I love this generator! I currently use it as my QUIET indoor generator when power issues arise. Also great to take on trips or for outdoor camping. I couple up the 220 Watt bi-facial solar panels and I am never without power. This thing is a beast and I also have the Delta mini for super portability or smaller jobs. Great customer service with phones answered very quickly and very different than all those reviews that knocked the customer support. I give them an A+ for customer support. Don’t wait because these solar generators were not available at the end of 2021!!

I live in southern California where the power company turns off electricity every time the wind blows. I run a small business out of my home with remote workers on virtual machines that I host in my server closet. My Delta Pro allows my workers to have access to their workstations whenever the power goes out. The Delta Pro is great because I can charge with solar and the smart generator meaning I can keep the servers running for more than 24 hours in any given outage. The app is powerful and allows the inverter to be set to always on preventing accidental shut off. The unit is heavy but the Delta pro has an extendable handle and rolls on wheels making it easy to move around. The features, expandability, and available accessories make the Delta Pro my favorite solar generator. I have the smart generator and the 400 watt solar panel. Build quality, shipping materials, software, and support are all excellent.

We bought the Pro after years of using the original Delta. We needed 2 Pros to provide 240v for our well pump (the rest of the sub panel only needed 120v). There was a problem with 1 of the Pros, but it was replaced without fuss. That is the service you need when investing thousands in backup power. Great system & company!

I purchased a month ago drove across the US, and the only thing I noticed is that the cables plugged into EcoFlow Deltra pro vibrates lose occasionally. No harm, but wish cables were designed differently so not to stick out from the device. Easy to get dislodged. Othe wise so far works as promised.

I absolutely love my Delta Pro. I have been researching solar generators for a few years now and I was looking that offered a lot of power with room grow if needed. I was also hoping for something that was universal so I can use it different situations since these batteries can be very expensive. There are a lot of great options out there but I am so happy that I went with the Delta Pro. It has a substantial amount of ports and I love that Ecoflow added the 30 amp Anderson port so I can easily hook up a fuse box with additional items to it. I also love the SUPER FAST charging and the app that allows you to turn ports on and off as well as customize things like power input. It is on the heavy side but it is technically lighter and more portable than trying to build the same setup using battle born batteries :) . At the end of the day, the cost is well worth it for the quality and the technology.

We lose power all the time and I needed a backup system for those moments we lose power from a few seconds to a few hours and maybe help with offsetting my monthly bill. After the last hurricane and being without power for over a week and having to refill my generator every 11-12 hours I needed to find another way. I looked into many name brands, found out my insurance would drop me if I put solar panels on our roof so I needed to come up with another plan. I didn't need a full system, or have a system where the local electrical company could remotely turn off my system, but needed a system in the middle that could also be portable. So I found this things called solar generators and started looking into them, all the companies have there own +/- and EcoFlow was the winner for all the things I needed. From the install 3 months ago we have lost power 2 times, ones for almost 2 minutes and other for around 3 1/2 hours. My wife and I didnt even know we had lose power until we had a phone call asking if we had. My answer, no idea maybe, let me check my APP. I finished phase 1 3 months ago with a Home Control Panel, 1 Delta Pro 3.6 and 4 solar panels and a double pull switch that makes it super easy for my wife to change to generator power to charge the Delta Pro when am on the road if needed. The design below is my personal design that gives me backup for backup. I can recharge my Delta Pro via of: - Grid - Solar - Generator AMAZING product and I look forward to getting 1 more Delta Pro 3.6 and 2 Delta Pro extra batteries within the year with 4 more solar panels. The only Con I see is, if a main Delta Pro goes out for whatever reason and you have 2 extra batteries your dead in the water. So you're better off getting 2 Delta Pros 3.6 per leg for the Control Panel and adding what you need from there so if your main units dies you can use the extra battery on the other leg giving you house power. Highly recommended

I use this for my van conversion and it works great. Wish the remote could connect to more than one unit. And wish there where more than one input for dc charging (from solar and from car charger). But other than that it’s great. 960 watts of solar no problem.

I got a Delta Pro through the Kickstarter campaign for emergency power, and it's great overall! It arrived undamaged (it weights 100 pounds!) and charged from 30% to 100% in less than 2 hours on a 120V AC outlet. It has powered everything I've plugged into it, including a freezer chest, kegerator (for emergencies), and old full-size fridge/freezer. It can power all 3 for about 24 hours on a single charge with no solar input.

We purchased the Delta Pro and extra battery last winter as a backer on Kickstarter. We initially planned to use this device as a backup in case we lost power to our home. I work from home and need to have internet and power to my home office at all times. We recently lost power for four hours and the battery handled all of my home office equipment as well as other appliances in the home with ease. Since these are portable, we plan to use these on our next camping trip along with a 300w solar panel. Highly recommend the Delta Pro.

We've been wanting portable batteries for a long time so we purchased two Delta Pros to run our 240V pump, once we receive the Double Voltage Hub - due tomorrow, and to act as back-up during CA Public Safety Shut-offs and winter storms. With a L14-30 cable we will connect directly to our manual transfer switch to run the house. Recharging the unit can be set from 200W - 1800W AC but I haven't tried the fast charge yet. To stop charging before fully recharged you must disconnect the AC plug. Note also that you need to unplug the AC to the unit to turn off the Delta Pro. EcoFlow recommends you do not leave the unit(s) plugged in all the time as this may cause degradation of the battery over time. This 70 year old is able to wheel the Delta Pro around - portable but a bit heavy at ~100 lbs. My husband and I can lift it into the SUV and take it on trips. Solar panels are on the way. The fan is a little noisier than I expected when recharging, but not bad. Delta Pros are a great value for the price!
