Can I Use a Non-EcoFlow Solar Panel With My EcoFlow Power Station?

Yes, you can use a non-EcoFlow solar panel with an EcoFlow power station, as long as it passes three checks against the station’s solar input:

1. Its Voc (open-circuit voltage) stays at least 5% below the port’s maximum voltage.
2. Its Isc (short-circuit current) is no higher than the port’s current limit.
3. Its Vmp (operating voltage) is above the port’s minimum voltage.

Most third-party panels use MC4 plugs, so you will also need an MC4-to-XT60i adapter cable.

Step 1: Read the panel’s label

Find Voc, Isc and Vmp on the spec sticker or the maker’s datasheet. Use the manufacturer’s figures, not the marketplace title. A PowMr 150W flexible listing says “20.4V 9.5A”, for example, while PowMr’s own page gives Voc 21.6V and Isc 9.16A. If no Voc or Isc is published anywhere, stop here, because you can’t check that panel.

Step 2: Find your station’s solar input limits

These limits are from EcoFlow’s manuals:

Step 3: Do the maths

• One panel: compare its Voc and Isc directly.
• Series (plus to minus): add up the Voc values. The current stays the same.
• Parallel (plus to plus): add up the Isc values. The voltage stays the same.

Usable solar is the lower of the panels’ total watts and the port’s maximum watts.

Worked examples

PowMr 100W flexible (on Lazada). PowMr lists Voc 21.6V, Isc 6.11A, Vmp 18V.

• RIVER 3, 1 panel: 21.6V ≤ 28.5V ✓. 6.11A ≤ 8A ✓. 18V ≥ 11V ✓. Passes, with up to 100W usable.
• RIVER 3, 2 in series: 43.2V > 28.5V ✗. Fails.
• RIVER 3, 2 in parallel: 12.22A > 8A ✗. Fails.

PowMr 150W flexible (on Lazada). PowMr lists Voc 21.6V, Isc 9.16A, Vmp 18V.

• RIVER 3: 9.16A > 8A ✗. Fails on current, even though the voltage is fine.
• RIVER 3 Plus, 2 in series: 43.2V ≤ 52.25V ✓. 9.16A ≤ 13A ✓. Passes, but the port caps usable solar at 220W.
• DELTA 3, 2 in series: 43.2V ≤ 57V ✓. 9.16A ≤ 15A ✓. Passes, with 300W usable.
• DELTA 3, 3 in series: 64.8V > 57V ✗. Fails.

BLUETTI PV200 (on Lazada; pick the PV200 variant). BLUETTI PH lists Voc 26.1V, Isc 10.3A, Vmp 20.5V, with a standard MC4 connector.

• RIVER 3: 26.1V ≤ 28.5V ✓, but 10.3A > 8A ✗. Fails.
• RIVER 2 Max, 1 panel: 26.1V ≤ 47.5V ✓. 10.3A ≤ 13A ✓. Passes, with 200W usable.
• RIVER 2 Max, 2 in series: 52.2V > 47.5V ✗. Fails.
• DELTA 3, 2 in series: 52.2V ≤ 57V ✓. 10.3A ≤ 15A ✓. Passes, with 400W usable.
• DELTA 3, 2 in parallel: 20.6A > 15A ✗. Fails.

The same listing also sells the Sora 220 as a variant, which has different figures (Voc 25.9V, Isc 11A), so check which one you receive.

Step 4: Get the right connector

EcoFlow RIVER and DELTA 3 solar inputs are XT60i. For an MC4 panel, use EcoFlow’s Solar to XT60i Charging Cable (EcoFlow PH store) or an MC4-to-XT60i adapter cable on Shopee. Match red to positive. PowMr does not publish the connector type for its flexible panels, so check what is fitted before you order an adapter.

Panels we can’t check

Some panels publish no Voc or Isc (for example the PowMr 100W and 200W rigid listings, the PowMr 200W flexible and the Flowatt panels). Others, like the BLUETTI PV350S, have three different spec sets across official pages. Skip these until you can read a reliable label.

Safety and warranty

This check uses published limits. It is not an EcoFlow approval, so read your station’s warranty terms. Plug-and-play panels on the ground are something you can set up yourself by following the manuals. Anything wired into your house, breaker panel or roof needs a licensed electrician and an LGU electrical permit. For the same maths applied to charge controllers, see matching panels to a charge controller.

What to buy

• MC4-to-XT60i adapter cable on Shopee
• Panels that passed above: PowMr 100W flexible, PowMr 150W flexible, BLUETTI PV200. Check today’s price.
• Stations used in the examples: RIVER 3, RIVER 2 Max, RIVER 3 Plus, DELTA 3.

Bottom line

Brand doesn’t matter. Numbers do. Keep the total Voc at least 5% under the port’s maximum, keep the total Isc at or under its current limit, use a proper MC4-to-XT60i adapter, and a third-party panel can charge your EcoFlow.
