PACKING LIST

HOW TO USE THE EP3000-48V

• Light press to show battery capacity
• Long press to turn on/off DC (USB/XT60 12V
• Note: The operating temperature range of EP3000-48V is -20~45℃.
• If the operating temperature is not within this range, it will fail to work.

HOW TO USE THE EP3000-48V IN CASCADE WITH THE HOST

1. Before use, make sure the EP3000-48V power pack and the host have similar battery levels, with a difference of no more than 10%.
   • If there is a significant difference in battery levels, it will take a longer time for the host and power pack to display green, indicating a complete balance.
2. When cascading multiple power packs, check the serial number knob on each power pack to ensure the uniqueness of the serial numbers. These serial numbers will correspond to the identification numbers of the power packs in the app.
   • Duplicate serial numbers can cause inaccuracies in battery levels, among other issues.
3. Use the MJ32-48V cascade cable to connect the host and the EP3000-48V power pack through the cascade port.
4. Once the connection is completed, the status LED of the EP3000-48V power pack should display either yellow or green.
   • Yellow indicates a significant difference in battery levels, indicating that the balancing process is in progress. Green indicates that the power pack and the host are fully balanced. (If you need to use high-power devices, please wait for complete balance.)

HOW TO INSERT AND REMOVE THE CASCADE CABLE

Adjusting the angle of the cascade cable:

• Before insertion, determine the desired angle and grip the plug. Within the range of the rotating arrow, you can rotate it 90° clockwise or 90° counterclockwise.
• (Do not exceed this angle and do not rotate after insertion.)

Inserting the cascade cable:

• With the “PUSH” button facing upwards, align it with the corresponding socket. Push it forward until you hear a “click” sound, indicating that it is inserted in place.

Removing the cascade cable:

• Press down and push the “PUSH” button downward, grip the plug, and pull it outward.

CASCADE PROCESS NOTES

1. When cascading multiple EP3000-48V units, it is important to maintain the uniqueness of the serial numbers.
2. Without connecting to the host, EP3000-48V units cannot be connected or activated.
3. After completing the cascade connection, when using EP3000-48V units, the charging and discharging power may not be displayed on the host screen, but the host will calculate their battery levels.
4. After completing the cascade connection, when the host is powered on, the power packs will perform a self-check, and the status lights may have a delayed response (within one minute). This is normal.
5. After completing the cascade connection, when the host is powered off, the power packs will wait to be fully balanced with the host before shutting down.

STACKING AND SECURING MULTIPLE POWER PACKS

1. First, remove the protective corners from the power packs you want to stack and align them with the positioning structure, placing them on top of each other.
2. Use screws and metal connecting pieces to secure the stacked power packs from top to bottom.
3. Install the protective corners in the following order: align the side with the positioning structure first, then snap the front side into place. Install them one by one until they are properly positioned.
4. After installation, as shown in the diagram, to ensure safety, stack a maximum of four EP3000-48V power packs.

(The protective corners in the middle of the power packs are for aesthetic purposes only and do not provide structural strength.)

HOW TO CHARGE THE EP3000-48V BATTERY PACK BY VEHICLE

RECHARGE TIME

SOLAR CHARGE TIME

• Note: The above data comes from PECRON’s laboratory. Actual charging time depends on the weather conditions.

USING SOLAR PANELS TO CHARGE THE EP3000-48V

• GX16MF-5 Charging Port: PV (operating voltage) range 12V~95V, 400W maximum; VOC (open circuit voltage) of solar panel/array must be less than 95V, otherwise, it will damage the unit! Do not wire more than two 36V solar panels in series, or more than four 18V solar panels in series. (18V/36V stands for Vmp, the operating voltage, of the solar panel)

USING SOLAR PANELS TO CHARGE THE EP3000-48V

• Charging the EP3000-48V with a single solar panel
• It is recommended to choose PECRON solar panels for optimal user experience! The VOC of a single solar panel should be less than 95V, and the VMP should be greater than 12V.
• Charging EP3000-48V with two solar panels in series
• It is recommended to choose PECRON solar panels for optimal user experience! The VOC of a single solar panel should be less than 95V, and the VMP should be greater than 6V.

FAQS

Q1: What kind of battery is used in EP3000-48V?

• A: EP3000-48V utilizes high quality UL-certified automotive LiFePO4 battery.

Q2 What machines can the EP3000-48V power pack be cascaded to?

• A: Currently EP3000-48V power pack can be cascaded to machines with MJ32 cascade port.
• Q3: After the EP3000-48V power packs are cascaded, can the EP3000-48V power packs be used to charge or discharge?
• A: Yes, but the charging and discharging power cannot be displayed on the host separately, the current and voltage of each battery pack can be viewed through the APP.

Q4: How to calculate the EP3000-48V running time?

• A: Running Time=Total Capacity(3072Wh) * 0.85 (Depth of Discharge)/Loading Power(Watts)

Q5: Does EP3000-48V have a built-in MPPT controller?

• A : Yes, EP3000-48V has a built-in MPPT charge controller, which supports 12V-95V(max 400W).

Q6: How many EP3000-48V power packs can be cascaded to the host at most?

• A: Each MJ32 port can be cascaded up to two. If the quantity is more than two, the resistance between the host and the power pack will increase, and the voltage difference will also increase, causing the cascaded battery to fail to function properly.

Q7: How to store the EP3000-48V?

• A : When storing, please first turn off the product and then store it in a dry, ventilated place with a room temperature
  environment. Do not place this product near water sources. When storing for a long time, it’s recommended to discharge the battery to 30% and then recharge it to 60% every three months to extend the life of this product.

Q8: Other issues to be noted.

• A: Pay attention to the point that the product is without a waterproof function and prevent water from getting into it.
• Pay attention to ventilation and heat dissipation when using, and keep good ventilation at the air inlet and outlet of the product.
• Do not use the product on special occasions (under the mine, gas station, etc.)
