Solar panels for the EcoFlow DELTA 2

It takes any panel between 11 V and 60 V through its input, up to 500 W, which refills it in about 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 2

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 2, 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 2 take to charge on solar?

One 100 W panel delivers about 72 W in good sun and refills the 1024 Wh battery from empty in about 14.2 hours.

One 200 W panel delivers about 144 W in good sun and refills the 1024 Wh battery from empty in about 7.1 hours.

At its 500 W solar limit it refills in about 2 hours. More panel watts than that won't charge it any faster.

A day gives three to six hours of sun that good, depending on season and place, so one 100 W panel takes 3 to 5 days to fill it. The system builder works it out for your state and month.

What adapter does the DELTA 2 need for solar?

Every panel we track needs a cable to reach its input. None comes in the box.

29 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 2?

Yes. What decides it is the panel's voltage and plug, not the brand. 22 panels from Renogy, Jackery, Anker SOLIX, BLUETTI, Eco-Worthy and Rich Solar work with it, as long as the panel stays under 60 V on a cold morning and starts above 11 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 2?

Yes, joined into one input with a series or parallel cable.

Don't wire two BLUETTI PV100 FX Flexible panels in series: together they would pass its 60 V limit. Parallel them instead.

Past 500 W delivered, more panels only help on cloudy days.

What is the DELTA 2's solar input?

Solar/car charging input port (spec row: "Solar Charging"): 11–60 V, up to 15 A, 500 W.

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