Couldn't ask for a better alternator this will take anything you throw at it and my system is over 2000 watts and I barely go under 14.2v at full tilt not to mention excellent build quality! I won't run anything else after seeing how well it performs...

Mechman S Series Alternators
The S series family of alternators offers large case alternator performance in a compact package. Highly efficient, these 6 phase alternators use less horsepower per Kilowatt than conventional 3 phase alternators. 12 press fit diodes, twin rectifier plates, and highly efficient twin internal cooling fans make them durable in any application. Smaller, lighter rotors and reduced rotating resistance make them an excellent choice for high RPM or racing applications. Like their big brothers in the Elite series, the S series have hairpin stators and high pole count rotors that create much less Electromagnetic noise than conventional 3 phase alternators.
