I bought several items just before hurricane season really set in, Florida has plenty of sunshine and humidity so my purchase of two wave 2’s was on point. Making electricity from the sun is not an easy job, dii uh e to the weight of each item or the repositioning of panels to catch the peak sunlight at the time. I used my 220 solar panels to charge each machine. They worked well but due to uncontrolled factors, I could only get 190to 200 watts from the two working together. It took awhile to get three machines fully charged, three days and then using grid power to finish. Granted the delta pro started out flat. So no wonder. Time was of the essence as you can io so to finish with the grid was a no brainer. With all systems fully charged we were ready for the onslaught of Helene. Fortunately for us we live inland 5miles so the now famous storm surge was far away. The wind is another with gust reaching upwards of 75-80 mph, and the storm when it was directly across from us was still 50miles away , headed to Big Bend to make landfall We lost power within hours of the first gusts of wind. During the next 24 hrs rain and wind snapped trees and limbs and we would have been in the dark save for our backup’s. All devices were on, cooling us through the night running internet , as long as that lasted, and cooking our meals the next morning. Considering the circumstances and my own inexperience, the system did their job. I will buy an extra battery for each wave 2, to get us through the night without stopping. But being spoiled by the convenience of the grid, I welcomed it back. Overall it was a good learning experience and I will be reassured that the EcoFlow system will be there ready to go again.
