Alfa Kompakto 28/110 kintamasis generatorius

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

This model operates at 24V DC and delivers 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 they are lead-acid or lithium-ion.

Yes, when paired with the Alpha Pro charge regulator, this alternator is fully suited for charging 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 cause overheating and failure of the alternator.

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 a clutch) depending on your mechanical installation.

A ribbed (or multi-rib) belt with the « PK » profile, suitable for a multi-groove pulley, is recommended. The belt must be able to withstand the total mechanical load of the alternator.

No, the Alpha Compact 28/110 is supplied as standard non-isolated, 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 bushing kit offered by Mastervolt.

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

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

The Alpha Compact 28/110 alternator weighs 7.4 kg.

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

No, Mastervolt does not provide mounting brackets. You must use the preinstalled bracket for 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 heat-limited, 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. As a general rule, the total mechanical-to-electrical conversion efficiency is about 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 run continuously in demanding environments and the high temperatures of boat engine rooms without performance loss.
