  • Ecoflow does it again! Great unit for cutting electrical bills.
Style: DELTA 2 Max+2*220W Solar Panel
Ecoflow does it again with another banger of a system! I took this unit out camping for a little over a week with some of my friends, and with the 2 extra batteries, and 440W Worth of bifacial Ecoflow panels we had power continuously. I only needed to break out the panels around day 4 to charge it back up. Keeping all of our electronics (drones, RC cars, portable fridge cooler, CPAP machines, etc) charged/powered up wasn’t an issue for this unit, and the lowest I ever saw it go was around 30% initially I charged it up a little off of my Honda eu1000 since the clouds were out in the morning, which worked well since ecoflow added a variable wattage AC charging feature! You can limit the wattage it pulls off of AC so you can run smaller (or larger) generators as a backup. That alone makes this unit very versatile. I switched over to solar around 50% charge, and After a full day of sun it was back to full. I Highly recommend this system if you plan on boondocking, or over-landing, as it will power just about anything you will throw at it with 2400w (4800w burst) of output. The system is a little bulky, but it fits well in the corner of a tent. The displays are bright and easily read from a distance, so checking on it outside the tent was easy. Overall this would be a great system for home backup or outdoors adventures! Update! I’ve been using this unit with about 1200w worth of panels outside of my house since march to power my laundry room. I have one of the Samsung bespoke combo washer/dryer units that is a heat pump design, and it has run that thing flawlessly. And with those panels outside, it hasn’t been plugged into the grid for about 7 months now! Using the sun to wash my clothes is so cool! It’s fully topped back off each day, and even with a little cloud cover, it recovers nicely since I over-paneled it. I’ve been so impressed with this unit, that I ended up diving in deep and purchased 2 of their ultra systems (12kWh each), a smart home panel 2 and over 11kW worth of panels in my back yard! We’ve had a couple power outages where I am at, I didn’t notice they happened until I saw all of the other houses in my neighborhood were dark… haha. Even better is my electric bill is all but non-existent. ... show more

  • One year review
Style: DELTA 2 Max Extra Battery
The media could not be loaded. When I first bought this unit I tested it out and it seemed to be working both AC and solar charging with the provided solar panel. Like many of you I bought it as a emergency solar generator. But then I started using it as a daily source of power and purchased also the two backup batteries that go with the unit and a echo-worthy solar panel tracker to provide solar input. Here is what you need to know I have not been able to get this unit to take input on both inputs at the same time and they will not take the 500 watts that it says that it will take as solar input per input. I started in 2025 trying to get this problem addressed I have followed different instructions such as updating the firmware resetting the unit I've even gone to the expense of paralleling the panels input into the Delta 2 max. To increase amperage input and still remain below the 60 volt limit per input. We have not been able to get the Delta 2 max to take more than 15 amps at 23.5 volts. It should be capable of taking in 21 amps at 23.5 volts. Although this seems to be an American company on paper there tech support apparently is out of India, and I have had a hard time understanding them and they do not have tech support in the USA. I really wanted this system to work and I will come back and give more stars if they are able to either fix my problem or replace this defective unit. ... show more

  • Easy enough to set up but with one small catch
Style: DELTA 3 Max+2*220W Solar Panel
Worried about a long power outage ruining the contents of your refrigerator? This power station with 2 huge solar panels will put that to rest. They say it's portable but hefting in at close to 50 lbs., I won't be taking this out on the road. That's not a complaint but praise for a small unit packed with enough batteries to keep my food cold as long as the sun shines once in awhile. The only ding against this pairing is the adapter cable to attach the solar panels to the power station. It is NOT included and must be ordered separately from EcoFlow. ... show more

  • I like it
Style: DELTA 3 Max+500W AC
This unit came quickly and has really nice packaging. Charges quickly and seems to output plenty of power. Time will tell if it holds up but it sure seems like a very nice unit.
