    4kWh Power Kits offer energy for carefree off-grid living and RV trips. Expand this kit to 6kWh by adding another battery. 

    Easy Set Up - The integrated EcoFlow Power Hub has a simple plug-and-play design, allowing you to expand and customize your kit faster than any other power solution on the market.

    Save Space - EcoFlow Power Hub combines two MPPT solar charge controllers, one battery charger with MPPT, one DC-DC step-down converter, and an inverter charger. With fewer modules and thinner wires, this 48V system saves you space and installation hassle.

    Charge Your Way - EcoFlow Power Kits support multiple charging methods. Get plenty of solar power, use your alternator, plug-in shore power, or even use an EcoFlow Smart Generator for emergency charging.

    4 Charging Methods


    You might be on the road, but there are plenty of ways to charge, and fast.

    We’ve designed a new range of rigid and flexible solar panels giving your van a solar input of up to 4800W*. Use your alternator to recharge with 1000W.

    Spending the night on a campsite? Then take advantage of shore power for an extra 3000W. Caught short? Rely on our Smart Generator for emergency backup.



    Setups Made Simple

    Simple Assembly

    We made our modular system plug-and-play so you can quickly customize your van power whenever you want. Simply stack a battery to increase capacity, or plug in a solar panel for faster charging.

    We’ve got experts on-hand to guide you through the installation process or put you in touch with authorized and reputable installers.

     


    Space-Saving Solutions


    To save your valuable space, we shrank down the traditional power kit, integrating components, using thinner wires, and creating a unique stackable battery.

    Conveniently conceal the Power Hub, batteries and other accessories so they’re out of sight, under seats or in a closet.


    48V, a safer, smaller power solution.

    Power Kits offer you a safe, 48V power solution for your off-grid home.

    A 48V system produces the same amount of power, but unlike 12Vs, only a quarter of the electric current passes through thinner wires, producing significantly less heat and power loss.


    Smart Controls. 

    Keep an eye on your energy at home and on the go with a whole host of setting options and real-time data tracking accessible from the app and Power Kit Console.
