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: 15h-30h
b. 2x 110W solar panel (in series): 7.5h-15h
c. 3x 110W solar panel (in series): 5h-10h
d. 4x 110W solar panel (in parallel): <4h
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

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
Most Tesla models (Model X, the new version of Model S, Model 3) can be charged by DELTA, except Model S.
In order to meet the UL2743 standard, DELTA's sockets are not grounded. We have tests for hundreds of times on different devices. We found Tesla needs a grounded cable, however, other electric vehicles and equipment with grounded chargers can all be charged by DELTA properly.
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 60%. However, the lifespan of a battery depending on how it is used, maintained, etc.
Please keep your DELTA connected to a power source (solar panel or wall socket) to help prolong the battery life and ensure your DELTA is charged and ready for use anytime. If you cannot keep your DELTA connected to a power source during storage, please fully charge and discharge the battery at least once every 3 months to maintain the battery health. Also store your DELTA in a cool, dry place.
EcoFlow's warranty does not cover any damage cause by third-party solar panels or accessories.
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.
Yes, you can! If your house is not off-grid, please cut off the connection between power grid and your house before powering your house using DELTA.
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.
