its life. Using the Yeti's Charging Profiles feature can help slow the degrading and improve the lifespan of the battery.

Example

The above example shows a battery with a 95% State of Health.

HOLD INFO, PRESS UNITS 3 times to show the Firmware Versions (Build Number) of various internal components. Generally, the versions should be the same across the components per update, but this is subject to change.

• F1 – Firmware Version of the Charge Controller (CC)
• F2 – Firmware Version of the Wireless (Wifi) Module (or the Connected Accessory)
  • See the Display Firmware Versions page for more.
• F3 – Firmware Version of the Main Control Board (MCB)
• MOD – Model Number

Example

The above example shows:

• Charge Controller: v1.5.4
• Main Control Board: v1.5.5
• Wifi: v1.5.6
• Model Number: 5

To show the firmware version of the connected Accessory (i.e. Yeti External MPPT Module, or Yeti Link Module), you must first be showing Watt-Hours in the Units segment. More info on the Display Firmware Versions page.

The Yeti keeps track of the number of battery cycles it has been through in its lifetime. One battery cycle is essentially a full discharge to full charge. HOLD the LIGHT and the INFO button together for about 4 seconds. The number of Battery Cycles will be shown in the INPUT number segment.

Find out more about the Charging Profiles Feature

To toggle between Charging Profiles, HOLD the UNITS button and PRESS the 12V button.

The LCD will display an abbreviated name for the selected Charging Profile and will show the charge points in the number segments on the LCD as illustrated here:

If the user has not yet defined a Custom Charging Profile via the app, they will only be able to toggle between Performance, Battery Saver, and Balanced. If the user has setup a Custom Charging Profile via the app, they will be able to toggle between Performance, Battery Saver, Balanced, and Custom.

When the Yeti ships from our warehouse, the Wifi will wake up every 24 hours to check for automated Factory Firmware Updates. The Wifi wakes, performs a Wifi scan searching for a dedicated network SSID. If the network is not found, it will go back to sleep within about 30 seconds.

As soon as the user takes the Yeti out of the box and pairs with the Yeti with Yeti App in Cloud Connect mode, the Auto Update Wake feature will be disabled and cannot be re-enabled until the unit is factory reset. So now, if the Wifi is turned off, the Wifi will no longer wake every 24 hours.

Some customers may wish to never pair their Yeti with the App and also wish that the Wifi will stay off indefinitely. For this use case, the user may do the following to disable Wifi Auto Update Wake.

HOLD the WIRELESS button and PRESS the RESET button:

• "Off" will be displayed on the LCD when disabled

• "On" will be displayed on the LCD when enabled

When the battery is drained via the output ports, the energy out is measured and counted in Watt Hours. This number will persist indefinitely unless the user resets it or performs a Factory Reset. To reset the Watt-Hours counter, Press and Hold the UNITS button for about 4 seconds until a beep is heard. The Watt-Hours counter should now read 0.

NOTE: Resetting the Watt-Hours counter will not impact the Energy Usage History feature.

When the user presses the UNITS button. The OUTPUT segment on the LCD changes to display different parameters

The Yeti can be put into Sleep mode to preserve the battery for long-term storage. The Yeti will enter sleep mode when:

• There is no charge input connected
• All output ports are disabled
• Wifi is turned off
• LCD backlight is off

To Charge the Yeti via the USB-PD Input/Output Port:

1. Set the USB Port to the On state by pressing the USB button
2. Connect the USB-PD power source
   1. If the Yeti doesn't start charging
      1. Disconnect the USB-PD power source
      2. Turn off the USB port by pressing the USB button
      3. Turn the port back on by pressing the USB button
      4. Reconnect the USB-PD power source
   2. If the Yeti is still not charging
      1. It's possible the USB-PD power source needs to be reset
      2. Disconnect the USB-PD power source from the wall, and try the above steps again.
   3. It's also possible the PD charger is somehow not compatible with the Yeti
3. It's also possible to charge via the USB-PD Input/Output port when the Yeti is at the Minimum Discharge Point (or 0% in most cases).
   1. Pressing the USB button when the Yeti is discharged all the way, will enable USB-PD input charging only and won't allow output.
   • The USB LED will blink if it is in PD INPUT mode only.

Toggling the Wifi enable, means to go from OFF to ON or from ON to OFF. If the Wifi is OFF, a short PRESS of the WIRELESS button will turn it on. The Wireless module will go back to the mode it was in before it turned off.

To Toggle the Wifi Enable, PRESS the WIRELESS button.

If the Yeti has been paired to a nearby network before and is currently in PAIRING mode, the user can get the Yeti back on to the nearby known network by switching from PAIRING mode to CONNECTING mode. This removes the need to reconnect using the app. The Wifi will wake and search for known networks.

To Toggle the Wifi Mode, HOLD the WIRELESS button for about 4 seconds.

If anything seems to be behaving in an unexpected way, sometimes a Soft Reset is all that is needed to recover back to normal behavior.

To Reset the Yeti, HOLD the RESET button for about 4 seconds.

While the Yeti is in use, it stores various bits of data long-term in internal memory. This data can be cleared by performing a Factory Reset. The data that is erased from a Factory Reset is:

• Energy Usage History
• Local Network Connection information
• Firmware Update files
• Custom Charging Profile configuration

To perform a Factory Reset, the user can HOLD the UNITS and INFO buttons together for about 5 seconds.

The Yeti will beep and show the "Updating" Screen until the Factory Reset is complete:

Previously paired devices will no longer be able to monitor and control the Yeti and will need to be re-paired.

There have been reports that some Yetis can reach a state where they are unable to receive a charge. To help resolve this issue, or other issues that a simple Reset can't resolve, Yeti's running firmware v176 or newer can perform a Battery Shutdown. A Battery Shutdown completely cuts power to the system for up to 1 minute. This reset should reset all components in the system to get it back into a functional state.

• Battery Shutdown
  • 1500X/3000X/6000X Hold INFO + RESET (under the lid) for about 10s
  • 1000X/1000-Core Hold INFO for about 10s
    • The system will shutdown and be unresponsive for up to 1 minute
    • Once the system restarts, it should function/charge as normal

1. HOLD the Wireless Button for about 4 seconds until you hear a beep
2. 
3. The Yeti will switch to PAIRING MODE
4. Wait about 10 seconds
5. Again, HOLD the Wireless Button for about 4 seconds until you hear a beep
6. 
7. The Yeti will switch back to WIFI CONNECTING MODE
8. Once the Yeti is back online and in CLOUD CONNECTED MODE, the update should resume.

• NOTE: there won't be any progress shown in the app. You may observe the Yeti LCD screen to monitor progress.
