Hi, two questions: (1) Doesn't each Sunny Island unit already include a DC disconnect breaker for the connection to battery?
(2) Aren't those big DC breakers in the Outback boxes restricted for "vertical installation only"? I've got my own 3 phase Sunny Island thing coming up (maybe) so I look forward to these answers.
