  • How long does it take for DELTA to get fully charged by 110W Solar Panel?
  • DELTA supports solar input ranges from 10V to 65V with a maximum allowed current of 10A and maximum input of 400W. At perfect sunlight it takes:

    1. 1x 110W solar panel: 16h-32h
    2. 2x 110W solar panel (in series): 7.5h-15h
    3. 3x 110W solar panel (in series): 5h-10h
    4. 4x 110W solar panel (in parallel): <4h
  • Can I charge my DELTA through the DC and AC port at the same time?
  • Yes, and 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, EFDELTA will start taking in electricity through the DC port.

  • What is the charging time when DELTA is charged by an AC cable?
  • DELTA can be recharged to 0%~80% in 1 hour, and be fully recharged in 1 hour 40 minutes.

  • Can I use DELTA to charge my devices while it is charged through the car port?
  • DELTA can be recharged through your car port and power your devices simultaneously.

  • What is the waterproof level of EcoFlow Solar Panels?
  • 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).

  • Can DELTA be used inline as an UPS for uninterrupted power?
  • 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.

  • Do the AC ports support pure sine wave or modified sine?
  • 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.

  • Is DELTA equipped with a MPPT controller?
  • 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.

  • Can DELTA Charge EV?
  • DELTA support charging most of the models from Tesla (Model X, the new version of Model S, Model 3) except the old version of Model S.

    *Please note: In order to meet the UL2743 standard, DELTA's sockets are not grounded. However, after conducted hundreds of tests on different electronic vehicles, the results is that only Tesla needs a grounded cable, others with grounded chargers can all be charged by EF DELTA properly.

  • What is the Noise level of DELTA?
  • In the Noise Test Chamber

    Test condition:

    1. Noise Tester: TES-1357
    2. Ambient noise: 33.8dB
    3. Test outcome: the average outcome from the front, back, right, and left

    Test results:

    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

  • Can I use DELTA for my off-grid house?
  • 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.

  • Which type of cables can be used to connect solar panels to DELTA?
  • The cable that can be used to recharge your DELTA by solar panels is MC4 to XT60 cable, and this cable is included in the packaging of DELTA.

  • Can I charge DELTA series power stations with RIVER series power station AC charging cables?
  • DO NOT use RIVER series portable power station AC charging cables on DELTA series power stations. EcoFlow takes no responsibilities for any damages caused by customers' failure to follow instructions. Doing so will void the warranty.
