I've only had the PRO for a week. Easy set up and looks to be of excellent quality. The only negative thing I have to say, is that the PRO does not provide a strong ground requiring an additional adapter to be purchased. I think the adapter should be included with the PRO without an additional cost since the PRO doesn't work for my application without it.
Best packaging I have ever received! Simple set up. I had watched a lot of videos before the purchase. I'm an electrical contractor and do about 30 Generac generator installs per year and hopefully going to get a few people to try your product. So far it performs as expected. I'm using it 24/7 to power 1 of my circuits in my home. Using 3 panels to charge when the sun is available. I do wish now that I had waited for the new model to come available but maybe in the future.
I purchased my Ecoflow Delta Pro a couple of weeks ago. That and a couple of solar panels were shipped quickly, less than a week. The only drawback is that it wont charge or put out power when it's very cold. I live in southern Utah at about 7300 feet above sea level. I hope to remedy this with a low watt heating pad under the unit. Other than that I am very impressed with the Delta Pro and plan to order another one with another solar panel. I kicked off the main grid breaker and back fed my 200 amp panel with the 30 amp RV outlet on the Delta Pro. Being 120VAC it would only run half my house but would do it well. I plan to purchase another one with the 240vac voltage hub to I can run most of my house being discreet on what I run and what I don't run all the time. I'm happy with the Delta Pro, it has pretty well replaced my 6.5 KW diesel generator. The Delta pro is backup power for my HAM radio equipment too. I would highly recommend the Eco Delta Pro.
In received my Delta Pro about a month ago and the solar panels shortly there after. I charged it up from the 30% it came with via AC and immediate put it to a test with my fridge and various other items-phones, I-pads, electric heater-and was very pleased. I purchased the unit primarily for the refrigerator and freezer, which it could run for days. But I see the possibilities for use are many. I haven't had the chance to utilize the solar panels yet due to weather. The delta pro gives me a more secure feeling in these windy, winter months.
