Style: DELTA Pro Ultra+2X125W*4


Features

  • Charge Anywhere. Replace your outdoor generator with clean, renewable energy. A single 125W solar panel has a high conversion efficiency of up to 25%, and 4x125W solar panels can fill DELTA Pro Ultra in 15.4 hours, 8x125W in 7.7 hours, 12x125W in 5.1 hours. Suitable for emergency power outages at home or during camping.
  • 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 6144Wh, 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 6144Wh 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.
  • Light and Durable. The 400W Solar Panel is foldable and comes with an adjustable carry case. Weighing in at only 16kg (35.3lbs), it can be easily packed up and carried with you, no matter where you go. It also comes with a IP68 Waterproof rating, meaning it is dust and water tight.
  • *Kindly remind that the inverter, battery and solar panel will be shipped in separate packages.

  • Well worth it and awesome
Edit/Update: The generator adapter only works for charging the unit, the plugs seem to have extra connectors to tell the unit what it can do with said connector. I would have to get the hub for it to use the main input and output. I went with plugging into the front 240v output and running it into a breaker box. Just a heads up to anyone with the same idea I had. The delta pro ultra is awesome and the solar panels are powerful. I have this powering my shed. I mounted my panels to the roof with some brackets I printed (even though these are really meant to be setup on the ground and portable. It was a prime day buy and it's where I needed them :p) I have it charging my ego mower with 6 10ah batteries and it does great. I also have it powering a sparkfun mosaic X5 for my personal RTK corrections source. I've ran my table saw and chop saw off of it without any issues, just like plugging into a regular wall outlet. I'm gearing up to install some outlets and hooking them up through the main input output port. I wish I had more batteries but honestly the single unit with one battery has done everything I need for in there. It's definitely a chunk of money but it's quality and customer service you are paying for. I had one panel cracked out of the eight and they sent a replacement without any hassle at. I greatly appreciate it EcoFlow. I'd give this more stars if I could. Just a heads up, it's bigger than it looks on the web and it's heavy. Don't do what I did and move it in to position by yourself. Next order: a pallet of Aleve and Tylenol. ... show more

  • Excellent customer service
Delivered fast with one solar panel damaged by shipper. Contacted ECOFLOW via email and got a fast response. Should have replacement panel soon. Will by a second unit once my house has the required hardware installed System works perfectly, currently using it to top up my Tesla
