Charge Computers or other devices requiring USB C charging ports. When the USB-C port is in use the
indicator will light up.
3. USB-C Output Ports
These ports have a higher power output that the regular USA-A ports and will charge devices at twice the
rate.
5. Fast Charge USB-A Output Ports
Press and hold the main power button to switch the Delta on or o. When the Delta is turned on the LCD
display screen will light up. After a period of time (usually 5 minutes) the display screen will enter idle mode
and switch itself o to conserve power. This doesn’t turn o the internal battery and the Delta is still
working. To wake up the display screen briefly press the on/o button and the screen will come to life. The
power indicator light will light up when the Delta senses any of its ports come into use, e.g. a device is
plugged into any of the output ports. If the Delta is left idle with nothing plugged into any of the output
ports for an extended period of time it will switch itself o completely to conserve battery life.
6. Main Power On/O Button
The AC Power Button regulates the flow of AC output from the Delta. Please press and hold the AC button
to enable or disable the flow of AC power. The AC indicator light will be on when the AC power is active but
will turno after 12 hours in idle mode. The output is pure sine wave AC power very closely matching the AC
power output from regular Australian/New Zealand mains power household outlets. It is therefore lethal if
not used correctly and it is essential that users take all the same precautions when using this AC power as
they normally would in a household environment. The Delta uses a power inverter to produce the AC power
and this device consumes battery power just to operate in idle once switched on. It is therefore sensible to
conserve battery life by switching o the AC power and unplugging any AC power cords when AC power is
not required.
7. AC On/O Switch - (Press and Hold for ON/OFF) AC Output Indicator Light
The Delta produces heat internally as it operates to supply power. The Delta fans cool the internal
components including the battery pack by circulating air to prevent overheating. The Delta fans will
operate at dierent speed levels depending on the environmental conditions and the power output load
that the Delta is producing. You will note that the fans are always in operation when the AC power is
activated. This is one of the reasons that the AC power should be turned o when not needed, as this will
prolong battery life.
8. Ventilation Fan Vents (DO NOT Block or inhibit airflow in any way)
These outlets should be used with care and respect. The Delta is capable of producing up to 1800w of AC
power on a continuous basis and higher surge loads for short periods of time. This level of power is
sucient to power many appliances and power tools. This makes Delta a very useful and flexible source of
portable AC power. It does however have design limitations. The Delta may not power certain appliances

First Press and hold the Power Button (6.) to turn on the Delta unit and then press and hold the DC power
button to turn on the DC power. When finished press and hold the DC button to turn o the DC power. In
certain cases devices may have a very low power draw. In this case the DC power may sleep as it detects a
lack of use. To ensure this doesn’t happen you can connect an another device to charge from to the USB
port and this will keep the Delta awake.

operation.
10. DC Output Outlet and Indicator.
DC Input from Solar or Car Cigarette Lighter DC Output. The Delta is designed to accept solar inputs of up to
10 amps and not exceeding 65 volts. The Delta has a power input limit of 400w. If you are using the Delta
110w panels, up to 3 panels may be connected in series. It is absolutely essential that the positive and
negative connections from the panel to the Delta charging cable are correctly made. Reverse polarity will
case damage to the DC power input electronics and this is not covered by warranty. If in any doubt, please
seek support from a qualified electrician to ensure damage does not occur. This DC Charging port can also be
used to charge the Delta from a vehicle cigarette lighter DC power outlet of a maximum of 10 amps.
11. DC Input (Charging) Port.
Connect the Delta AC charging cable to this Delta AC input port and the plug to an Australian 240v 50HZ
mains power outlet and the Delta will commence charging. The Delta is capable of charging quickly and will
set the charge rate based on the temperature and state of charge of the internal battery pack. If the Delta
has recently been discharged under high load for an extended period of time the charging function will be
disabled until the internal battery pack returns to a normal temperature. If the Delta will not charge this is
not a defect it is a safety feature, wait until the internal battery pack returns to room temperature and try
again.
12. 3 Pin AC Input (Charging) Port.
The Delta has an entry –level UPS function, so that you can use the Delta as a backup with you household
or portable computer. If the computer is plugged into the Delta while the Delta is plugged into the mains
power it will automatically change from pass-through mode to battery mode should the mains power be
interrupted. The cutover time is approximately 50ms. This is not as quick a cut over time as dedicated UPS
systems and please note that the Delta does not support systems requiring 0ms response times so if this is
the level of uninterrupted power that your computer system requires please don’t use the Delta for this
purpose.
13. Overload Protection/Reset Switch
that have very large start up power loads. This is not a design defect and the Delta will go into overload
protection mode. To reset the Delta disconnect the power cord. DO NOT exceed the 1800w limit by
plugging in Devices that require more than 1800w just to “test” the Delta. Damaged caused by overloading
the Delta is mistreatment and will void the warranty.

