Harness The Power Of The Sun
DELTA Max connects with up to 2x 400W EcoFlow solar panels to deliver 800W Max 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.
Plug & Play Home Backup Power
Power your essential appliances with 2000W huge AC output by directly connecting the DELTA Max with your home's power inlet box* with a generator cord for partial home backup. With a plug-and-play design, it's easier than ever to prepare for blackouts. *including transfer switch or GenerLink which has a male L14-30 twist-lock connection that can accept a L14-30 extension cord.
Emergency Backup Power
Disasters can occur at any time of the year, sometimes lasting longer than we ever expected. When extended blackouts hit, the EcoFlow Smart Generator serves as an emergency option that integrates with DELTA Max. It auto-starts when your DELTA Max hits a low level of charge, recharges your DELTA Max, and stops the engine all by itself once your DELTA Max hits a full charge. This gives you a reliable emergency backup option that relies on minimum use of a generator.

Frequently Asked Questions
How many solar panels can I use at the same time with DELTA Max?
It depends on the total voltage and watts of solar panels you choose. As long as the solar panels use MC4 connector and its voltage and current are under 11-100V, 13A max range.
What’s the max input for DELTA Max?
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.
How does the Emergency Power Supply (EPS) work? And how fast isit?
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.
What’s the water-resistance rating for DELTA Max?
DELTA Max is not water-resistance, 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.
