High-efficiency alternators (APS and Ocean Planet Energy brands) have three key performance advantages: high maximum output (typically rated when cold but drops as internal temperature exceeds 100°C requiring efficiency focus), high efficiency ratings around 70% (vs typical automotive alternators at ~50%), and critically, the ability to ramp up output at low RPMs rather than requiring 2000-3000 RPM to reach full output.

“the maximum output which is typically speaking for these alternators are radio when they're cold well when you run them hard within five minutes they're uh up to the case is probably up to well over 100 degrees... they ramp up their output at low rpms yeah especially if we're battery charging at anchor”