For connection of a single panel, please refer to the instructions of the solar panel. These instructions are
intended for the serial connection of up to three panels and the parallel connection of up to six panels. EF
DELTA accepts DC input of 10-65V. When the input exceeds 65V, EF DELTA will trigger overload protec-
tion. Excessive voltage may cause damage to the product and will void the warranty. Users should follow
all the instructions in the manual, if the number or connection of the solar panels is not compliant with the
specifications, we will not be responsible for providing free repair services for any damage to the product
even during the warranty period.
How to recharge the EF DELTA using solar panels?
Users can connect 1-3 pieces of solar panels (Up to a maximum of 3 panels) in series as shown in the
following picture. Connect one end of the panels to the MC4 port and connect the other end to our MC4 to
XT60 conversion cable. Connect the XT60 cable to the EF DELTA’s XT60 input to charge the device.
1. Serial connection (Recommended)
Users can connect up to 2 sets of solar panels in parallel to the MC4 port as shown in the picture. If you
want to connect 6 solar panels, you can split -them into 2 sets of 3 solar panels connected in series and
connect the 2 sets of solar panels in parallel. Connect them with our MC4 to XT60 conversion cable and
connect XT60 cable to the EF DELTA’s XT60 input to charge the device. The parallel connection cable is an
optional accessory that needs to be purchased separately.

Users can buy universal solar panels with MC4 connections to power EF DELTA, as long as the voltage and
current (10-65V DC, 10A max) comply with the specifications of EF DELTA, the panels will be able to
recharge EF DELTA through the MC4 to XT60 conversion cable. However, EcoFlow will not be responsible
for providing free repair services for any damage to the product caused by the quality issue or improper
operation of the third party solar panels, even during the warranty period. It is essential that users check the
positive and negative connections are correct. Reverse polarity connections are a common mistake, will
damage the Delta and will not be covered by the warranty.
3. EF DELTA supports the use of third party solar panels (DIY solution)
When EF DELTA is used under UPS or multi-machine series mode, EF DELTA's X-STREAM system supports
an entry-level UPS (Uninterruptible Power Supply) function, and you can use the EF DELTA AC socket
while the device is connected to a wall socket with AC power supply (The AC power comes from the grid,
not the battery). When the grid loses power suddenly, the device can automatically switch to EF DELTA
battery power mode in <50ms to ensure your work is uninterrupted provided the needs of your computer
do not require a faster cutover speed. It the responsibility of the user to determine whether this cut over
time is sucient to ensure uninterrupted performance of their system.

Users can connect the AC charging cable of EF DELTA to the power grid and connect a device to EF
DELTA and turn on the AC switch to automatically enter the entry-level UPS mode. When the external
power is cut o, power will be supplied from the battery immediately to protect connected devices.
1.Entry-Level UPS User Guide
Note: (Before connecting multiple Delta’s together in this mode, All machines must be fully charged)
Users can connect multiple fully-charged EF DELTAs (Up to 3) in series using the AC charging cables to get
continuous power and supply appliances with high output requirements for up to 1.8 hours. In this mode, do
not connect EF DELTA to the power grid using an AC charging cable, or the overcurrent protection (<20A)
may be triggered. Before using this mode of operation connect each EF DELTA to a home power grid and
charge each EF DELTA separately. It is not recommended to charge more than two machines simultane-
ously from the same household power outlet. Otherwise, the excessive load may cause overload/damage
to the home power circuit. To use this function, you need to at first set any of the machines as the master
and the others as Slave 1 and Slave 2. Connect one end of the AC cable to the AC output port of the master
unit and the other end to the input port of Slave 1. Then, connect one end of the AC cable to the AC output
port of Slave 1 and the other end to the input port of Slave 2. After connecting the machines, turn all the AC
switches of the machines on to activate multi-machine series mode. Finally, connect all the appliances to
the AC sockets of the Slave 2 and then you can charge your devices using EF DELTA and enjoy the benefits
of extended powering time.
2 . Multi Machine Series Mode User Guide
Multi-Machines Series Mode is a multi-level power series solution developed based on the UPS function.
It allows users to connect multiple EF DELTAs in series to get continuous power that is multiple times of a
single machine. The principle of use is that when the power of an individual DELTA is used up, the next
DELTA can immediately replace it to ensure uninterrupted power supply. This a entry-level grade UPS
function that does not support 0ms switching.
Note: Do Not connect devices with high uninterrupted power supply requirements. Perform multiple
tests to confirm compatibility before connecting such devices as data servers and workstations with EF
DELTA. EcoFlow will not be responsible for any loss of data or equipment damage caused by customers’
failure to determine the suitability of Delta to support their UPS
