EcoFlow Delta Pro Ultra Home Backup Solution

Purchased EcoFlow Delta Pro Ultra Inverter/Battery Backup to hook up to my Home GenerLink backup solution installed by my local Electric Company. Hooking the GenerLink to the EcoFlow Delta Pro Ultra, then hooking my EcoFlow Delta Pro Ultra to both Solar Panels and a Wen 6800 Dual Fuel generator (Model #DF680IX) to charge the EcoFlow Delta Pro Ultra. I really like the EcoFlow system for home backup and looking to add another 1-2 batteries to existing EcoFlow Ultra solution in the near future.

Hi Key Largo Obx,

Thank you for sharing your experience with the EcoFlow Delta Pro Ultra. It sounds like you’ve set up an impressive backup system with the GenerLink, solar panels, and your Wen generator — that’s a powerful combination for reliable energy security.

Jam is a rockstar!!

Recently I purchased the Ecoflow Delta Pro Ultra. My contact Jam (did I spell that right) was quite excellent. She was both
knowledgeable and extremely patient. Having offered me a price and advice far superior to any other supplier i was more than happy to purchase from your establishment. In short high marks for both Jam and your company. I fully intend to further avail myself of
your companies services in short order.

Hi Ronald,

I can’t thank you enough for your kind words and for choosing Outbound Power for your EcoFlow Delta Pro Ultra. You did spell Jam’s name right — and you’re absolutely correct, she’s a rockstar! I’ll be sure to share your note with her; it will mean a lot.

Great company

I had a great buying experience. They were very helpful, especially Jam!!! I bought 3 EcoFlow Ultras with extra batteries and their prices were unbeatable. On top of that they even gave me free extra panels!!! Shipping was super fast, with no problems. Overall I had an excellent experience. They are my new favorite supplier!!! Thank you very much for your business.

Hi Aiezer,

Wow — three EcoFlow Ultras with extra batteries and extra panels! That’s quite the powerhouse setup, and we’re thrilled we could be part of building it for you.

I think that I did my homework on this unit and this package and I hope all goes as expected. More importantly I at this point I really wanted to say a BIG THANK YOU TO Bill at Outbound Power and His Staff. They made this purchase painless and a pleasure. Their customer service is top notch and their shipping extremely fast. They followed up on the whole process from start to finish. Also in doing my due diligence I found their prices to be better that any other seller out there it makes me feel confident that if I need any help or if I have any issues Bill and his staff will be there for me. I know that any of my solar needs in the future will be coming from Outbound Power. Thank you very much. MikeR
