Backup your home during power outages with DELTA Max. With an expandable capacity that reaches up to 6kWh, dual charging, and the ability to power your home devices, you can stay powered on in any situation.
Power multiple devices
800W max Solar Input
Power 99% of your home devices.
With EcoFlow’s X-Boost technology, DELTA Max can power heavy-duty devices up to 3000W. That means during a power outage or blackout, you can continue to power your fridge, dryer, and more. That’s the industry gold standard for a portable power station of this size and capacity.
Harness the power of the sun.
DELTA Max connects with up to 2x 220W EcoFlow solar panels to deliver fast solar charging speeds. With a voltage range from 11-100V and the solar connector, you can also connect other solar panels to your DELTA Max. Even during cold or cloudy days, our smart maximum power point tracking (MPPT) algorithm automatically detects voltage and current in real time to give you optimum solar generation throughout the day.
Control, monitor, and manage your energy use.
Control and monitor your DELTA Max with the EcoFlow app. Dive into the settings to customize your power use or control DELTA Max remotely.

Frequently Asked Questions
Depends on the total voltage and watts of solar panels you choose. As long as the solar panels use solar connector and its voltage and current are under 11-100V, 13A max range.
When charging DELTA Max and its extra battery together, you can reach 3600W max charging speeds by combining any two methods of AC, solar and Smart Generator. For DELTA Max single unit, you can recharge it at standard wall outlets (1800W max), or combine AC and solar charging to reach max 2000W charging speeds.
When your portable power station is plugged into the wall, any electronics plugged into it are powered from the grid and not its battery. When power from the grid stops, as in a blackout, the power station automatically switches to battery power within 30ms.
DELTA Max is not water-resistant, so it should be kept away from liquids. Or if you’re looking for water-resistance solution, you can purchase the DELTA Max case to water-resistance protection.
Increase the efficiency of your solar panel by facing it directly at the sun without any obstructions. Remember to be careful when handling your solar panel because damaged cells provide less power.
Yes, if the only thing between it and the sun is transparent, but it won’t charge as well compared to being outside. You can compare the difference by looking at the input section of your power station’s LCD screen.
