Yes, DELTA Max Extra Battery is compatible with both DELTA Max models, 1600 and 2000. Each supports up to two Extra Batteries.

Different power stations have various conditions that prompt the fan to start running of fan operation, for RIVER series, you can set that manually in the app, or set it to always be on.

For DELTA (1300), the fan will turn on when the internal temperature is greater than 45°C.

Yes, but please note:

– The transfer switch should be connected to the power station’s AC output port;

– You should disconnect the circuits from the grid before they are supported by the power station;

– The total power consumption of the circuits should not exceed the output power rating;

– The output will not be grounded if the power station is not connected to the grid.

We do not have an official solution for wind turbine charging yet. However, a DIY solution is possible at your own risk. (As long as wind power meets our input XT60 port and AC inlet requirements of the power stations)

No, this is because the car charging and solar charging cables share the same input (XT60 outlet).

Yes, we recommend connecting 2 same units in series at most. Furthermore, please also note:

1. The slave unit must be fully charged before being connected.

2. Must not charge the main unit when the slave is connected.

So far, DELTA Pro/Smart Home Panel/Solar Tracker have a bluetooth module and can connect to the app via bluetooth. Other models without bluetooth can connect to the app via IOT or Direct Connection.

You can connect the power station to the app in three ways—Direct Connection mode, IOT mode, and Bluetooth (only for DELTA Pro).

Please check the link below for our app user manual. Connection modes instructions are provided in detail on pages 4-9. APP user manual : (https://cdn.shopify.com/s/files/1/1996/9707/files/APP_user_manual_updated1103.pdf?v=1635933130)

In addition, we have a video tutorial on this topic here: https://youtu.be/9oUPsj8FlTk

Discharge the unit to 0%, then charge to 100% until there is no input.

Perform three times SoC calibration by doing three complete charges and discharges.

The XT60 car charger is a standard outlet. Use the included 1.5m car charging cable to charge.

1. Make sure the battery has sufficient capacity. If not, charge and turn it on again. If charging continues to fail, please follow the instructions on charging failures.

2. If there is no response after you short press or long press (3 seconds) the Main Power Button, contact EcoFlow Customer Service.

1. The battery is running out and needs recharging.

2. The default standby time of this product is 2 hours and can be set on the app. If the switches for the AC/DC outlets are not turned on and the product is not connected to any load, the product will automatically shut down after 2 hours. The default standby time can be set in the Ecoflow App.

1. If DELTA Max is placed on a carpet, move it to a wooden floor or solid flooring.

2. Take a video showing the error and contact [email protected]

1. To prolong the battery life, we recommend that you use and store the product in an environment of 20°C to 30°C, away from water, heat, and metal objects.

2. For long-term storage, discharge the product down to 30% and then charge it up to 60%. Continue to follow this procedure every 3 months. Units that are not charged and discharged for more than 6 months will no longer be covered under warranty.

3. For safety reasons, please do not store this product in an environment above 45°C or below -10°C over a long period.

1. If DELTA Max is charging from an AC outlet, confirm that the AC switch is turned on. The same goes for DC outlets.

2. If the AC or DC switch is turned on and it still cannot be charged, confirm whether the output power of DELTA Max meets the rated wattage of the electrical appliance.

3. When the power from a DC source or car charger is less than 1 watt, the charging power will not be displayed, but the unit is charging. Try charging from another power source to see if the charging power is displayed.

4. When the screen displays an overload alarm, the charging power is too high. Shut down and allow the unit to cool down for 30 minutes, or try using a low-power device before charging again. If there is still an overload prompt, take a photo or video of the issue and contact [email protected]

5. The AC switch will automatically turn off after 12 hours if the power of the electrical appliance is less than 10W because the power detection is equivalent to zero power output.

1. The charging temperature is too high. If you use high-power electrical appliances for a long time, stop using the unit until the temperature drops.

2. The charging temperature is too low. If the outside temperature is too low or the temperature of the battery cell is lower than 0°C, put DELTA Max somewhere warmer.

3. The charging voltage or current is too low. Charge the device according to the rated charging voltage and current.

4. Change the charging method or the cable when experiencing charging issues. Replace the cable or power source.

5. If none of the above methods work, provide a video showing the fault and contact [email protected]

1. Confirm that the 12V car charger has a standard voltage and power output.

2. Use another car charging cable to see whether the problem is with the standard car charging cable. Alternatively, use a solar panel to charge DELTA Max. If the solar panel works, the problem is with the car charger to XT60 cable. If the solar panel does not charge either, contact [email protected]

1. Press the IoT button again to reconnect.

2. Use another mobile phone to set up a hotspot connection. If the DELTA Max can connect to the phone’s hotspot connection, it means that the connection function of the DELTA Max is normal. Since the WIFI connection only supports 2.4GHz, check the home router. If it is 2.4 GHz, modify the router configuration.

3. If none of the above methods work, provide a photo of the serial number at the bottom of the device and contact [email protected]

When unable to connect to the unit, the serial number is not displayed, or “Unknown” appears after binding; the serial number has not been confirmed. Please contact [email protected]
