Detailed description

Mastervolt Alpha Compact 28/150 yra aukštos kokybės energijos įkrovos alternatorius, skirtas laivams su didelės talpos 24V baterijų sistemomis. Išvystantis 150 amperų srovę, šis modelis užtikrina greitą ir optimalų įkrovimą net esant žemam variklio sūkių režimui.

Kompaktiškas dizainas ir galios/svorio santykis

Skirtas nuo klasikinės Alpha serijos mažesniu užimtumu, Alpha Compact modelių šeima sukurta specialiai įmontuoti variklio skyriaus ribotose erdvėse. Sveriantis tik 7,9 kg, 28/150 modelis pasižymi išskirtine galios tankumo charakteristika. Vidinė konstrukcija užtikrina efektyvų šiluminį aušinimą, leidžiantį išlaikyti aukštus įkrovimo srovių lygius be generatoriaus perkaitimo.

Sistemos integracija ir suderinamumas

Šis konkretus modelis tiekiamas be pulio, suteikiant techninį lankstumą pritaikyti individualų pulį, pvz., daugiagrandę (serpentininę) diržų sistemą, kurią galima tiksliai suderinti su jūsų variklio mechanine konfigūracija. Norint pilnai išnaudoti jo galimybes ir užtikrinti baterijų (ypač litiojoninių sistemų) saugumą, šį alternatorių būtina jungti prie išorinio įkrovos reguliatoriaus, pvz., Mastervolt Alpha Pro, garantuojančio 3 pakopų intelektualų įkrovos ciklą ir griežtą sistemos šiluminę apsaugą.

Expert review

Pol CONIN

Digital Manager

« Maximum power density for high-capacity battery banks »

The Mastervolt Alpha Compact 28/150 alternator is a must-have choice for modern vessels, particularly those equipped with high-acceptance Lithium-Ion battery banks requiring very high charging currents. Its ability to deliver 150A at 24V in such a compact package (7.9 kg) solves the space constraints of today’s engine compartments. Being supplied without a pulley is a genuine technical advantage for professional installers, allowing precise adaptation to a serpentine belt drive—essential for transferring the required mechanical power without risk of slippage. Paired with the Alpha Pro regulator, it turns the propulsion engine into a highly efficient and secure DC generator.

Frequently asked questions

Need help? Contact us

What is the weight of this marine alternator?

This alternator weighs 7.9 kg.

Why is this alternator supplied without a pulley?

This alternator is supplied without a pulley to allow you to install the model that exactly matches your belt type and engine configuration.

What type of belt is recommended for this model?

To handle a 150A load current, a multi-groove (serpentine) belt is recommended to prevent slippage and ensure optimal power transmission.

Do I need an external regulator to operate this alternator?

Yes, this alternator is designed to be paired with an external charge regulator, such as the Mastervolt Alpha Pro, to ensure optimal charging and protect your batteries.

Is this alternator compatible with lithium batteries?

Yes, this alternator is compatible with lithium batteries when paired with a suitable external charge regulator.

Does the alternator charge effectively at low engine RPM?

Yes, the Alpha Compact range is designed to deliver high charging current even at low engine RPM.

Can the Alpha Compact alternator replace my original alternator?

Yes, it can replace your original alternator or be installed as a second alternator dedicated to the service battery bank. Since this model is supplied without a pulley, you will need to provide a pulley suitable for your installation.

How does the alternator manage heat generated by high charging loads?

The alternator is equipped with internal fans that provide efficient cooling. This allows it to sustain a continuous charging current of 150 A without overheating.

What is the battery bank voltage compatible with this model?

This specific model (28/150) is designed to charge battery banks operating at 24V.

What is the maximum current output of this equipment?

The alternator delivers a maximum output current of 150 amperes.

Is it easy to install in a small engine compartment?

Yes, the Alpha Compact range is designed with a compact footprint to fit in tight engine spaces.

Can it be used with lead-acid, gel, or AGM batteries?

Yes, it is compatible with these battery technologies (lead-acid, gel, AGM) as well as lithium. The external regulator will adapt the charging profile to your battery type.

Is specific ventilation required in the engine compartment?

Yes, good ventilation in the engine compartment is recommended to expel hot air generated during operation and optimize alternator performance.

What is the main difference between the classic Alpha series and the Alpha Compact series?

The main difference lies in the format. The Compact series offers reduced footprint and lighter weight compared to the classic series, while maintaining high charging power.

Is the Alpha Pro charge controller included in the box?

No, the Mastervolt Alpha Pro III charge controller is not included in the box for this model. The alternator is however sold without a pulley.

Is it compatible with marine engines of all brands?

It is compatible with many marine engines, but requires adaptation. You will need to provide a specific mounting bracket for your engine and a suitable pulley, as this alternator is sold without a pulley.

Is the alternator protected against the marine environment?

Yes, this alternator is designed to withstand demanding marine conditions.

How to connect the alternator to the external regulator?

Connection is made via a dedicated cable harness. It is imperative to strictly follow the wiring diagram provided by Mastervolt during installation.

What is the advantage of a 150A alternator for a 24V system on a boat?

A 150A alternator in a 24V system delivers high power, enabling rapid charging of large-capacity battery banks. This reduces engine runtime required for charging and efficiently powers high-consumption onboard electrical systems.
