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 connected machines).  

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 prioritise 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.

Most Tesla models (Model X, the new version of Model S, Model 3) can be charged by DELTA, except Model S.

Discharge Temperature Range: -4-113°F (-20-45°C)

After 800 cycles of use, DELTA's capacity will drop to 60%. However, the lifespan of a battery depends 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. 

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). 

You can use MC4-XT60 cable to recharge your DELTA. This type of cable comes with the box.

DELTA can charge Tesla around 40 minutes. After charging by DELTA you can drive your Tesla for 3-5 miles. However, the mileage that can be lasted after one charge by DELTA varies, it depends on the types of EVs you are driving and the ambient temperatures.

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 maximise 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 maximise the solar input.
