Perfect solution for a tiny house
Impressed with the turn key connectivity and function. Added this as an initial package purchsse. Saving to purchase battery to be the whole house power ststion for my tiny house. Currently using the Delta Pro 3 with 8 keh syorsge plus two Delta 3+ systems and two Delta 2 with Delta 2 Max battery systems. Been off grid for two plus years with dependsble power. Glad I decided to use EcoFlow for all my power consumption.

Well worth the investment
I bought 4 extra batteries almost a year ago and have cut my electricity usage by 90%. They have worked flawlessly and have exceeded my expectations.

Plug and play!!
Got it delivered, plugged it in, and the system started charging it right up! I love that there's no panel on the front (that was confusing, with the Delta 2). My only question - WHEN WILL YOU HAVE MORE? I want to order a 2nd one!
