I bought my delta pro and 1 extra battery on kick starter as I thought it was great technology. After receiving it, I was blown away. This system is amazing and to boot the customer service has been top notch. They have always gotten back to me within 24 hours with an answer to my needs and concerns as this is all new to me. I have been running it nonstop since I’ve had it taking 2 refrigerators, a freezer, all our internet gear, and our basement circuit off the grid. I’ve seen my electrical bill go down about 40.00 a month. If you are considering this equipment don’t hesitate as I’m a very honest person and would be the first to say if it was junk.

I bought the Delta Pro for my elderly brother that can be used for his medical equipment in case of a power outage. I bought recommended solar panels to keep the unit charged. The app is great for this device to monitor the system. Now I am not worried about not having power for my brothers medical equipment.

Traveled first year with our RV all the way from Virginia to Colorado…. Boon dock a couple of places and it was darn hot!! No power. We had our portable fan as to minimize RV battery but just could not cool it enough. I have added and upgraded our RV battery since last year. In addition I purchased the ecoflow pro, ecoflow pro extra battery, ecoflow portable generator, and also the ecoflow 400W solar panel. I have tested it out and so far it works pretty darn good. Granted it will provide only 6 hours to power essentials and running one of 2 15k BTU AC. Of course I had to add softstart to the RV AC (very easy install). I plan on buying additional extra battery from ecoflow and of course double capacity to the RV batteries as well. Anyway for a beginner RV’er this solved my problems for cooling without excessive manipulation to the RV power system. I just used the 30A converter to 50 A directly to RV power input…and will power on for at least 6 hrs without the 400w solar and portable generator (haven’t tested generator yet) connected. We will see how it goes this year but so far I am very happy with our ecoflow system. Side note I build solar panel holder with pvc wood as it is light, flexible, and easily transported in RV…set it up so it will take less than 5 min to set up.

I bought a delta pro, extra battery, smart gen & solar panel and so far had 5 power outages some short some for up to 2 days worked perfect powering: refrigerator, PC & floor fan already used both input from smart gen and ac input from a second gen to charge before night and charged pretty fast. Great so far keep up the good work guys.

I did a lot of research before purchasing the Delta pro. First off, I realized that a solar generator was clearly the way to go for back up emergency power. They offered so many advantages and eliminated so many problems over fossil fuel generators that they are too numerous to list. Once I realized that solar generators had finally reached the necessary storage capacity and power, all the reviews of the Delta Pro showed it was the clear winner in its class for overall quality, performance, reliability and value.
Since starting this project, I decided to advance from just getting emergency back-up power to supplementing my electric usage with the Smart panel and two Delta Pros.
Once my electrician installs the Smart panel, my plan is to run my AC unit, refrigerator and other high wattage appliances with my Delta pros during peak power usage periods.
The next phase of my plan is to add Extra Delta Pro batteries and some solar panels. Once my Smart Panel is installed, I will provide updates on how everything performs.
So far everything I’ve tested on these units have had excellent results. They easily handle all power demands and last a long time.

I’ll start by saying I’m really glad I purchased the Delta Pro and Extra Battery x 2. I have a little over 1,100 W (three 370 W panels) on my shed and have been utilizing the Ecoflow app and remote to control my appliances (from hair dryer, electric kettle, mini dryer, vacuum, power tools, etc…). The app really makes it easy to monitor solar input and trigger AC when not near the unit or remote. Build quality is fantastic and while noisy when hitting 900+ W of solar input, I’ll take a noisy cooled unit over a cloudy day with a quiet unit. I’ve also tested and used the batteries to charge my EV (using bonded plug) when I have more power than I know what to do with knowing the next sunny day, I can get close to topping off. Looking to have a nice long relationship with the Delta Pro with the battery chemistry being LiFePO4. Thank you Ecoflow for selling such a great piece of tech! Leaves the rest of the competitors in the dust. Lastly, my two gripes are 1) price (can’t wait for this to get more affordable *hopefully soon*) and 2) when can we utilize some kind of grounding adapter on the double voltage adapter so the EV can charge at 240V at 24A?
