Theoretically speaking, you can connect as many DELTAs in serial (but not in parallel) as you want. However, the efficiency of the machines will be seriously compromised (The energy consumption of the inverters grows with the number of the connected machines). As a result, we do not recommend to connect more than 3 DELTAs in serial, and it is necessary to fully charge every DELTA before you connect them together. Moreover, connecting DELTA in serial will not increase the rated output, but will expand the capacity.
DELTA can be recharged through your car port and power your devices simultaneously.
When DELTA is charged through the AC and DC port at the same time, it will prioritize taking in power through the AC port. After you plucked out the AC cable, DELTA will start taking in electricity through the DC port.
DELTA can be recharged to 0%~80% in 1 hour, and be fully recharged in 1 hour 40 minutes.
DELTA can be fully charged through a 13.6V car port in 10-12 hours.
At perfect sunlight:
a. 1x 110W solar panel: 14-28 hrs
b. 2x 110W solar panel (in series): 7-14 hrs
c. 3x 110W solar panel (in series): 5-10 hrs
d. 4x 110W solar panel: 4-8 hrs
DELTA supports solar input ranges from 10V to 65V with a maximum allowed current of 10A and maximum input of 400W.
In the Noise Test Chamber
1. Noise Tester: TES-1357
2. Ambient noise: 33.8dB
3. Test outcome: the average outcome from the front, back, right, and left
Condition 1: AC outlet: <500W; the fan: 10% full speed, <40DB, 2-meter distance; Condition 2: AC outlet: 500W-1200W; the fan: 30% full speed, <45DB, 2-meter distance;
Condition 3: AC outlet: >1200W; the fan: 100% full speed, <50DB, 2-meter distance
Discharge Temperature Range: -4-113°F (-20-45°C)
Recharge Temperature Range: 32-113°F (0-45°C)
When the ambient temperature is above 113F or below -4F, the high temperature or low temperature warning icon on DELTA's screen will light up and flash correspondingly. At the same time the battery management system (BMS) will regulate the input and output of power to protect DELTA.
If you want to charge your DELTA in low
temperature environment (between -20°C – 0°C) please use your DELTA to power an electronic with a voltage over 500W for over 10 minutes to warm up DELTA before charging it.
After 800 Cycles of use, DELTA's capacity will drop to 80%. However, the lifespan of a battery depending on how it is used, maintained, etc.
Please use and store the device according to the following environment temperatures:
Normal use and storage: -4 to 113°F (-20 to 45°C)
Optimal use and storage: -4 to 77°F (20 to 25°C)
Cold weather use
Cold temperatures (below freezing) can affect the unit's battery capacity due to chemical characteristics of the battery. Keep the power station within the environment temperature range, -4 to 113°F (20 to 45°C) to prolong battery life.
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.
DELTA can be charged by Ecoflow solar panels when the open-circuit voltage is between 10V and 65V. You can connect up to 3 EcoFlow solar panels in series. You can also connect 2 sets of 3 solar panels connected in series in parallel (up to 6 panels). The parallel connection cable is an optional accessory that needs to be purchased separately.
You cannot use DELTA to jumpstart your car, because the current needed for jumpstarting a car is higher than 20An (DELTA's car port can only allow a maximum current of 8An).
DELTA can charge the lead batteries of your car through the car charge cable included in your DELTA parcel.
You can use MC4-XT60 cable to recharge your DELTA. This type of cable come with the box.
DELTA can charge Tesla around 40 minutes. After charging by DELTA you can drive your Tesla for 3-5miles. However, the mileage that can be lasted after one charge by DELTA varies, it is depends on the types of EVs you are driving and the ambient temperatures.
DELTA 1000 and DELTA 1300 are equipped with the same number of battery cells, but battery cells of different energy densities are used.
DELTA's AC ports support pure sine wave. As a result, when you plug your electronics in DELTA, they are well-protected with less generated electrical noise and longer-lasting motors.
DELTA supports an entry-level UPS function. But please perform multiple tests to confirm compatibility before connecting such devices as data servers and workstations with DELTA. EcoFlow will not be responsible for any loss of data or equipment damage caused by customers’ failure in following the instructions.
The solar panels are IP67 rated so they can still function in the rain but the performances of the panels depend on how much sunlight is available. You can rest the solar panels on the car roof, the boat roof and the roof of your house for efficient and convenient solar power (You can purchase EcoFlow's suction cups separately to help attach the panels to flat surfaces).
DELTA is equipped with the EcoFlow patented fast-tracking MPPT controller, which is supported by EcoFlow's unique tracking algorithm. This algorithm helps maximize the solar input under any weather condition. DELTA supports any solar input ranges from 10V to 65V with a maximum allowed current of 10A and a maximum input of 400W. You can chain your solar panels in series or in parallel to maximize the solar input.
Yes. RIVER can power devices up to 1800W with our proprietary technology, X-Boost. *X-Boost can run devices that require up to 1800W, however, it’s best to test before use. Some 600W-1800W appliances with strict voltage requirements may not function (eg. air compressors).
Yes. You can control RIVER using your phone. Just link to it in the EcoFlow app to control it from afar.
It can be an emergency power source (EPS), which will have the same result as UPS for most electronics. Here's the difference.When your RIVER is plugged into the wall, anything plugged into it gets power from the grid, not its battery. If power from the grid stops, RIVER automatically switches to its battery supply mode within 30 milliseconds. That means anything connected will not have power for 30 milliseconds, which may mean sensitive electronics like desktop computers and data servers turn off. Test your devices individually to see if they need UPS to stay powered.
RIVER supports entry-level UPS functionality. Make sure to perform multiple tests to confirm compatibility before connecting devices such as data servers and workstations with RIVER.
No. The flashing icon only indicates that the component is being upgraded.
When the screen is off, the light will automatically go off instantly; if you need to use the ambient light continuously, please make sure that your screen standby time has been set to "Never" or select the ambient light to the "Night light" mode.
Each of the RIVER Series has its advantages. RIVER is ideal for lightweight, grab-and-go power, which you can expand with the extra battery. RIVER Max includes the extra battery by default, which you can remove to go lightweight. RIVER Pro is made for those that need even more capacity for off-grid, long haul adventures.
They’re made from monocrystalline silicon which is more efficient than polycrystalline. New materials like EVA and ETFE protect against high temperatures, corrosion, sunlight, as well as damage, which ensures that they can be used outdoors for long periods. They have a waterproof rating of IP67 and are also resistant to dust and UV rays.

Yes, if they (1) can connect via an MC4 connector and (2) can support the amperage, voltage, and wattage that an EcoFlow solar panel outputs.
Yes, if the solar panel (1) has MC4 connectors and (2) has an output amperage, voltage, and wattage that the EcoFlow portable power station can support.
When storing the solar panels, be careful to fold the solar panels and then put them in the bag with the junction box and wiring harness facing upward.
Charging power is affected by the strength and angle of the light. To increase output power, choose a time of day when the sunlight is strongest (hours around noon), and keep the solar panel positioned 90° to the sun. Try not to use the solar panel on cloudy days or in shaded areas.
