FAQ

What's the maximum solar input that the EcoFlow Delta 3 can support?

EcoFlow DELTA Pro 3 has two PV input ports, which are for high-voltage PV port and low-voltage PV, respectively. High-voltage PV: 30-150V, 15A Max, 1600W Max. Low-voltage PV: 11-60V, 20A Max, 1000W Max.The maximum solar input for the EcoFlow DELTA Pro 3 is 2600W. Please note that this value is based on experimental results under optimal conditions. Achieving this maximum input may require the use of higher-power solar panels that are within the product’s voltage tolerance but exceed the PV port’s power limit. Actual solar input performance can vary depending on the solar panels used, environmental factors, and system configuration. For more information on designing your own solar setup, please contact EcoFlow Customer Service. Before performing any installation, please ensure that it is carried out by a qualified and certified professional.

Can I directly connect EcoFlow power stations to my house electric panel?

Yes, connecting EcoFlow power stations to your house electric panel is possible, but there are important considerations to keep in mind:

  • Connect the transfer switch to the power station's AC output port.
  • Ensure circuits are disconnected from the grid before being supported by the power station.
  • Be mindful that the total power consumption of the circuits should not surpass the output power rating.
  • Note that if the power station isn’t connected to the grid, the output won’t be grounded.

Is it possible to connect multiple power stations together in series?

Yes. We advise connecting a maximum of two identical units in series. Additionally, please keep in mind:

  1. Ensure the slave unit is fully charged before connecting.
  2. Do not charge the main unit when the slave unit is connected.

Do portable solar panels work?

Portable solar panels are a highly effective, eco-friendly, and renewable method to charge a portable power station. EcoFlow 400W portable solar panels have higher wattage compared to standard ones and boast greater efficiency, thanks to their monocrystalline cells. You can set up to three 400W portable solar panels and pair them with a DELTA Pro portable power station, providing an input of 1600W. Moreover, EcoFlow portable power stations use an MPPT algorithm to ensure a consistent energy supply. Unlike fixed solar panels, portable ones can be easily moved and adjusted according to the sun's position in the sky.

How much power can the 220W solar panel generate in regular conditions?

It mainly depends on the weather. Generally, on a clear, cloudless day when sunlight hits the panel at a 90° angle, it typically produces between 160W and 180W of power. Under test conditions, the current light levels usually range between 74.3W–83.6W/ft2, with a panel temperature of 122°F. The panel's nominal power ratings are based on 92.9W/ft2 in AM1.5 conditions, with a panel temperature of 77°F under test conditions. Power outputs near nominal values were typically observed during midday in the winter sun.

Can I connect solar panels in parallel?

Absolutely! When you connect solar panels in parallel, you effectively double the current and enhance the overall power output. Check the specifications of your solar controllers and energy storage devices to confirm they can handle higher input current, which will help determine how many solar panels can be connected in parallel. Also, it's crucial to choose the appropriate wire diameter that can safely accommodate the change in output current.
