Harness the power of the sun.

The DELTA Max unit connects with up to 2 x 400W EcoFlow solar panels to provide solar charging speeds up to a maximum of 800W. With a voltage range of 11 to 100V and MC4 connector, it is also You can connect other solar panels to your DELTA Max unit. Even on cold or cloudy days, our intelligent MPPT (Maximum Power Point Tracking) algorithm automatically detects real-time voltage and current to ensure optimum solar energy delivery throughout the day.

Backup energy in case of emergency.

Unforeseen emergency situations can occur at any time of the year and sometimes last longer than we expected. In the event of an extended power outage, the EcoFlow Smart Generator functions as a backup option complementing the DELTA Max unit. It starts automatically when DELTA Max reaches a low charge level, recharges DELTA Max and automatically stops when DELTA Max reaches full charge . It offers a reliable backup option in the event of a disaster that relies on minimal use of a generator.
