EcoFlow Solar Parallel Connection Cable for RIVER and DELTA Series
EcoFlow Solar Parallel Connection Cable for RIVER and DELTA Series
The EcoFlow Solar Parallel Connection Cable allows compatible solar panels to be connected in parallel when charging selected EcoFlow RIVER and DELTA Series portable power stations.
Parallel connection combines the current output of compatible solar panels while maintaining a similar voltage, helping increase the available solar charging power when the connected EcoFlow power station supports the combined input.
The cable can be used to connect up to two compatible solar panels for selected RIVER Series power stations or up to four compatible solar panels for selected DELTA Series power stations, subject to the voltage, current and wattage limits of the connected power station.

Product Overview
The EcoFlow Solar Parallel Connection Cable is designed to connect multiple compatible solar panels in parallel before connecting them to a supported EcoFlow portable power station.
A parallel solar connection combines the current produced by the connected panels while the voltage remains close to the voltage of a single panel.
This can increase the total solar charging power available to the portable power station, provided the combined current, voltage and wattage remain within the power station’s supported solar-input limits.
EcoFlow recommends the cable for connecting:
• Up to two compatible solar panels when charging selected RIVER Series power stations
• Up to four compatible solar panels when charging selected DELTA Series power stations
The actual number and type of panels that can be connected depend on the electrical specifications of the solar panels and the maximum solar-input limits of the connected power station.

How Parallel Connection Works
When compatible solar panels are connected in parallel:
• The panel voltage remains close to the voltage of one panel
• The available current from the panels is combined
• The combined wattage may increase
• The connected power station determines how much solar power it can accept
For example, two matching panels connected in parallel may provide approximately the voltage of one panel while producing a higher combined current.
Actual charging performance depends on the connected panels, sunlight conditions and the solar-input limits of the portable power station.
Compatibility
The cable is intended for use with selected:
• EcoFlow RIVER Series portable power stations
• EcoFlow DELTA Series portable power stations
• EcoFlow portable solar panels fitted with compatible solar connectors
• Supported third-party solar panels with matching connectors and electrical ratings
Compatibility must be confirmed using the specifications of both the solar panels and the connected power station.
Important Compatibility Note
Before connecting multiple solar panels, confirm:
• The open-circuit voltage of each panel
• The operating voltage of each panel
• The short-circuit current of each panel
• The operating current of each panel
• The total combined current
• The total combined wattage
• The solar-input voltage range of the power station
• The maximum supported solar-input current
• The maximum supported solar-input wattage
• The connector type used by the panels
A matching connector does not automatically guarantee electrical compatibility.
Do not connect panels if the combined electrical output exceeds the supported limits of the connected EcoFlow portable power station.
Panel Matching Note
For the most stable and predictable performance, use matching solar panels with the same:
• Rated wattage
• Operating voltage
• Open-circuit voltage
• Operating current
• Connector type
• Cell technology
Connecting panels with different electrical ratings may reduce charging performance or cause the output to be limited by the lower-performing panel.
RIVER Series Connection Note
EcoFlow states that the parallel connection cable can be used to connect up to two compatible solar panels for selected RIVER Series power stations.
This does not mean that every RIVER model can accept the full combined output of any two panels.
Always confirm the specific RIVER model’s:
• Maximum solar-input wattage
• Supported solar-input voltage range
• Maximum solar-input current
• Required charging cable or connector
DELTA Series Connection Note
EcoFlow states that the parallel connection cable can be used to connect up to four compatible solar panels for selected DELTA Series power stations.
The supported configuration depends on the specific DELTA model and the electrical output of the connected panels.
Some DELTA models may accept fewer panels when higher-output solar panels are used.
Do not exceed the connected DELTA power station’s voltage, current or wattage limits.
Required Additional Cable
The parallel connection cable joins the compatible solar panels together.
A compatible Solar-to-XT60 or Solar-to-XT60i charging cable may also be required to connect the combined solar-panel output to the EcoFlow portable power station.
The Solar-to-XT60 or XT60i charging cable is sold separately unless included with the solar panel or power station.
Check the connector supplied with your EcoFlow power station before ordering.
Installation Instructions
- Place the compatible solar panels in a suitable position with direct sunlight.
- Confirm that the panels have matching electrical specifications.
- Connect the positive solar connectors to the matching positive branches on the parallel cable.
- Connect the negative solar connectors to the matching negative branches on the parallel cable.
- Connect the parallel cable output to the required EcoFlow solar charging cable.
- Connect the charging cable to the solar-input port on the EcoFlow power station.
- Confirm that the power station detects solar input.
- Monitor charging performance and ensure the cables and connectors do not become excessively hot.
Always disconnect the solar input before changing the panel configuration.
Solar Performance Note
Connecting solar panels in parallel does not guarantee that the power station will receive the full combined rated wattage.
Actual solar charging output depends on:
• Sunlight intensity
• Panel angle and orientation
• Cloud cover
• Ambient temperature
• Panel temperature
• Partial shading
• Dirt or dust on the solar panels
• Cable length and electrical losses
• Solar-panel condition
• Power station battery level
• Power station solar-input limits
For improved performance, position all connected solar panels in direct sunlight at a similar angle.
Safety Information
• Confirm electrical compatibility before connecting the panels
• Do not connect damaged cables or connectors
• Keep connectors clean and dry
• Do not connect or disconnect wet plugs
• Ensure positive and negative connectors are connected correctly
• Do not exceed the power station’s input limits
• Do not sharply bend, crush or pinch the cable
• Keep cables away from sharp edges and high-temperature surfaces
• Disconnect the panels before changing the connection layout
• Do not modify or cut the cable
• Do not use unsupported adapters or damaged extension cables
