EcoFlow Delta Pro DETAILED Review and Testing solar generator
FAQ
How thick is the 2-meter-long (xx ft) Infinity Cable for DELTA Pro?
3+8 ports, power cable 10AWG, signal cable 22AWG.
How can I achieve a capacity of 25kWh?
To achieve 25kWh, you need to connect two DELTA Pro units using a Smart Home Panel and connect two Extra Battery packs to each DELTA Pro. This setup will provide 21.5kWh. If you also use our Smart Generator to charge the DELTA Pros, then 2 × DELTA Pro + 2 × Extra Batteries + 2 × Smart Generators, allows you to achieve 25kWh in a single charge.
What is the noise level of the DELTA Pro?
The DELTA Pro has a fan to keep its battery cool. At a 1-meter (xx ft) distance, the noise level ranges from 48 to 60 dB (between normal conversation and an office environment). The noise level varies depending on the wattage flowing in or out of the battery and temperature.

Can the Extra Battery directly charge DELTA Pro?
Yes.
When using the Double Voltage Hub, do I have to turn on the DELTA Pro first? Can the Double Voltage Hub directly power on the DELTA Pro?
Yes, the DELTA Pro needs to be turned on first. The Double Voltage Hub controls the AC output switch but cannot directly power the DELTA Pro on or off.
What is the peak power of the DELTA Pro Double Voltage Hub? Is there a duration limit?
The peak power can reach 9000W, but peak power duration is usually very short, lasting only tens of milliseconds.
What is the standby power consumption of the DELTA Pro?
When the AC output button is turned on, standby power consumption is approximately 30W.
Does it support dual charging (AC charging and DC charging)?
Yes, AC and DC charging can occur simultaneously, with a maximum input of 2200W.
Why is the DELTA Pro unable to charge/power my devices?
1.If charging from AC output ports, ensure the AC output switch is turned on. The same applies to DC output ports.2.If the AC or DC power switch is on but charging is still not working, check if the DELTA Pro's output power matches your device's power requirements.3.If your device's power is below 10W, the AC output switch will turn off after 12 hours because the detected power is considered negligible. In this case, manually turn the AC output switch back on.4.If the screen displays an overload warning, the charging power is too high. Try the following: Turn off and let it cool for a while. Use a lower-power device. If the overload persists, power off and cool the unit for 30 minutes before restarting. If the issue continues, contact customer support.
Is the DELTA Pro compatible with the Smart Home Panel 2?
Yes, but you need a Double Voltage Hub to connect to the Smart Home Panel 2's 5+8 ports.
Can I use a DELTA Pro unit instead of a DELTA Pro Smart Extra Battery to connect to another DELTA Pro? If I want to connect two DELTA Pro units, what do you recommend?
No, the main unit must work with an Extra Battery for capacity expansion.If you want to connect two DELTA Pro units, consider using a Double Voltage Hub based on your actual needs.
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 I 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.
Can I run a 240V device on the 120V US version?
You'll need to connect two DELTA Pro units to power 240V electronics. You can do this by: 1) the Double Voltage Hub and use the AC outlets on the hub, or 2) the Smart Home Panel and use your home's 240V outlets (you'll need to setup 240V wiring on the Smart Home Panel during installation).
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.
Which portable power station is compatible with the DELTA Pro Smart Extra Battery?
DELTA Pro is compatible with the DELTA Pro Smart Extra Battery.
How many extra batteries can I use with a portable power station?
DELTA Pro supports 2 extra batteries.
Can I charge the extra battery without connecting to a power station?
Yes. You can use a Smart Generator to charge an extra battery even when it's not plugged into a power station. All other charging methods require it to be connected to a power station.
What makes the Smart Extra Battery "Smart"?
This battery can be monitored and controlled on the EcoFlow app.
