I can't find anything that suggests they have an advantage in any area that matters (technology, reliability, proven track record, necessary capital). Tesla by definition has a more proven track record with the reliability of its battery systems...
I guess several of Tesla's top execs in Europe leaving for Sonnenbatterie a few weeks ago wouldn't have done the move if nothing interesting was brewing at Sonnenbatterie...

They had enough insider knowledge to judge both product offerings.
Besides I don't understand why everyone is so focused on just one competitor. It's true that Sonnenbatterie was a pioneer in the field, especially for residential solutions. But there are now dozens of competitors globally in the ESS/storage field, including Tesla's own supplier Panasonic. Most of them have already been on the market for some time.
Finally, ESS/local storage batteries often have very different requirements than EV batteries. Tesla has no proven track record in this space.
