Yes, and it's your call as skipper as to what is "absolutely necessary."
It's easier to ask forgiveness than to seek permission.

Just got back from the marina, changed the battery charger over, paid the
next month's slip fees. While I was in the office, asked the girl for a
copy
of the marina rules. It states that sailing in the marina is prohibited
except when "absolutely necessary". I would venture that not having
auxiliary power to get back in would make sailing "absolutely necessary".
