How it Works
The Goal Zero Tank PRO 4000 must be used with a Yeti PRO 4000. Together, they increase your energy storage capacity. The Tank PRO 4000 is a chainable 4000Wh Lithium Iron Phosphate Battery that adds an additional 4000-Watt hours to your home, RV, or off-grid storage system. Once the Tank is connected to the Yeti and the stabilization period is complete, the power will be sourced equally across the devices so they operate like a single unit.

Set Up Instructions

• The Tank PRO 4000 is designed to stack with the Yeti PRO 4000. The Yeti PRO 4000 should always be at the top of the stack.
• The Tank PRO 4000 is designed to securely attach to the bottom of the Yeti PRO 4000 with a fixed bracket on one side and a latch on the other.

First Tank PRO 4000

1. Place the Tank PRO 4000 on a flat level surface or Mounting Plate.
2. The side of the Yeti PRO 4000 closest to the fixed bracket on the Tank PRO 4000 will be installed first.
3. Lift the Yeti PRO 4000 with the side facing the fixed bracket tilted slightly downward.
4. Align the bracket on the Tank PRO 4000 with the slot on the bottom of the Yeti PRO 4000 and slide into place.
5. Ensure that the feet on the Yeti PRO 4000 are aligned with the feet pockets in the lid of the Tank PRO 4000.
6. Once aligned, lift and align the latch on the opposite side of the Tank PRO 4000 with the slot in the bottom of the Yeti PRO 4000 and lock into place.
7. Plug the Tank PRO cable into the QS10 port on the Yeti PRO 4000. If using extension cables, plug the Tank PRO cable into the female end of the extension cable, then plug the extension cable into the Yeti PRO or Tank PRO 4000.

Subsequent Tank PRO 4000 Setup

1. Turn off the power on all devices.
2. Unplug the Yeti from existing Tanks.
3. Unlatch the brackets that connect your Yeti PRO 4000 to the Tank.
4. Carefully lift the Yeti off of the Tank and set it aside. Two person lift required.
5. Lift your new Tank and align it with the feet pockets on the Tank you are stacking it on. (Be sure it is facing the same direction as the Tank below it)
6. Follow steps 2-7 in the section above.

Pairing the Tank PRO 4000 with the Yeti PRO 4000

1. Ensure Tank PRO 4000 power switch is OFF.

2. Plug the Tank into the Yeti (See page previous section for instructions on how to plug in QS10).

3. Switch the Tank power switch to ON.

4. Observe the Tank icon on the Yeti display.

   • The Tank icon on the Yeti will appear when the Yeti detects a Tank.

5. Observe the Status light blinking on the Tank PRO. This indicates the Tank is equalizing with the Yeti.

   • If blinking, the Status light indicates the batteries are equalizing.
   • When the Status light stops blinking and remains on, this indicates that the Tank and Yeti power stack is ready for use and will function as one unit.C
     NOTE : It may take up to 12 hours for Tanks to equalize with the Yeti depending on how many units you have connected.

6. If adding additional Tank PRO 4000 units to your power stack, ensure the power button is turned off. Then plug the additional Tank into the previously connected Tank. Once connected, you can turn the power on.

Using Your Product

Power On/Off
Press the power button on the Yeti PRO 4000. Move the power switch on the Tank PRO 4000 into the ON position. The LED Battery lights on the front face of the device will be illuminated when powered.

Charging the Tank PRO 4000
The Tank PRO 4000 will charge when it is hooked up to the Yeti PRO 4000, either through electrical grid power or solar, depending on what you’re using to charge the Yeti PRO 4000. When you connect one or more Tank PRO 4000 expansion batteries to a Yeti PRO, the Tanks and Yeti will first equalize. While the units are equalizing, the Yeti display will show charge state of the unit with the highest charge. Once equalization has finished, the units will all function as one battery and the charge state shown on the display will reflect the charge of the entire power stack.

Storage and Maintenance
Store your Tank PRO 4000 in a climate-controlled, dry location. Be sure to turn the power switch off before storing. If you can’t keep your expansion battery plugged into a power source during storage, charge the unit once every 12-18 months. Failure to maintain your Tank PRO 4000 by following these steps can result in battery damage which will void the product warranty.
