SOLAR PANEL CONNECTION

How to recharge the EF DELTA with solar panels?
If you need to know more about the connection of a single panel, please refer to Solar Panel User Manual. Here we focus on demonstrate how serial connection (up to three panels and the parallel connection of up to six panels). EF DELTA supports 10-65V DC input. When the input exceeds 65V, EF DELTA overload protection will be triggered. Voltage excessive may damage the product. Users should follow all the instructions in the manual. EcoFlow do not provide free repair services for any product damage caused by connecting many solar panels to the product or incorrect connection, even during the warranty period.

Recommended serial connection method

a. Users can connect 1 to 3 pieces of solar panels (do not connect more than 3 in series) in series as shown in the figure below, to the MC4 port.
b. Then, connect to MC4 to XT60 conversion cable.
c. Use XT60 conversion port connect to the XT60 port on EF DELTA.

Serial and parallel connection (Professional solution)
Users can connect up to 2 sets of solar panels in parallel to the MC4 port as shown in the figure. If you want to connect 6 solar panels, you can put them into 2 sets of 3 solar panels connected in series and then 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 needs to be purchased separately.

EF DELTA supports the use of third party solar panels (DIY solution)

Users can buy universal solar panels of MC4 connection standard on their own 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.
Note : EcoFlow do not provide free repair services for any damage to the product caused by the quality issue or improper operation of the third-party solar panels, even in the warranty period.

ENTRY-LEVEL UPS AND SERIES MODE

Precautions when using EF DELTA UPS and series mode

When EF DELTA has UPS or series mode on, EF DELTA’s X-STREAM system supports an entry-level UPS function. 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 suddenly loses power, the device can automatically switch to EF DELTA battery power mode in <=30ms to ensure your work is not interrupted. Series mode is a multi-level power series solution developed based on the UPS function.

It allows users to connect two EF DELTAs in series to get continuous power that is two times more than a single machine. The principle of using it is when the power of a EF DELTA is used up, the next machine can immediately replace it to continue the power supply. This a entry-level UPS function that does not support 0ms in switching power. Do not connect devices require high continuing power supply. Otherwise, please run multiple tests to confirm it’s compatibility before connecting devices, such as data servers and workstations, with EF DELTA. EcoFlow do not take responsibility for any data loss or equipment damage caused by customers’ failure in following the instruction.

1. Entry-Level UPS user guide
   Users can connect the EF DELTA AC charging cable to the power grid and connect a electricity device to EF DELTA turn on the AC switch and automatically enter the entry-level UPS mode. When the external power is cut off, battery will immediately supplied power to protect your device.
   EF DELTA supports the entry-level UPS function with the switching time of less than 30ms. In accordance with the UL 2743 standard, the AC output consist of a double blade, ungrounded configuration. Hence, it is recommended to use the UPS function of EF DELTA only for temporary emergency usage rather than for long-term usage. DO NOT use electric appliances with bare metal when charging to avoid the risk of electric leakage and electric shock. It is recommended NOT to use the UPS function of EF DELTA for products such as databases, servers, etc. If you want to use the UPS function for devices that is sensitive to the switching time, please purchase a professional-grade UPS system. Please note that EcoFlow is not responsible for any potential data loss due to the use of UPS function.

2. Series mode user guide (Recommended for power users; all machines must be fully charged)
   Users can connect no more than 2 fully-charged EF DELTAs in series using the AC charging cable 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. Connect EF DELTA to a home power grid and charge each EF DELTA separately. We do not recommend you to charge more than two EF DELTA at the same time. Otherwise, the excessive load may cause damage to the home power grid. To use this function, you need to set one EF DELTA as the Master and the others as Serve 1. Connect one AC cable to the AC output port of the master unit and the other side to the input port of Serve 1. After connecting the EF DELTA, turn all the AC switches on EF DELTA on to activate multi- machine series mode. Finally, connect all the appliances to the AC sockets of the Serve 1. Then you can charge your devices by using EF DELTA and enjoy the benefits from extended powering time.

HOW TO RECHARGE EF DELTA

Example 1:

Example 2:
We reommend you to start the car before connect car charger to EF DELTA.

How do I recharge my EF DELTA?
EF DELTA has an AC charging port and a XT60 charging port located on the side of EF DELTA. EF DELTA can be charged through AC power or solar panel. Besides, you can also use solar panels connect in series (no more than three) and connect the solar charge cable to the XT60 solar charging port of EF DELTA for charging.

Can EF DELTA power my devices while it’s charging?
Yes, EF DELTA can be charging and outputing power in the same time. When you are charging EF DELTA, we do not recommend connecting an electrical appliance with a power over 800w for discharging, because the current capacity of the wall outlet is limited.

FAQs

How do I care for EF DELTA?
EF DELTA is designed for various uses. If you need to clean EF DELTA, please use a dry and non-abrasive cloth to clean the surface. You can use cleaners designed for mobile phones or computer screeens can to clean EF DELTA, but do not give it a bath!

How do I store EF DELTA?

1. EcoFlow offers a water-resistant, dustproof case and we recommend you to use it when you plan to store your EF DELTA for a long time.
2. Make sure to recharge EF DELTA to around 85%.
3. Put EF DELTA into the case
4. Please store your EF DELTA in a dry environment without surrounded by abrasive objects. For optimal battery health, store EF DELTA in room temperature.
5. Discharge EF DELTA to 30%, then charge to 85% every 3 month. This can help prolong the battery life and ensure your EF DELTA is ready to recharge the gears at all times. Without any external sources for power supply during storage, EF DELTA has a shelf life of over a year.

How do I use EF DELTA safely?
Please use EF DELTA in its operating temperature range. Using EF DELTA outside of its optimal operating temperature range can push the machine beyond its safe and eective limits. Do not submerge your EF DELTA in water. It is not waterproofed and this will void your warranty. If you want to protect EF DELTA against moisture and dust, use a EF DELTA protector (IP54). Do not block the ventilation Fan while using EF DELTA.

WARNING : Do not charge the machine right after it is fully discharged (E.g. 1000W keep 40mins or 1500W keep 30 mins). For your safety, please wait 2 to 3 hours for the product to cool down before charging it! If you attempt to charge EF DELTA immediately after a full discharge, EF DELTA will display as an overheating protection reminder. Please wait 2 to 3 hours for the machine to be cooled down before recharging it.
