    Product description

    The possibility of increasing the capacity

    One DELTA Max station has a capacity of 2 kWh, which can be expanded up to 6 kWh using DELTA Max Smart batteries. So if there is a power outage, for example, you can be sure that your appliances, such as your refrigerator or lighting, will still be able to work.

    X-Stream and MultiCharging

    Thanks to X-Stream technology, you can charge the DELTA Max device from 0% to 80% in just 65 minutes. However, if you’re calling for even faster speeds, our brand new MultiCharging dual charging technology combines the ability to charge from an outlet and at the same time from solar panels with a total input of up to 2600W.

    X-Boost technology

    With EcoFlow X-Boost technology, DELTA Max can power more demanding devices with an input of up to 3400 W. This means that during a power outage, a refrigerator, dryer or other appliances can continue to work without problems. Appliances without 230 V voltage requirements (hair dryers, kettles, etc.) with lower power can be connected. However, the X-Boost technology is completely safe for the device, as it maintains a constant sinusoid.

    Powerful solar charging

    Together with the DELTA Max station, you can use EcoFlow solar panels with a total output of up to 800 W. It is therefore possible to connect, for example, 2 × 400 W EcoFlow solar panels. The MC4 connector also allows you to connect other solar panels with a voltage range from 11 V to 100 V, which are commonly available in the market. Even on cold or cloudy days, the Intelligent Maximum Power Tracking (MPPT) algorithm automatically detects real-time voltage and current to ensure optimal solar charging throughout the day.

    Back-up energy for the home

    Power outages can really happen at any time and sometimes last longer than we could ever imagine. In the event of a longer power outage, the EcoFlow Smart Generator together with DELTA Max will reliably serve as backup sources of electrical energy. The generator automatically starts when the DELTA Max reaches a low charge level. Once fully charged, the motor will stop by itself. This gives you an emergency power backup that depends only on minimal generator usage.

    EcoFlow mobile application

    Remotely control and monitor your DELTA Max with the EcoFlow mobile app. In the settings, you can customize the station’s functions according to your needs.

    Recharge options

    When you are at home, simply plug the DELTA Max station into a mains socket or connect the solar panels. If you’re on the go, charge DELTA Max by driving in your car or using solar panels. In extreme situations, such as a power outage, connect DELTA Max to a Smart generator to ensure you are completely energy self-sufficient.
