Alpha Compact 28/110-es generátor

This is a high-performance alternator designed for marine environments. It delivers 110A at 24V to ensure fast and continuous charging of service and starter battery banks, even in high-temperature engine rooms.

This model operates on a 24V DC voltage and provides an output current of 110 amperes (110A).

The Alpha Pro regulator applies a precise 3-stage charging algorithm. This is essential to maximize the performance and lifespan of your battery banks, whether lead-acid or lithium-ion.

Yes, when paired with the Alpha Pro charge controller, this alternator is perfectly suited for recharging Lithium-Ion (Li-ion) battery banks as well as lead-acid batteries.

The Alpha Compact 28/110 alternator requires clockwise rotation (the direction of the clock hands) when viewed from the pulley side.

The clockwise rotation direction is strict because it ensures the proper operation of the internal cooling fans. Incorrect rotation would lead to overheating and alternator failure.

No, this specific model is supplied as standard without a pulley. You will need to add a compatible pulley (6 or 8 ribs, standard or with clutch) depending on your mechanical setup.

It is recommended to use a ribbed belt (or multi-rib belt) with the "PK" profile suitable for a multi-groove pulley. The belt must be able to support the total mechanical load of the alternator.

No, the Alpha Compact 28/110 is supplied as standard uninsulated, meaning the ground (negative pole) is connected to the metal housing of the device.

For an isolated installation (often required to protect sensitive onboard electronics from the engine), you must use the optional insulating sleeve kit offered by Mastervolt.

The part number for the insulating bush kit compatible with the Alpha Compact 28/110 is 48420242.

Using insulating sleeves reduces the diameter of the alternator mounting holes. For example, an M12 hole is reduced to M10, and an M10 hole is reduced to M8 when installed on the mounting bracket.

The Alpha Compact 28/110 alternator weighs 7.4 kg.

Yes, it can absolutely be installed as a second alternator dedicated exclusively to charging the service battery bank, in addition to the main engine alternator.

No, Mastervolt does not provide mounting brackets. You must use the pre-installed bracket on your engine (PTO option), a replacement kit suitable for your engine, or have a custom bracket fabricated by a qualified professional.

Unlike standard alternators, which are often limited by heat, the Alpha Compact series is designed to maintain optimal mechanical and electrical efficiency even at full load and high temperatures.

Yes, Mastervolt offers multi-groove pulleys compatible with this model, available in standard version or with a clutch (freewheel pulley) depending on your installation requirements.

The alternator draws power from your engine to generate electricity. Generally, the total mechanical-to-electrical conversion efficiency is around 50%. Ensure the engine has sufficient power reserve to drive the alternator at its rated speed.

Yes, the Alpha Compact 28/110 is specifically designed to operate continuously in demanding environments and the high temperatures of boat engine rooms without performance loss.
