How to Connect a Solar Panel to an EcoFlow (Step-by-Step)
Connecting a solar panel to an EcoFlow power station is straightforward once you understand the voltage and connector requirements. This step-by-step guide walks you through the process safely.
Quick Answer
To connect a solar panel to an EcoFlow: (1) Check the panel's Voc is within your EcoFlow's voltage range, (2) Ensure you have the correct adapter (MC4 to XT60 for most EcoFlow models), (3) Connect the panel to the adapter, (4) Connect the adapter to the EcoFlow's solar input port. Never exceed the voltage limit — it can damage the station.

Step 1: Verify voltage compatibility
Before connecting anything, find your panel's open-circuit voltage (Voc) on its spec label or documentation. Then check your EcoFlow model's solar input voltage range (RIVER Pro: 10-25V, DELTA 2: 11-60V, DELTA Pro: 11-150V). If the panel's Voc exceeds your EcoFlow's maximum, do NOT connect it — it can permanently damage the station. This is the most important safety check. Manufacturer specifications may change — verify for your specific model.
Step 2: Get the right adapter
EcoFlow stations use an XT60 connector for solar input. Most solar panels use MC4 connectors. You need an MC4-to-XT60 adapter (included with EcoFlow-branded panels and many panels sold for EcoFlow). If your panel uses a different connector (Anderson, DC barrel), you need the matching adapter. EcoFlow sells official adapters; third-party adapters also work. Always use a quality adapter — a poor connection wastes power as heat and can melt.
Step 3: Connect the panel
With the EcoFlow powered off, connect the panel's MC4 output to the MC4-to-XT60 adapter. Then connect the XT60 end to the EcoFlow's solar input port (labeled with a solar panel icon, separate from the AC charging port). Ensure connections are firm and fully seated. Partially connected XT60 connectors cause resistance and heat. Once connected, power on the EcoFlow — it should detect solar input and display charging wattage on the screen.
Step 4: Position the panel for maximum output
Position the panel facing south (in the Northern Hemisphere) tilted at an angle roughly equal to your latitude. Adjust the angle seasonally — steeper in winter, flatter in summer. Avoid all shading — even partial shade on one cell can reduce panel output by 50-80%. For portable panels, use the kickstand to set the angle and reposition every 2-3 hours to track the sun, increasing daily yield by 25-40%.
Frequently Asked Questions
Can I connect any solar panel to my EcoFlow?
Not any panel — the panel's open-circuit voltage (Voc) must be within your EcoFlow's solar input voltage range, and you need the correct connector (usually MC4 to XT60). Check your EcoFlow model's specs and the panel's Voc before connecting. Exceeding the voltage limit can damage the station.
What adapter do I need to connect a solar panel to an EcoFlow?
Most EcoFlow stations use an XT60 solar input, and most solar panels use MC4 connectors. You need an MC4-to-XT60 adapter, which is included with EcoFlow-branded panels and available separately. If your panel uses a different connector (Anderson, DC barrel), match the adapter to your panel and EcoFlow model.
Can I connect two solar panels to one EcoFlow?
Yes, if the combined voltage (series) or current (parallel) stays within the station's limits. For RIVER models with low voltage limits, parallel wiring keeps voltage safe. For DELTA models with higher voltage limits, series wiring may improve efficiency. Always verify combined specs against your station's limits before connecting.
