Earthtech Products is my go to for EcoFlo power packs. They are easy to work with and stand by there products.

Earth Tech had a great deal on this kit - well worth the money. And, their representatives are extremely knowledgeable and will help walk you through the process. I will only buy from them!

I am taking the time to write this because I received an outstanding customer service. They help me all the way with information about the product and shipping service. I felt secure to invest my money in the product. Thanks. (Chistopher was my customer rep)

Purchased for flexibility during Emergency Backup situations (1 day or less).... This setup pairs well with the EcoFlow SHP 10 circuit single phase setup. A single battery can handle everything on 110v without issues. Just keep in mind if you choose to go this route each battery will have an AC current draw which requires the batteries to be charged about every 4.5-5 days(EcoFlow tech states 33w per hour). After learning this about the system, it seems that the battery and smart battery would be a better use case for single phase to extend the time between discharge. Recharge automations through the grid are possible. The system has been working as expected. I'm allowing for a break in period before committing to other products such as solar panels and/or smart generator, but the peace of mind it adds is priceless.

My basic use case is for home battery backup on my existing solar setup. I can hook this up, 240v split phase, 2x delta pro through double voltage hub to generator transfer switch which will power the whole house. Or you can do further with critical load circuit with manual transfer switch panel such reliance pro/tran. BUT to unlock more use cases (electric rate arbitrage, automated certain circuit to use battery, faster charging on both battery, automatic battery backup on power outage, app control etc), It will be best to use these 2x Delta Pro with Ecoflow smart home panel.

Purchased for my 2 DeltaPro - so far working as described.

Generator is working as advertised. Depending on your application a person could be disappointed. I now realize that 1 pro and additional batts might be a better investment foe using as power for everyday. This is a good option for someone not capable of building a solar charge controller and server rack battery system.Pretty happy overall.
