The verdict

Identical on every published parameter

All 21 comparable parameters agree, with 12 more left out because at least one datasheet does not publish them. Two records this alike are usually one battery sold under two names, or two stack sizes of one system - decide on price, on the warranty terms and on which inverters each one is certified with.
