I am so happy I bought this system. We had a power outage shortly after my generator arrived. I was able to hook it up and run appliances, internet, etc.. My husband went off the deep end when this arrived. I just said, my bad. I guess I screwed up. Then when he was at work and power was out at home. What could he say?

One of the best purchases I've ever made! We have an unreasonable amount of power outages in my community and the Ecoflow Delta pro has been a life saver. I recommend every home should have one for emergency purposes, they also come in handy while camping. The one downside is this unit is heavy, but the wheels and telescoping handle help you alot in managing to move it around.

We have a number of EcoFlow DELTA Pros and DELTA Pro Extra Batteries. At home, power goes out frequently, and we use the DELTA Pros as backups for critical loads in our home and garage. At home, we especially appreciate the ability to run 240V loads in our garage using two DELTA Pros and the Double Voltage Hub. In the RV, we have eliminated propane – which is wonderful from a ease of maintenance and safety perspective – relying completely on the DELTA Pro and DELTA Pro Extra Batteries to power everything including the refrigerator, air conditioning, microwave, and inductive cooktop. In the RV, we especially appreciate the AC pass-through mode, and the fact that we can charge via DC (solar) and AC (for example, via an inverter powered through the alternator) simultaneously. Our only wish is that EcoFlow would come out with a series of longer length cables to connect the DELTA Pros and DELTA Pro Extra Batteries so the units do not have to sit so close together. Overall, we are extremely happy with the products and responsiveness of customer service.

I received my delta pro from kickstarter campaigned. Used it as ups for my home network rack which powers 200w of network equipment (router, PoE access points, PoE cameras etc, plus cooling fans). During a power outage in the neighborhood, my unit stopped working and showed some error codes. EcoFlow was very quick to help and send me a replacement unit. Never had issues since. Have the smart home panel too, but that still needs to be installed.

I have been reading about possible outages coming our way so after doing due diligence I found Ecoflow. I bought one delta pro and liked it so much that I bought another Delta Pro, an extra battery, and two 400-watt solar panels. I have been charging my two refrigerators, my phone and laptop, blow-dryer and bedroom on my two delta pros with 650 watts all day long free of charge.

I got this Delta Pro and the extra battery when it was being crowdfunded on Kickstarter. So far it has been working very well. I haven't really tested it anywhere to its limits yet or even for the purpose I got it for, which is to run an electric cement mixer, because I haven't started building my off-grid house yet but I am hopeful and confident that it will perform as it should as my other Ecoflow products haven't let me down in the past (R600 Pro). So far I have charged some devices and run some appliances and it works well with no issues so far. The build quality is good and the handle that pulls out for you to roll it around is sturdy enough. I also appreciate the length of the warranty for the Kickstarter backers. This setup will be my plan b in my off-grid home as it can run anything I want and for now I totally recommend it.

Been running fully for just about a month, had a manual transfer switch and purchased the SHP 1 for the automatic switch over and was well worth it. Now running 2/3 of the house off battery/solar. Charge during the day and run house off batteries at night. When low solar production I have it set to charge on grid during off peak hours to lower costs. Getting full charge through the SHP 1 was a big boost from just plugged into the wall.

I received my EcoFlow Delta Pro about 6 months ago. It arrived well packed and in good shape, despite the outer box taking more than a few good hits. I’m very happy with the quality and functionality; when I get a second one, I will be able to effectively run the whole house, and with the solar panels be able to survive a grid-down situation. It’s heavy, but still quite portable, and the necessary accessories were all included. One thing I would like to see developed: to operate, it has to be in my garage where my breaker box is, exposed to less than optimal hot and cold temps. How about an insulated jacket with heat/cool abilities to keep the unit temp in a good range?

I bought the River Max first to see have the Smart App worked. It worked fine, and then I purchased the Delta Pro during the Kickstarter campaign. I tested it with two flexible solar panels, and it worked fine. Make sure the panels are compatible...most are. I intend to use it for 16 building portable solar powered docking charging stations for e-scooters for a non-profit. So far, so good!

I purchased the Delta pro during the Kickstarter and have had it for about 6 months. I'm using it daily with the double voltage hub to run the whole house (except a/c Heat pump) to offset my energy bill. I have each one connected to 5 100 watt solar panel. When I know a storm is coming I love the fast charging because if it's not fully charged I can plug it into the wall and finish charging in case of a power outage. Great product!
