Alpha Compact 28/150 alternators are optimised to deliver continuous high power output in energy storage applications. Combined with Mastervolt 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.
Compared 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.
The Alpha Compact 28/150 alternator comes without a pulley.

Great customer service and competitive prices.
Beaver Easy Fin Spring Straps Quick Release Medium
Great company, fast email communication, and very quick delivery.
I was looking for a new wetsuit and found these guys online. They had the wetsuit I was after and there was a link to an interactive sizing guide to help me identify the right size. After ordering I received an email checking I had used the chart to make sure I was aware and avoid getting the wrong one. Wetsuit arrived a few days later. Cannot ask for more.
Small order, but never the less a very positive experience. My replacement fins straps were not delivered (Christmas time order) when I chased this with Russell, his email reply was instant and positive. A new order was dispatched and received a few days later. Highly recommended
