There is a lot to I need to learn about solar power but so far so good with this power station. I do like the Ecoflow app and the delta 3 ultra plus. It is an impressive unit. This unit manageable. I really wanted the Ecoflow delta pro 3 but was afraid of the extra weight. As heavy as it is with the wheels I would still consider it portable as necessary. I am pleased to have found Outbound Power. They also had the best price on the unit. Delivery by Fed Ex went smoothly.
Thank you for the thoughtful feedback. We really appreciate you taking the time to share your experience. There is definitely a learning curve with solar, and it sounds like you are off to a great start. The DELTA 3 Ultra is an impressive system, and it is great to hear the size and mobility are working well for you. Glad to hear the app experience and delivery both went smoothly as well. We are grateful you found us and truly appreciate your support. Please let us know if we ever be of further assistance!
