Mastervolt Alpha Compact 28/150A w Alpha Pro III Reg.

Alpha Compact alternators are optimized to deliver continuous high power output in energy storage applications. Combined with our Alpha Pro regulators, they create a high performance, plug-and-play charging solution. This combination is suitable for all battery types, including Lithium Ion.These automotive style alternators offer many advantages. Most manufacturers offer a second alternator option, better known as PTO or Power Take Off option. This provides a straight-forward way to add an Alpha Compact as a second alternator. Alternatively, the stock alternator can be replaced with an Alpha Compact to obtain a powerful, MasterBus enabled 3-step charger.High performance plug & play alternatorsCompared to conventional alternators, Alpha Compact offers lower weight, smaller dimensions and reduced fuel consumption. This is made possible by its open construction with double internal fans. An integrated temperature sensor controls the operating temperature.ModelsThe Alpha Compact series consists of 7 models in 12 V and 24 V.
