When the ambient temperature is too low (below minus 20 degrees Celsius), the blue low temperature warning light will flash. Please move the device to a location with a suitable temperature (-10 degrees Celsius to

60 degrees Celsius) for the device to function normally. When the ambient temperature is below 0 degrees

Celsius while the device is being charged, the blue low temperature warning light will flash as well. Please move the device to a location with a suitable temperature (0 degrees Celsius to 45 degrees Celsius) for the device to charge normally.

9. Battery Level Indicator

The battery life is indicated by five lights. When the device is being charge, the lights will flash in sequence.

When the battery is malfunctioning, all five lights will flash together at the same time.

10. Battery Warning Indicator

When the battery malfunctions, the battery warning indicator will light up. Try resolving the issue by restarting the device. Alternatively, please contact customer service.

11. High Temperature Alarm Indicator

When the ambient temperature is too high (above 60 degrees Celsius), the red high temperature warning light will flash. Please move the device to a location with a suitable temperature (-10 degrees Celsius to 60 degrees Celsius) for the device to function normally. When the ambient temperature is above 45 degrees

Celsius while the device is being charged, the red high temperature warning light will flash as well. Please move the device to a location with a suitable temperature (0 degrees Celsius to 45 degrees Celsius) for the device to charge normally.

12. 24V +/- ON/OFF Button

Press and hold the button to turn the 24V+/- on and off. To use the 24V terminal, connect the wire and tighten it. Check if the connection is correct before turning on the 24V +/- ON/OFF button.

R600 PRO TO EF-1500 CONNECTION

Get the R600 PRO, EF-1500 and expansion power cable ready. Then turn off the power of R600 PRO and

EF-1500. Follow the steps below. If the devices are not turned off, they cannot be successfully connected.

1. Open the soft cover below the AC port of R600 PRO to expose the expansion power port. Connect the expansion power cable to the port. Tighten the screws on both sides of the port to secure the connection.

2. Open the dust cover of EF-1500 to expose the expansion power port. Connect the other end of the expansion power cable to the port. Tighten the screws on both sides of the port to secure the connection.

3. Turn on the power button of R600 PRO, followed by that of EF-1500. If the display of R600 PRO shows the expansion battery pack icon, the connection is successful. When connecting the devices for the first time, it is recommended to fully charge them first. Fully charge R600 PRO and EF-1500 and ensure that the voltage of both devices are consistent to maximize the performance of EF-1500.

SOLAR PANEL CONNECTION

How to recharge the EF-1500 using solar panels?

To connect a single solar panel, please refer to the following instructions. The connection of a single solar panel and two solar panels in parallel are shown. The EF-1500 can support a 10-25V DC input. When the input exceeds 25V, the EF-1500's overvoltage protection will be triggered. Excessive voltage may damage the product. User should follow these instructions. EcoFlow will not be responsible for providing free repair services for any damage to the product caused by connecting too many solar panels to the product or incorrect connection, even during the warranty period.

1. Serial/Chainable connection (recommended)

Users can connect a solar panel (series connection is not supported) as shown in Example 1. Connect the panels to the MC4 port and connect them to our MC4 to XT60 conversion cable. Connect the XT60 cable to the EF-1500’s XT60 input to charge the device. Users can connect up to 2 sets of solar panels in parallel to the MC4 port as shown in Example 2. If you want to connect 2 pieces of solar panels, you can connect the 2 sets of solar panels in parallel. Connect them our MC4 to XT60 conversion cable. Connect the XT60 cable to the EF-1500’s XT60 input to charge the device. The parallel connection cable is an optional accessory that is purchased separately.

FAQs

How do I care for EF-1500?

The EF-1500 is versatile, so it is likely that simple cleaning will be required from time to time. Use dry, non-abrasive cloth to wipe. If you want to wipe more cleanly, we recommend that you use a special detergent for mobile phone and computer screen. DO NOT expose the product to large amounts of water!

How do I store EF-1500?

Please store EF-1500 in a dry place and avoid direct contact with water. In order to extend battery life, if long-term storage is required, please charge it to 30% -50%, then turn off the main switch and store at room temperature.

How do I use EF-1500 safely?

Please use EF-1500 under temperature conditions within its operating temperature range. Using EF-1500 outside the optimal operating temperature range may cause EF-1500 to exceed its safe and effective working limits. DO NOT immerse EF-1500 in water. EF-1500 is not waterproof. Doing so will void the warranty.
