EcoFlow DELTA Max + 2 x 400W Rigid Solar Panel
Your home safety net With up to 6kWh capacity, DELTA Max can expand with additional smart batteries
DELTA Max
Home emergency power - DELTA Max expands up to 6kWh with smart extra batteries, keeping your home powered on in any emergency.
Rapid dual charging - Charge up from 0-80% in 65 minutes. Or get up to 3400W speeds by combining AC charging and the EcoFlow Smart Generator.
Power multiple devices - Looking for something to power heavy-duty devices like your fridge and dryer? With X-Boost, DELTA Max handles devices up to 3400W with ease.
400W Rigid Solar Panel
Fast Charging - With a high conversion efficiency rate of up to 23%, the 400W panel charges your LFP batteries faster than similar-sized solar panels.
Weatherproof & Durable - The rigid panel balances design with robust materials allowing the panel to weather any storm while offering the same excellent performance and aesthetics for years.
Off & On-grid Solution - This high-wattage panel works for both on-grid and off-grid solar-powered setups, storing energy for outages, reducing power bills, or powering an off-grid home.
Universally Compatible - The 400W solar panel includes a 300mm charging cable that gives you plenty of space, maximizing solar input. With an all-inclusive solar connector, the 400W rigid panel works with other 3rd party solar systems and power stations.
DELTA Max Smart Extra Battery
More of DELTA Max - Double runtime with this add-on battery that plugs into any DELTA Max portable power station. Add up to two Extra Battery units for a total capacity of 6048Wh.
Convenient recharging - DELTA Max and its Extra Battery charge and discharge in unison. Whether you're recharging DELTA Max from solar panels, AC outlets, a vehicle, or our Smart Generator, the DELTA Max Extra Battery will recharge alongside.
Expandable home backup power
A single DELTA Max unit packs a 2kWh capacity that is expandable up to 6kWh with DELTA Max smart extra batteries. This means when a blackout hits, you can continue to power your important home devices such as your fridge and lights for hours on end.
Convenient and fast dual charging
DELTA Max charges up safely and rapidly from 0-80% in just 1 hour. And it gets even better. If you're looking for an even faster way to charge up DELTA Max, you can combine AC with the Smart Generator, AC with solar, or the Smart Generator with solar.
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 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.
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 the 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 is it?
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 this product?
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.
