EcoFlow Solar Panel Compatibility: RIVER Pro, RIVER 2 Pro & DELTA 2
Looking for the best solar panel for an EcoFlow RIVER Pro, RIVER 2 Pro, RIVER 2 Max, DELTA 2, or DELTA Pro? Start with the station's PV input limits, not the logo on the panel. This guide compares verified EcoFlow voltage, current, and wattage limits and shows how to check a third-party panel before connecting it.

Quick answer: which solar panel fits my EcoFlow?
Match the panel or array to the exact EcoFlow model's PV input voltage, current, and wattage limits. The original RIVER Pro is not the same as the RIVER 2 Pro: EcoFlow lists the original RIVER Pro at 10–25V, 12A, 200W max solar input, while the RIVER 2 Pro is listed at 11–50V, 13A, 220W max. DELTA 2 is listed at 11–60V, 15A, 500W max. Check panel Voc, Isc/Imp, wiring, connector and polarity before connecting.

EcoFlow 400W Portable Solar Panel
by EcoFlow
Listed as a 400W portable monocrystalline panel. Verify the current unfolded size, weight, weather rating, connector arrangement, and power-station input compatibility before purchase.
Who this is for
- 400W-class portable nameplate rating
- Portable rather than permanent-mount format
- Relevant to large power-station charging setups
Avoid if
You need a lightweight backpacking panel or your power station cannot accept the proposed input
Verified EcoFlow Solar Input Specifications
These limits were checked against current EcoFlow product pages or manuals. Voltage is the first hard safety limit, but current matters too. A physically compatible adapter does not make an electrically incompatible array safe. Recheck the manual for your exact model and revision before wiring panels.
| EcoFlow Model | Voltage Range | Current Limit | Max Solar Input | Connector |
|---|---|---|---|---|
| EcoFlow RIVER Pro | 10–25V | 12A max | 200W max | Solar-to-XT60/XT60i cable |
| EcoFlow RIVER 2 | 11–30V | 8A max | 110W max | Solar-to-XT60/XT60i cable |
| EcoFlow RIVER 2 Max | 11–50V | 13A max | 220W max | Solar-to-XT60/XT60i cable |
| EcoFlow RIVER 2 Pro | 11–50V | 13A max | 220W max | Solar-to-XT60/XT60i cable |
| EcoFlow DELTA 2 | 11–60V | 15A max | 500W max | Solar-to-XT60/XT60i cable |
| EcoFlow DELTA 2 Max | 11–60V | 15A per solar input | 500W per port / 1,000W dual | Solar-to-XT60/XT60i cable |
| EcoFlow DELTA Pro | 11–150V | 15A max | 1,600W max | Solar-to-XT60/XT60i cable |
Manufacturer specifications may change. Always verify voltage range and connector type for your specific EcoFlow model before connecting a solar panel.
EcoFlow RIVER Pro vs RIVER 2 Pro: do not mix up the limits
Searchers often use “RIVER Pro” and “RIVER 2 Pro” interchangeably, but EcoFlow gives them different PV input ranges. The original RIVER Pro manual lists 10–25V, 12A and 200W max solar input. The newer RIVER 2 Pro product specification lists 11–50V, 13A and 220W max. That wider voltage window can change which panels or series/parallel arrangements are acceptable.
Before buying a third-party panel, read the panel label for Voc, Vmp, Isc and Imp. If you are combining panels, calculate the resulting array voltage and current for the chosen wiring method. Do not size an array from wattage alone, and do not rely on a product title that merely says “EcoFlow compatible.”
Connectors & Adapters
Many third-party solar panels use MC4-style connectors.EcoFlow uses XT60 or XT60i solar-input cabling on many RIVER and DELTA models. Confirm the exact cable specified for your station. An MC4-to-XT60/XT60i adapter changes the physical connection only; it does not correct excessive voltage, current, reversed polarity, or an unsafe series/parallel configuration.
Critical: Never exceed your EcoFlow's maximum solar input voltage. Connecting a panel array with a combined Voc above the station's limit can permanently damage the unit. Check your panel's Voc on its spec label and compare it to the table above before connecting.
Series vs parallel for EcoFlow. With matched panels, series wiring adds voltage while parallel wiring adds current. Neither method is automatically correct for a RIVER or DELTA model. Calculate the array's combined Voc and current and compare both with the exact station's limits. Cold weather can raise Voc, so series strings deserve additional margin based on the panel's temperature coefficient and manufacturer guidance.

Frequently Asked Questions
Can I use any solar panel with my EcoFlow?
No. The panel or array must stay inside the exact EcoFlow model's PV voltage, current and power limits, and the connector and polarity must match. A third-party panel can be compatible without being EcoFlow-branded, but compatibility has to be checked from the electrical specifications.
What solar panel fits the original EcoFlow RIVER Pro?
EcoFlow's RIVER Pro manual lists 10–25V, 12A and 200W max solar input. Choose a panel or parallel array whose electrical specifications remain inside those limits, and use the cable specified for the RIVER Pro. Do not confuse this model with RIVER 2 Pro.
What solar panel fits EcoFlow RIVER 2 Pro?
EcoFlow lists RIVER 2 Pro solar input at 11–50V, 13A and 220W max. Compare a candidate panel's Voc, Vmp, Isc and Imp with those limits before purchase.
How much solar input does EcoFlow DELTA 2 accept?
EcoFlow lists DELTA 2 solar charging at 11–60V, 15A and 500W max. If you combine panels, calculate both the resulting voltage and current rather than adding wattage alone.
Can I connect two solar panels to one EcoFlow station?
Sometimes. Series wiring raises voltage and parallel wiring raises current. The combined array must remain within the exact station's voltage, current and power limits, including cold-weather Voc considerations.
