Solar panels for the EcoFlow DELTA Pro Ultra X

It takes any panel between 80 V and 500 V through its MC4 inputs (2 of them), up to 10000 W, which refills it in about 1.2 hours of good sun. 29 of the 39 panels we track work; none are over the limit.

Its input window, and where each panel lands

Each line is one panel's open-circuit voltage. Inside the band it can connect on its own; in the red, never plug it in.

Other solar panels compatible with the DELTA Pro Ultra X

Any brand, checked by the numbers: voltage on a -10°C morning, current, and the plug. Most delivered watts first.

Already own a panel that isn't listed?

Type the numbers from the label on its back into the panel checker, already set to the DELTA Pro Ultra X, or build the whole system to see how it keeps up where you live.

10 panels we track get no verdict because their makers don't publish an open-circuit voltage.

How long does the DELTA Pro Ultra X take to charge on solar?

At its 10000 W solar limit it refills in about 1.2 hours. More panel watts than that won't charge it any faster.

What adapter does the DELTA Pro Ultra X need for solar?

None, if the panel's plug is MC4: Anker SOLIX 440W Rigid, BLUETTI PV100 FX Flexible, BLUETTI SP100L and 7 others plug straight in.

The cables the other panels need: DC8020 to MC4 (4 panels), Anderson to MC4 (3 panels), DC5521 to MC4 (2 panels) and XT60 to MC4 (1 panel).

9 panels don't have a named plug from their maker, so check the lead before you buy a cable.

Can you use non-EcoFlow solar panels with the DELTA Pro Ultra X?

Yes. What decides it is the panel's voltage and plug, not the brand. 22 panels from Anker SOLIX, BLUETTI, Eco-Worthy, Jackery, Renogy and Rich Solar work with it, as long as the panel stays under 500 V on a cold morning and starts above 80 V.

No single panel starts it; they go in series. The strongest setups here are 22 Anker SOLIX 440W Rigid panels (6970 W delivered) and 16 Renogy 590W N-Type Bifacial panels (6796 W delivered).

Can you connect two solar panels to the DELTA Pro Ultra X?

You have to. Its input starts at 80 V, so one panel alone won't wake it: wire 3 or more in series.

Wired in series, up to 10 BLUETTI PV100 FX Flexible panels fit under its 500 V limit, even on a -10°C morning. Series adds voltage; parallel adds current.

Past 10000 W delivered, more panels only help on cloudy days.

What is the DELTA Pro Ultra X's solar input?

PV input port 1 (PV circuit one): 80–500 V, up to 15 A, 5000 W. PV input port 2 (PV circuit two): 80–500 V, up to 15 A, 5000 W. 10000 W across all inputs together.

Input limits from EcoFlow's documents, checked 2026-09-18 (source). Delivered watts assume 72% of the panel's rating in good sun.
