DELTA SERIES - FREQUENTLY ASKED QUESTIONS
What’s the max input DELTA Pro can achieve?
When charging DELTA Pro and its extra battery together, you can reach 6500W max charging speeds by combining AC, solar and Smart Generator methods. For DELTA Pro single unit, you can recharge it at standard wall outlets (1800W max), at EV station (3400W max)/Smart Home Panel/240V outlets (3000W max).
How many solar panels can you use at the same time?
It depends on the combined voltage and current of the solar panels you choose. It's fine as long as the solar panels use connectors and their combined voltage and current are within 11-150 volts and under 15 amps.
How do I update the firmware?
First of all, make sure your DELTA Pro is connected to the EcoFlow App using Internet mode. Secondly, go to the Firmware section in the Setting of the DELTA Pro you're looking to upgrade. Check for the latest firmware and follow the steps to finish the upgrade.
How do I recharge DELTA Pro at 200V-240V in a 100V-120V region?
The cable provided with your DELTA Pro won’t plug into higher-voltage outlets, and you’ll need a third party adapter/charging cable.
How does the Emergency Power Supply (EPS) work? And how fast is it?When your portable power station is plugged into the wall, any electronics plugged into it are powered from the grid and not its battery. When power from the grid stops, as in a blackout, the power station automatically switches to battery power within 30ms.
How long can the product charge my devices?
The charging time is shown on the product’s LCD Screen, which can be used to estimate the charging time of most appliances with stable power usage.
Does it support charging while using?
Yes, power station supports charging and discharging when charging in vehicles,portable solar panel, etc. However, when the battery of the machine is low or is about to run out, it is best not to output while connecting to DC charging (solar/vehicle charging); at this time, if the input of the power is less than or equal to the output power, the device will continue to consume power, which may result in power loss and eventually damage the battery.
How to clean the product?
Please gently wipe it with a dry, soft, clean cloth or paper towel.
How can I know if the product is charging?
When it’s charging, the remaining charging time will be shown on the LCD Screen. Meanwhile, the charging indicator icon begins to rotate with the remaining battery percentage and the input power shown on the right of the circle.
Can I connect more than one power station together in series? (For all power stations)
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.
Can I connect EcoFlow power stations to my house electric panel directly? (For all power stations)
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.
How to store and maintain Ecoflow power station
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.
Why can't I connect (RIVER series/DELTA mini/DELTA/DELTA Max) to the app using bluetooth?
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.
Do you have wind charging solutions?
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)

When does the fan work and when does it stop? (at what temperature)
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.
Why is the car charger not working?
1. Please confirm whether the car cigarette lighter has normal voltage and power output.
2. Try using a solar panel to charge the power station. If the solar panel can be used to charge, it means that there is a problem with the car charger to XT60 cable. Change the cable, and if the solar panel still cannot be used to charge, then contact support.eu@ecoflow.com
Battery Runs Down Too Quickly
1. Please check if there are external high-power electrical appliances. If the power of the connected electrical appliance is about the same as the battery capacity, the battery will run out in about 1 hour.
2. Perform a complete charge and discharge for an SoC calibration.
Unable to Fully Charge to 100%
Perform three times SoC calibration by doing three complete charges and discharges.
How to Calibrate SoC
Discharge the unit to 0%, then charge to 100% until there is no input.
Why is my power station input power hopping when i try to charge it? How do i fix this?
To fix this, try charging and discharging the unit 3 times. If it still occurs, please provide a video demonstrating the issue and contact support.eu@ecoflow.com
Why does the car charging port not output any power?
1. Confirm whether the DC switch is turned on, and the DC switch will light up to indicate it is on.
2. Try to replace the head of the charger to see whether the cable is faulty
3. If none of the above methods work, provide a video explaining the fault and contact support.eu@ecoflow.com

DELTA Pro Won't Charge Appliances
1. If charging from an AC outlet, check 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 charge, confirm whether the output power of DELTA Pro meets the rated charging power of the electrical appliance.
3. When the power from a DC source and car charger is less than 1 watt, the charging power won't display, but the actual device is charging, try charging another appliance with a larger wattage to see if the charging power displays.
4. When the screen displays an overload alarm, the charging power is too high. Shut down DELTA Pro and leave it 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 and contact support.eu@ecoflow.com
5. The AC switch will automatically turn off after 12 hours if the power of the electrical appliance is less than 10W.
