The media could not be loaded. I've been using the new EcoFlow DELTA 3 Max Plus for both our small farm and our RV, and it's already become an essential part of daily life. The 3000W output is strong enough to handle appliances and tools without me constantly swapping cords, and the UPS feature switches over so quickly that I don't worry about sensitive electronics. I currently have it paired with two EcoFlow 220W bifacial solar panels, and I consistently pull in around 380-390W here in Erie, Colorado, even when conditions aren't perfect. The charging flexibility is impressive whether wall, solar, or generator and the LFP battery tech gives me confidence it'll last for years. It's not exactly lightweight, but for the capacity and performance, think the size and weight are reasonable. If you're looking for something that can power an RV, back up your home during outages, or just keep life running smoothly on a property, the DELTA 3 Max Plus is about as close to "peace of mind in a box" as you can get. Highly recommended it! Ecoflow solar generators have saved us a number of times in different situations or power outages. Read more
I purchased this combo for the larger inverter and more solar input to power my camper and home office. This Delta unit is awesome. Its sleek looking and well thought out. The ability to harness 1000w of solar input via two 500w solar input ports is really cool (if one needed that much input). I set it up early in the morning so the solar conditions weren't great but I still got about 250w coming in. I can imagine having 2 of these panels in parallel for each port. That would safely over panel each solar charger while maximizing the input even during poor solar conditions. An obvious reality is the panel is quite large and heavy... probably the largest it could be and still be considered "portable". It took a little time to get it set up by myself. I suggest having a second person and/or patience trying to get it set up for maximum efficiency. I know there are already in-depth reviews for the D3M+ regarding capacity, efficiency, power, etc. I suggest reviewing those for complete analysis... but I can say so far I am super happy and excited about this Delta unit and solar panel. It will run my home office as well as my camper when I am away from home. I particularly like the new addition of the 12v anderson power pole they have finally included. That opens the door for much higher dc outputs. I have several Ecoflow products and believe these are the best units out there. Customer Service was wonderful resolving a couple previous warranty issues. No hassle getting replacement units / fixes rather quickly. I highly recommend. I would give more than 5 stars if it were possible. Great job again Ecoflow! Read more
Great little UPS. Far superior to the other non-LFP products. Got really tired of having to replace 250.00 worth of sealed lead acid batteries every two years. The LFP batteries in this unit should last 10 years.? We'll see. Read more
The Delta 3 Max+ is a great solar generator. This is the largest Ecoflow device I own. I took it camping about two weeks ago. It kept our campsite powered all weekend! The pictures show it next to the Delta 3 plus for comparison. Read more
I have had my unit for over a week and now ready to give my review for the Delta 3 Max Plus. I love love the fact I can put 1kw of solar into it. The biggest problems with a lot of competitors units is you cannot get enough solar power into the unit to make it a true backup power system for a substantial period of time. I have this unit in my garage running two lamps, a small freezer, a few battery chargers and my exercise bike with no issues. Read more
Perfectly sized power station for backing up essential appliances when needed. Read more
The media could not be loaded. 1/7/26 Update: Amazon stepped up and took care of me, kudos to Amazon. Just beware that you may have issues using this to power your microwave, which is what I purchased it for. Original review: Ugh, I found a post on the Ecoflow Facebook group describing an issue where the Delta 3 Max Plus wouldn’t power a microwave. Unfortunately, I found it after I placed my order and mine has the issue. I suspect it’s a problem with the new 3k inverter. Anyway, I emailed Ecoflow with the video, we’ll see how they respond.
