What's In The Box?
Yes, EcoFlow DELTA Pro 3 can be connected to EcoFlow Smart Home Panel 2 through the power input/output port.
Yes, EcoFlow DELTA Pro 3 can be connected to the EcoFlow 50 Amp Hub dedicated for EcoFlow DELTA Pro Ultra via the AC Power IN/OUT port, supporting the parallel connection of up to 2 sets of EcoFlow DELTA Pro 3.
EcoFlow DELTA Pro 3 has two PV input ports, which are for high-voltage PV port and low-voltage PV, respectively.High-voltage PV: 30-150V, 15A Max, 1600W Max. Low-voltage PV: 11-60V, 20A Max, 1000W Max.The maximum solar input for the EcoFlow DELTA Pro 3 is 2600W. Please note that this value is based on experimental results under optimal conditions. Achieving this maximum input may require the use of higher-power solar panels that are within the product’s voltage tolerance but exceed the PV port’s power limit. Actual solar input performance can vary depending on the solar panels used, environmental factors, and system configuration. For more information on designing your own solar setup, please contact EcoFlow Customer Service. Before performing any installation, please ensure that it is carried out by a qualified and certified professional.
When the device is powered off, press and hold the power button for more than 5 seconds. The device's LCD screen will light up, and then the screen will blink once (it must blink once), indicating that the Bluetooth connection has been successfully reset.
Yes, it supports Level 1/2 EV chargers. You will need to purchase a dedicated EcoFlow adapter, the EV X-Stream Adapter (DELTA Pro Ultra). Typyically, the grid charging port on the US model only supports AC 120V 2000W charging (Level 1). However, by using the AC POWER IN/OUT port along with the EV X-Stream Adapter (DELTA Pro Ultra), you can connect a 240V EV charger, increasing the charging rate to 4000W (Level 2).
No, but it can perform split-phase output as a standalone unit.There are two buttons for AC output: 120V AC ON/OFF and 240V AC ON/OFF.1. When the 120V AC button is pressed, four 120V 20A outlets and one 30A RV outlet will supply power, and the 240V outlet will be turned off.2. When the 240V AC button is pressed, one L14-30 split-phase outlet and one 6-20R 240V outlet output power, and the 120V outlet will be turned off.
Yes, it will.However, there are specific requirements for the light conditions. In weak lighting environments, it might not trigger the device to power on.

As the core component of the device, the safety and protection level of the battery pack is crucial. To better protect the battery pack and reduce the risk of short circuits and fires caused by water ingress, the EcoFlow DELTA Pro 3 battery pack is sealed. It has reached an IP65 waterproof and dustproof rating, effectively preventing dust from entering and resisting water spray.However, the EcoFlow DELTA Pro 3 main unit does not have a waterproof and dustproof rating (IP20). The device is suitable for use in well-ventilated indoor environments or sheltered outdoor environments to avoid the impact of rain and dust on the device. Please ensure that the surrounding environment is dry and clean during installation and use to ensure the device's normal operation and longevity.
EcoFlow DELTA Pro 3 is equipped with an internal GFCI ground circuit. Users can connect an external GFCI protector according to their needs. When an external GFCI protector is connected to EcoFlow DELTA Pro 3, the GFCI support switch must be turned on in the app for the external GFCI protector to function properly.
