€1.445,90 - €1.881,90
Tax included.

Full charge at low engine speeds: The Mastervolt Alpha alternator with integrated Alpha Pro III charge regulator has been specially developed for onboard use and delivers powerful charging current even during port manoeuvres or slow motoring. This means your batteries are charged faster – no matter how warm the engine compartment is.

Tip: You can obtain the appropriate bracket from your engine supplier or a Mastervolt technician. Some engine brands are already supplied with Mastervolt-compatible brackets as an option – it's worth checking in advance.
