Massive capacity back up my whole house This is a mature home backup package that can be connected to the household circuit, apparently serving as an alternative to the Bluetti EP500 and EcoFlow Delta Pro. I'm slowly falling in love with it.

I called Mango customer support first. I called Mango customer support first. They took my order number, email address, and phone number - and said they would verify my purchase and get back with me via email. My units had come without the power cords to plug into the wall outlet - to charge as needed. Customer service came through. They got the cords to me. I’m very happy about that. They were also good at communicating via email.

Mango Power E problem resolution. Professionalism, knowledge and Great Customer Service provided by Ms Vevina was wonderful. She did on line trouble shooting on my device, in no time I returned my device and had the new replacement delivered to my home!! Thank You Vevina for all the help and immediate resolution! Very much Appreciated.

Horrible company. Worse customer service I bought a $40,000 mango power m system with 40kwh of storage. They have apparently one employee named David. I knew I shouldn’t have bought a system from a company less than 2 years old. But anyways they haven’t helped me at all with the multiple issues I have. Can’t see one of the inverters in the app. Things trip when ac charging. I even made an appointment for a phone call with the technical team and they didn’t call

choosing between Union and E units at… choosing between Union and E units at the very start of the company start up was clumsy at best since the pros and cons of each were vague. Since it has now cleared up with precise descriptions the choice could have been wiser. The one possible strong point for Union is its ability to be wired into the home for total house backup, at some expense. By contrast E offers that too and with some more advantages.
