The EcoFlow DELTA MAX is one of the most anticipated solar powered generators ever built for off-grid, RV, Van Life, and home backup emergency situations. It offers expandable battery capacities starting at 2kWh all the way up to 6kWh. The Delta MAX is also the fastest charging solar generator on the market, fully re-charging in under 2 hours, and comes with 3600W dual charging.
Not only that, the DELTA Max features 3400W X-Boost, capable of powering basically anything you could throw at it. The Delta MAX comes with 35% more storage & 100% more peak power... so you get more power for longer. Plus, this kit comes with all of the cables and accessories needed to get up and running with off-grid solar power!
The combination of the enormous 2,016Wh battery, powerful 2,400W inverter, and 15 output ports means that the DELTA Max can offer an outstanding amount of backup power to a wide variety of electronic devices and appliances.
To give you an idea of its incredible capabilities, consider the fact that a fully charged DELTA Max could be used to supply power in the following ways:
| Appliance | Run Time |
|---|---|
| CPAP Machine (40W) | 40 hours |
| Refrigerator | 25+ hours |
| Slow Cooker | 20 hours |
| Basic Power Tools (80W) | 20 hours |
| 32” LED Television | 22 hours |
| Laptop Computer | 20 Recharges |
| Standard Smartphone (iPhone 12) | 200+ Recharges |
The DELTA Max is so powerful that it can even be used to run heavy-duty power tools, including the most demanding devices, like arc welding machines. It can even be used as an emergency source of power for electric vehicles.
Run up to 15 Devices Simultaneously:
Like its predecessor, the DELTA Max offers incredible versatility. No matter what you need to plug in, the DELTA Max’s 15 output ports have you covered:
| # of Plug(s) | Type of Plug(s) |
|---|---|
| 6 | 120V (50/60Hz) AC wall ports |
| 2 | USB-A 12W ports |
| 2 | USB-A 18W ports |
| 2 | USB-C 100W Fast Charging ports |
| 1 | 126W DC Car-Style port |
| 2 | DC5521 3A ports |
While the upgraded battery, power inverter, and charge controller are all incredibly important, the DELTA Max delivers plenty of other exciting features that were not seen in any of EcoFlow’s previous solar generator models:
Wi-Fi Connectivity: The Delta Max is Wi-Fi enabled, which means it is compatible with EcoFlow’s user-friendly mobile app. You can monitor everything from charge output and input information, to the brightness of the LCD screen from your smartphone, tablet, or computer.
This also means that it is compatible with their new Smart Generator, which can quickly and automatically charge your solar generator using gasoline. This is handy when your battery is nearly drained and solar charging is not an option.
X-Boost Charging: The DELTA Max features EcoFlow’s new X-Boost charging, which can deliver 3,400W of power to ensure that your electronic devices are charged as quickly as possible.
Emergency Power Supply Mode (EPS Mode): This new feature automatically turns the DELTA Max on when your main power source fails. It is an incredibly useful feature for emergency preparedness and makes sure you never have to be inconvenienced by sudden power outages.
Expandability: For those with greater storage requirements, you now have the option to connect two external 2,016Wh smart battery packs, which would increase the battery capacity to an incredible total of 6,026Wh!
PLUS..
[Huge Expandable Capacity] - Expandable 2016Wh capacity battery power station. Link two extra batteries to get a massive 6048Wh.
[Multiple Charging Methods] - More than a solar generator. Charge with AC, solar, car or the EcoFlow Smart Generator. Charge to full in 1.8hrs via wall outlets. Use Dual Charging to combine AC with the Smart Generator for industry-leading speeds. Pair solar + AC, or Solar + the Smart Generator for outdoor use.
[Power Pretty Much Anything] - 2400W output to power up to 15 devices at once. Power 3400W appliances with X-Boost on. Ideal power generator for backup power.
[Quality & Reliability] - A portable power station with BMS protection. Monitor voltage, current, short circuit and temp in real-time. Outdoor generator with a rugged build for travel & camping.
Whether you enjoy spending time living off-grid, or you just want to make sure you are prepared for emergency situations and extended power outages, the EcoFlow DELTA Max Quad Kit is the ideal solution. It offers all the benefits of a complete solar power system, but in a highly portable package.
The EcoFlow DELTA Max was designed to be an upgraded and expanded successor to the incredibly popular EcoFlow DELTA 1800. Since it was announced in August of 2021, the DELTA Max has quickly become one of the most exciting products in the entire solar industry.
Despite its compact and lightweight design, the DELTA Max features an enormous built-in 2,016Wh deep-cycle solar battery, which is a massive upgrade over the DELTA 1800’s 1,260Wh battery. As if the increased storage capacity wasn’t enough, EcoFlow also made the DELTA Max expandable, meaning you can increase the battery capacity to a staggering 6,026Wh by adding two compact and affordable external battery packs!
Since the DELTA Max was designed to be a reliable source of emergency power, it is no surprise that the built-in deep-cycle battery is made to last. With a shelf life of over 12 months, users can depend on the DELTA Max to hold at least 80% of its charge for a full year, which means it can be relied upon when you need it the most!
The internal battery is also rated for over 800 cycles, meaning it has a much longer lifespan than the industry standard.
With an exceptionally powerful and efficient inverter that can handle a continuous output of 2,400W and surges of up to 5,000W, the DELTA Max can supply power to even the most demanding electronic devices and appliances.
Using the new X-Boost feature, you can even power appliances that require 3,400W of continuous power!
The DELTA Max offers some of the fasting charging of any solar generator on the market. Thanks to an 800W input charge rating, the massive internal battery can be charged in as little as 1.8 hours! For perspective, generators with a similar battery capacity can take as long as 8 hours to fully charge.
You also have multiple charging options, meaning it can be charged with solar panels, through a traditional AC wall outlet, through a 12V or 24V DC car outlet, or by using a combination of solar and AC power!
The Quad Kit packages the DELTA Max with 4 x 200W 12V monocrystalline solar panels, as well as all of the connectors and cables required to wire everything together. In other words, you get everything you need to generate reliable off-grid power from anywhere the sun is shining.
Back up your home during power outages with DELTA Max portable power generator. 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.
