    The EcoFlow EFMC4-XT60CBL3.5M is a 3.5 m cable with MC4 connectors on one end and an XT60 plug on the other. It links any solar panel with a standard MC4 output to an EcoFlow portable power station (DELTA, RIVER series), so the station can be charged directly from the sun without a grid connection.

  • Product description

    Solar panel cable | MC4 – XT60 | 3.5 m | for connecting EcoFlow DELTA / RIVER to solar panels | EFMC4-XT60CBL3.5M

    The EcoFlow EFMC4-XT60CBL3.5M is a 3.5 m cable with MC4 connectors on one end and an XT60 plug on the other. It links any solar panel with a standard MC4 output to an EcoFlow portable power station (DELTA, RIVER series), so the station can be charged directly from the sun without a grid connection.

    Key idea:
    EcoFlow power stations have an XT60 solar input, while most solar panels on the market have MC4 connectors. This cable is the missing link: it lets you use not only EcoFlow's own panels but any standard panel – from a balcony solar unit to rooftop modules.
    Length
    3.5 m
    Connectors
    MC4 (2 pcs) → XT60
    Compatibility
    EcoFlow DELTA / RIVER series
    Current
    up to 15 A

    How it works

    The solar panel (or a string of panels connected in series) is connected to the cable via MC4 connectors: positive to positive, negative to negative – the MC4 design prevents reversing the polarity. The XT60 plug is inserted into the power station's solar charging port.

    The station's MPPT controller detects the panel voltage and starts charging. The cable itself contains no electronics – it simply carries the DC current, so all parameters (maximum voltage and current) are limited by the power station's specification, not by the cable.

    What makes this cable worthwhile?
    It opens up the ability to charge an EcoFlow power station from any standard solar panel, and its 3.5 m length lets you place the panel in the sun while keeping the station in the shade or inside a tent.

    Key features

    • Standard MC4 compatibility – fits any panel with MC4 connectors, no need for EcoFlow's own panels.
    • XT60 plug – connects straight into the EcoFlow solar input, no adapters needed.
    • 3.5 m length – panel in the sun, station in the shade or in the car.
    • Reverse-polarity protection – MC4 and XT60 both have keyed polarity.
    • Built for outdoor use – connectors are sealed, and the cable is weather-resistant.

    Where is it used?

    • Camping, tents, campervans with an EcoFlow power station
    • Homesteads and garden cabins with no grid connection
    • Balcony solar setups charging a power station
    • Construction sites and temporary work locations with portable power
    • Backup charging when the power goes out at home
    • Fishing, hunting, photography and drone-operator expeditions
    • Outdoor events, market stalls

    Use by need

    For the domestic user.
    You have a RIVER or DELTA and want to charge it from a cheaper, standard panel – this cable solves that without adapters.
    For businesses.
    For mobile crews and field sites – one cable per station, so any panel on hand can be used.
    For electricians.
    Suitable for connecting panels wired in series, as long as the combined open-circuit voltage stays within the station's input limit – check Voc, not just Vmp.

    Practical example

    If you have a 400 W roof panel with an MC4 connector and a DELTA 2 station at your homestead, connect the panel directly with the cable, and the station charges during the day so it can power a fridge and lighting in the evening.

    Pros

    • Versatile – any MC4 panel becomes an EcoFlow charger.
    • Genuine EcoFlow accessory – guaranteed compatibility with the XT60 input.
    • Convenient length – 3.5 m is enough for most outdoor scenarios.
    • No extra adapters – fewer contacts, fewer losses.
    • Polarity protection – you won't reverse plus and minus.

    Cons / limitations

    • XT60 input only – the DELTA Pro and newer stations with a different input require an adapter.
    • No overvoltage protection – the user must check the voltage limit.
    • 3.5 m may be too short for roof-mounted panels – an MC4 extension cable will be needed.
    • Order item – lead time 2–3 business days.

    Safety and installation notes

    • Before connecting, check the panel's (or string's) Voc – it must not exceed the station's maximum solar input voltage.
    • Push MC4 connectors together fully, until they click; disconnect only with a dedicated MC4 tool.
    • Do not connect or disconnect the XT60 plug under load in sunlight – cover the panel or disconnect the MC4 connectors first.
    • Keep the cable clear of sharp edges and vehicle traffic.

    Quick selection guide

    Length
    3.5 m
    Connectors
    MC4 (2 pcs) → XT60
    Compatibility
    EcoFlow DELTA / RIVER series
    Current
    up to 15 A
    Suitable when you need:
    • to connect a standard MC4 panel to an EcoFlow power station;
    • a 3.5 m distance between the panel and the station;
    • a genuine, compatible accessory.
    Check before use:
    • whether your station has an XT60 solar input;
    • whether the panel's Voc and Isc stay within the station's limits;
    • whether the panel's connectors are MC4 (not MC3 or another type).
    Important reminder:
    The cable has no controller of its own – charging is regulated by the station's MPPT. Do not exceed the station's input voltage, as the warranty does not cover damage of that kind.

    FAQ

    Does it work with non-EcoFlow panels?
    Yes, with any panel that has MC4 connectors.
    Can two panels be connected together?
    Yes, as long as the combined string voltage and current stay within the station's limits.
    Does it work with the DELTA Pro?
    The DELTA Pro has a different input – an adapter is required.
    Can it be extended?
    Yes, with standard MC4 extension cables on the panel side.
    Is it rain-resistant?
    The MC4 connectors are sealed; keep the XT60 end protected from direct rain.
