Features

  • One Powers All. The unit of DELTA Pro Ultra whole house generator includes an inverter and a battery. One inverter supports 120V & 240V and has an exceptional 7200W output, allowing you to run almost any heavy household appliance, even a 3-ton central air conditioner. Triple the inverters for an incredible 21.6kW AC output, allowing you to live life to the fullest even during an outage. The electric generator achieves a total 7200W output even during charging.
  • Strong Power Security. Scalable from one battery of 6kWh, two days of essential power, all the way to 15, it multiplies the energy to a gigantic 90kWh. For a standard North American household, that's over 30 days of essential power secured.
  • Multi Ways to Charge. One battery of 6kWh can be fully recharged in 2 hours. Faster than any other 6kWh solar generator. Users can choose among electric vehicle piles, solar, wall outlets or outdoor generators for charging.
  • Customize Your Home Power. Use the EcoFlow app to priolritize specific circuits in your home, extending your backup even longer. For more than just blackouts, it intelligently analyses your home power usage to offset peak rates while utilizing solar to lower energy bills.
  • Uninterrupted Life. Online UPS with 0-ms transfer time, offering 24/7 protection for sensitive electrical devices against power disturbances or grid failure. All fans are off for the first half hour of outputting 2000W, giving you absolute silence for tranquility in everyday life.

    • Excellent backup solution for diy.
Style: DELTA Pro Ultra
Review Image by IT GUY
I have this paired with an ecoflow panel to provide backup power for my fridge, freezer and furnace during a power outage and it works perfectly. I bought 3 batteries for a total of 18KWh which will keep me online for 2 days. If you pair it with some solar panels, you can setup a cycle where it will recharge from the sun during the day and discharge at night. You can also plug a generator into the ecoflow panel as a backup if you dont have solar or the panels are snow covered. This solution is also half of the cost of a tesla powerwall with almost double the capacity. Plus you can easily expand your storage capacity at will just by plugging in more batteries. I paid 10k for the whole setup and got 3k back from the government rebate. ... show more

    • Battery backup, Inverter, solar charge controllers all built in, all working together
Style: DELTA Pro Ultra
Everything arrived in less than 2 weeks without any problems. Connected this system to an existing 10 circuit transfer switch. Added an extra battery (now have 2), added 8 x 195-watt solar panels. Batteries came with a 30% change. Used solar and gas generator to charge to 100%. Then ran my 10 circuits (everything we must have) for over a day with solar disconnected. With solar connected (and some sunny days) we could run for a few days easy. Overall, very happy with the system. Had a chance to use their support and warranty recently. My 14-yr old gas generator died. So, I tried charging by plugging into a 110V outlet which didn't work, no error or indication why. Contacted support via email (emails are answered overnight) and got a canned response the next day that had me try the normal basic stuff. I answered back that none of that resolved the problem. They then wanted a detailed description of the problem and to upload a video of the failing phenomenon and also to try different outlets, which I did. After a couple of days, they determined (educated guess) the problem was the AC power cord and were sending me a new one. That took over a week and did noy fix the problem. I then asked them to replace the controller / inverted. The next day they informed they would send me a NEW unit as soon as they received my unit. They provided a FedEx shipping label. Sent my unit back and received the new replacement in just over a week. So why 5 stars? They replaced my unit with a NEW unit. I also found out that all the outlets I tried were unused and on a GFI circuit which popped as soon as the AC cord was plugged in, probably a grounding issue. AC charging worked fine on a non GFI outlet. Their products are great, and they honored their warranty. Uploading a video was a little strange! ... show more

Great for a battery backup system for servers and network equipment. And about a 3rd the cost of an APC Battery Backup system with comparable backup time.

    • Extremely Disappointed — Poor Customer Service & Cheap Presentation
Style: DELTA Pro Ultra
Review Image by Georgia V
After purchasing this product through Amazon, I later discovered it was being sold cheaper elsewhere. I reached out to the company hoping to buy an additional item so they could offset the price difference instead of issuing a refund — but they flat-out refused. What really changed my opinion about this company, though, was their lack of professionalism and attention to detail. They don’t even include a printed manual with a $7,000 product! Instead, they expect you to go online and read a digital version. But here’s the kicker — when you actually need the manual, there’s likely no power. How exactly is an online manual supposed to help in that situation? When I called to request a printed manual, they literally printed out the PDF themselves and mailed me a low-quality, unstapled stack of papers. Unbelievable. You’d think a company selling high-end products would take pride in the customer experience, but this felt cheap, dismissive, and completely unworthy of the price tag. What kind of Mickey Mouse operation thinks this is acceptable for a $7K purchase? And now, after weeks of back-and-forth, EcoFlow has given me three or four completely different answers to the same question about product compatibility. Every email comes from a different person, each with a completely different explanation. The level of misinformation and disorganization is astonishing. It’s clear there’s no consistency, no accountability, and no genuine concern for customer satisfaction — just the kind of careless, impersonal service you’d expect from a company operating under a detached, overseas mindset. At this point, I wouldn’t recommend this company to anyone looking for reliability, transparency, or professionalism. ... show more

We bought this for our RV, but we've already put it to use in our home during power outages. It charges up fast and holds the charge even when sitting, unplugged in our home. Easy to use - just plug it in and let it charge up. This is going to be perfect for our needs.
