Solar panels for the EcoFlow DELTA 2 Max

It takes any panel between 11 V and 60 V through its inputs (2 of them), up to 1000 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 Max

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 Max, 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 Max take to charge on solar?

One 100 W panel delivers about 72 W in good sun and refills the 2048 Wh battery from empty in about 28.4 hours.

One 200 W panel delivers about 144 W in good sun and refills the 2048 Wh battery from empty in about 14.2 hours.

At its 1000 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 5 to 10 days to fill it. The system builder works it out for your state and month.

What adapter does the DELTA 2 Max 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 Max?

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 Max?

Yes. It has 2 solar inputs, so the simplest way is one panel on each. Use the same panel model on both. EcoFlow's inputs share a controller, and mismatched panels hold each other back.

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

Past 1000 W delivered, more panels only help on cloudy days.

What is the DELTA 2 Max's solar input?

Solar charging input (×2): 11–60 V, up to 15 A, 500 W. Solar charging input (×2): 11–60 V, up to 15 A, 500 W. 1000 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.
