Mr.

Great kit. If anything constructive criticism wise, I would suggest someone review the orders to ensure they make sense. I ordered 4 solar panels and only a duel cable splitter....had to go back after delivery and order a quad cable connection. Other than that it was extremely easy to set up and get going. My garage freezer and refrigerator are now permanently off-grid and I have portable power in an emergency! Great stuff!!!

Great System!

We love our EcoFlow Delta Max 4000 Quad Kit with 4x200 Watt 12v Solar Panels. Set it up to evaluate and everything worked great! The Delta Max ran 4 appliances just fine and the solar panels charged the system back up in 12 minutes without a hitch!

EcoFlow DELTA MAX 6000

Arrived faster than expected. One panel was broken and the company replaced it quickly. It charges very fast.

Expensive, But They All Are. This Is Easy To Use.

This is really easy to use. You don't need to be an Electrical Engineer to set it up. Received it pretty quickly. I recommend it.

Amazing service

Best ever support with videos and rapid response and delivery of products. They answer the phone and talk with you. So far running my freezers off the very simple and powerful delta eco flow as I start my solar journey.

Excellent

Product came on time. Even though I already have a house generator, I bought this to extend the time I run my refrigerator and Freezers. I live in Florida and if we get a bad hurricane I will be totally prepared. Right now I am testing the load on the batteries. I am very pleased with the results.

would do it again

great to work with. The echo max does all it is advertised to do. The Titan is a huge disappointment. You have been a great help setting up and answering questions. Thank you for your product. Wish I had known before about the suitcase panels. I would have purchased them instead of the regular panels and legs.
