Pierre Joy
Enables 2 EcoFlow Delta Pro to deliver split phase

I purchaed 2 EcoFlow Delta units and needed the Double Voltage Hub to feed the transfer switch.
The double voltage hub worked and has been in use to provide backup power during a power outage.

Fidelson Cale
Doesn't let me charge my Electric Vehicle (EV) - Grounding Error - NOW IT WORKS!

Everything worked great! Very happy now with this purchase

Do your research for the product

I have tested this running the house in an off grid mode. The dual coltage hub will not balance loads, it is not designed to do that. The dual voltage hub is not designed to charge the delta pro's that is the reason for no rating under that heading. If you want a backup whole house source this is a very good combination, thoroughly recommended.
