Solar compatibility

Solar panels for the EcoFlow DELTA Pro Ultra

It takes any panel between 30 V and 450 V through its MC4 / Proprietary inputs (2 of them), up to 5600 W, which refills it in about 1.1 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.

The best solar panel for the DELTA Pro Ultra

Picked by the numbers on this station, not by brand.

Best overall

Anker SOLIX 440W Rigid Solar Panel

13 panels deliver 4118 W, and it plugs straight in.

Best value

Eco-Worthy 195W N-Type 18BB Bifacial Solar Panel (GW-L02M195NTM)

About $1.00 for every watt it actually delivers here. 22 panels deliver 3088 W.

Best to carry

Jackery SolarSaga 500 X (JS-500A)

360 W from a 23.15 lb panel, the most delivered watts per pound.

Other solar panels compatible with the DELTA Pro Ultra

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, 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 take to charge on solar?

At its 5600 W solar limit it refills in about 1.1 hours. More panel watts than that won't charge it any faster.

What adapter does the DELTA Pro Ultra need for solar?

None, if the panel's plug is MC4 or Proprietary: BLUETTI 350W, Anker SOLIX 440W Rigid, BLUETTI PV100 FX Flexible 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?

Yes. What decides it is the panel's voltage and plug, not the brand. 22 panels from Renogy, Jackery, BLUETTI, Anker SOLIX, Eco-Worthy and Rich Solar work with it, as long as the panel stays under 450 V on a cold morning and starts above 30 V.

The strongest single panels here are the Renogy 590W N-Type Bifacial (425 W delivered) and the Jackery SolarSaga 500 X (360 W delivered).

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

You have to. Its input starts at 30 V, so one panel alone won't wake it: wire 2 or more in series.

Wired in series, up to 9 BLUETTI PV100 FX Flexible panels fit under its 450 V limit, even on a -10°C morning. Series adds voltage; parallel adds current.

Past 5600 W delivered, more panels only help on cloudy days.

What is the DELTA Pro Ultra's solar input?

High-PV Input (high-PV input port, on the inverter): 80–450 V, up to 15 A, 4000 W. Low-PV Input (low-PV input port, on the inverter): 30–150 V, up to 15 A, 1600 W. 5600 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.
