Have owned the delta pro ultra for over a year now and it does very well powering my home with the smart home panel 2. I have 2 ultras and have expanded the number of batteries to 5 for each unit with 6kw of solar, 3kw to each unit.

I'd like to have something other than a beach towel to cover this expensive device when it's not in use. Better yet, how about a cover that can be used while the device is operating, like there is for the other smaller units?

We have really been impressed with our DPUs and their ability to power our whole home during outages. To give you some context-we have 2x DPUs with 3 batteries each for a total of 36kW. Because of the location of our main service panel, we simply did not have the flexibility to get a SMHP2. Our basement is finished, our 200 Amp main panel is in the corner of our laundry room of all places. Right next to the dryer and washer (you can see the dryer in the pic below). It is crazy to me why they would place everything in that corner of the house when it was built back in 1993 but they did. I was quoted thousands of dollars to relocate my service panel and almost as much to install the SMHP2 and they would need to tear up some of finished basement walls. That was a no-go.
So we found some excellent sales with Ecoflow and another online retailer. We went with a simplified set up using the 50 Amp Hub, interlock switch, a double throw switch and 50-amp inlet. We run a 50-amp cable from the hub to the inlet. My wife did not want me to mount the hub on the wall, so I built a little stand for it. It works like a charm. Trying to find the limits of our set up this past weekend, I connected the DPUs and ran the entire panel, no managing loads at all. At one time, we had the heat on upstairs and downstairs (two 2-ton heat pumps), the oven, lights, water heater came on as people showered, TVs, etc, etc, etc. Basically, we had a full load of house totaling 10kW+ (pic below) and the DPUs did not miss a beat. This tells me that for extended periods of outage and managing loads, we can definitely go a day+ using these if need be. This gives us some great flexibility for power back up between using our duel fuel generator and DPUs.
My plan for extended outages is to use my external inlet for my generator during the day and in the evening shut it down to secure it. Then switch to the DPUs inside for overnight to avoid worrying about a running generator. Our goal is to get 4 more batteries and get to the 2 stacks with 60kW. Eventually if we get the SMHP 2 installed, we'll see about getting the rest. I LOVE THESE!!!

Very impressive product! Recently bought this unit and very satisfied so far with the performance and the pre product support. With Helene, we lost power at midnight for around 10-12 hours. Instead of having to get out the generator in the early hours and fire it up, I easily and simply plugged the 30 AMP cord into the Delta Pro Ultra and hit Protran transfer switches. Presto..it was like magic and worked like a champ! Easily powered Frig, small appliances, including microwave (power hog), TV, ceiling fans and a portable AC to keep things cool and was at around 60% after 4 hours.
