Got a second Delta

I originally bought the Delta 2 Max with the plan to eventually get an additional battery. However I decided instead to get a Delta 3 Max. Either way would result in the same total watt hours…. But there were several reasons for additional unit instead of additional battery:

-now I have additional redundancy should a unit break

-I could solar charge one unit while other powers the appliances, and swap

-can place each unit in different parts of the house to avoid extension cords
