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. Learn more about DELTA Max >>

Fast Solar Panel Recharging The DELTA Max can be fully recharged from two EF 400W Solar Panels in 2.5-5 hours, depending on sunlight conditions. An MC4 to XT60 Solar Cable is included.

Smart Solar Energy The EcoFlow 400W solar panel has a conversion efficiency of 22.4%, and when paired with an EcoFlow portable solar generator, can extract the most power throughout the day. The solar generator adjusts its efficiency using the Maximum Power Point Tracking (MPPT) algorithm, to deliver a constant power supply.

Self-supporting The protective case conveniently turns into a stand that adjusts from 40-90° allowing the solar panels to capture the most rays.  Learn more about 400W Solar Panel >>

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.

Expandable Capacity

Dual Charging

Power Multiple Devices

Solar Power

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 65 minutes. 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 to get up to 3600W, AC with solar to get up to 2600W, or the Smart Generator with solar to get up to 2600W.

Power 99% of your home devices.

With EcoFlow’s X-Boost technology, DELTA Max can power heavy-duty devices up to 3400W. 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 MC4 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.

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.

Multiple ways to charge.

Frequently Asked Questions

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, 10A 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-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.

I love it, but it is very heavy, but I will buy other solar panel.

Perfect!

Excellent !!! Bought it literally one day before a 10 day power outage hit our area. Great supplement to when you don’t want to run the generator.

FIrst use review

My new Delta Max 2000 is installed in my outside shed which is within 10 feet of the side garage door. I installed a 4 pole L14-20R receptacle on the outside of the wooden shed that will be used for the Derlta Max AC output. A transfer switch and cable are in the garage. Also added to the shed was a NEMA 5-20 plug for the Delta Max AC input charge line. Next will be 400 watt solar panels on the roof. Today I powered both my washing machine AND the gas dryer doing two loads. The Delta Max worked fine and when the wash was done it had only dropped down to 70%. Amazing, quiet power source. The spare battery just arrived so that's going in right away. The phone app is a nice touch to keep an eye on loading and charge rate.

Great Product for Critical Home Backup

I purchased a few of these as backups for my sump pumps. The Delta has the power output and storage capacity to last for days. Plus the ability to monitor and control them remotely is great for peace of mind when we are away.

2000 Delta Max as UPS.

I have the 2000 Delta Max setup as UPS. When I do a firmware update, the unit shuts down and router shuts down. The firmware update stops. Disconnect router from Delta Max before preforming firmware update.
