FAQ

Delta Pro

Can EcoFlow power stations be charged by solar panels and the 12V car cigarette lighter at the same time? (For all power stations)

No, this is because the car charging and solar charging cables share the same input (XT60 outlet).

Notes on X-boost (Delta Pro)

This product has X-Boost enabled by default. You can use the EcoFlow app to turn this function on or off.

X-Boost is not available in the following situations:

(1) the AC output is turned on in the charging state (in bypass mode) and (2) the X-Boost mode is turned off.

X-Boost is more suitable for heating and electrical equipment, but not for all electrical appliances. Some electrical appliances equipped with voltage protection (such as precision instruments, etc.) are not suitable for X-Boost.

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 taken 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.

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 supports 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 conducting 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.

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.
