This alternator continuously generates over 3kW (55 Amps) at 2,500 RPM and almost 6kW (111 Amps) at 4,000 Alternator RPM. Put in real-world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!\u003c\/p\u003e\u003cp\u003eInstead of using rotors designed for 48 volts, many competitor alternators simply use their 12V rotors which is less efficient and limits output at all RPMs. In this scenario, your external smart regulator must drastically reduce field, by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitors 48V alternators, having a direct impact on the alternators lifespan.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEngineered for high energy production.\u003c\/li\u003e\n\u003cli\u003eSuitable for marine, RV, military, and commercial applications.\u003c\/li\u003e\n\u003cli\u003eRapidly charges large battery banks.\u003c\/li\u003e\n\u003cli\u003eCoolest operating temperatures for increased performance:\u003c\/li\u003e\n\u003cli\u003eHeat shedding coatings\u003c\/li\u003e\n\u003cli\u003eRectifier located on housing exterior\u003c\/li\u003e\n\u003cli\u003eDual cooling fans\u003c\/li\u003e\n\u003cli\u003eOEM components\u003c\/li\u003e\n\u003cli\u003eOptimized for performance at idle speeds.\u003c\/li\u003e\n\u003cli\u003eReduces the need for a generator by creating additional power with your engine.\u003c\/li\u003e\n\u003cli\u003eUnleash peak performance with E-Coat\/Cerakote, keeping the high amp alternator cooler for sustained amperage output.\u003c\/li\u003e\n\u003cli\u003eUse the ARCO Zeus Bluetooth Alternator Regulator for maximum performance or lithium battery charging.\u003c\/li\u003e\n\u003cli\u003eSAE J1171 Certified.\u003c\/li\u003e\n\u003cli\u003eProudly made in the U.S.A.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eVoltage - 48v\u003c\/li\u003e\n\u003cli\u003eField Type - P\u003c\/li\u003e\n\u003cli\u003eRotor Poles - 16\u003c\/li\u003e\n\u003cli\u003eStator Size - 138mm\u003c\/li\u003e\n\u003cli\u003eFrame Size - Large\u003c\/li\u003e\n\u003cli\u003eWeight - 15.89lbs\/7.2kg\u003c\/li\u003e\n\u003cli\u003eRegulation - External Only\u003c\/li\u003e\n\u003cli\u003eFinish - (Black) E-coating\u003c\/li\u003e\n\u003cli\u003eCut-In RPM - 1,920 Alternator RPM\u003c\/li\u003e\n\u003cli\u003eMaximum Alt RPM - 19,000\u003c\/li\u003e\n\u003cli\u003eBattery Post - M8 Thread Post, Side Mount\u003c\/li\u003e\n\u003cli\u003eStandard Pulley - 49K6 (6-groove, 49mm)\u003c\/li\u003e\n\u003cli\u003ePulley Mount - 17mm diameter shaft, 25mm long, threaded M17 x 1.5\u003c\/li\u003e\n\u003cli\u003ePulley Hardware - M17 x 1.5 x 24mm nut, w\/ 18mm ID x 29mm OD washer (Included)\u003c\/li\u003e\n\u003cli\u003eDiodes - 6 positive, 6 negative, 80A Rated, Avalanche\u003c\/li\u003e\n\u003cli\u003eMax Output (Cold, 9,000 RPM) at 53.5v - 180 Amps - 9,360 Watts  14.8 kW PTO\u003c\/li\u003e\n\u003cli\u003eSustained Cruising Output (Hot, 6,000 RPM) at 53.5v - 138 Amps - 7,383 Watts  10.5 kW PTO\u003c\/li\u003e\n\u003cli\u003eSustained Idle Output (Hot, 2,500 RPM) at 53.5v - 78 Amps 4,173 Watts  6kW PTO\u003c\/li\u003e\n\u003cli\u003eMax Continuous Operating Temperature - 100C \/ 212F\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eMounting Application:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eMust Be Used on Yanmar Common Rail Engines Introduced after 2013 (JH-CR, 3JH40, 4JH45, 4JH57, 4JH80, 4JH110).\u003c\/li\u003e\u003c\/ul\u003e \u003c!--- cis2:m2lumZRk ---\u003e\n\u003cp\u003eThe ARCO Marine Zeus A8000-48V alternator is designed for high-performance energy generation in marine, RV, military, and commercial applications. It delivers over 3kW (55 Amps) at just 2,500 RPM and nearly 6kW (111 Amps) at 4,000 RPM, providing reliable power for large battery banks and reducing the need for a separate generator. Its advanced design ensures efficient operation at lower RPMs, resulting in cooler running temperatures and extended component lifespan. The alternator features a native 48V rotor and field current, optimizing performance without the inefficiencies common in competitors that use 12V rotors, which can lead to system damage if not properly regulated. The heat-shedding coatings, exterior rectifier placement, and dual cooling fans contribute to its superior thermal management, enabling sustained high amperage output even during extended operation. Designed for easy integration, the ARCO Zeus A8000-48V includes standard components such as a 49mm multi-groove pulley, M8 side mount battery post, and avalanche-rated diodes. It is SAE J1171 certified and proudly manufactured in the USA, ensuring quality and durability. This alternator is particularly suitable for use on Yanmar common rail engines introduced after 2013, including models like JH-CR, 3JH40, 4JH45, 4JH57, 4JH80, and 4JH110, making it an ideal upgrade for demanding power systems. The optional Bluetooth regulator and compatibility with lithium batteries further enhance its versatility, allowing users to maximize performance and battery efficiency in various operational environments.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eEngineered for high energy production and reliable performance across marine, RV, military, and commercial applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRapidly charges large battery banks with sustained high amperage output\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOperates cooler than competitors due to heat-shedding coatings, exterior rectifier, and dual cooling fans\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNative 48V rotor and field current for increased efficiency and longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes OEM components such as multi-groove pulley, M8 side mount post, and avalanche-rated diodes\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptimized for performance at idle speeds with advanced thermal management features\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReduces reliance on external generators by generating additional power directly from engine RPM\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eE-Coat\/Cerakote finish keeps the alternator cooler for prolonged high-performance operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with ARCO Bluetooth Alternator Regulator for maximum control and lithium battery charging\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSAE J1171 certified for quality assurance and durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProudly made in the USA to ensure high manufacturing standards\u003c\/li\u003e\u003c\/ul\u003e","brand":"ARCO Marine","offers":[{"title":"Default Title","offer_id":44528531931178,"sku":"108030","price":2143.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/108030XL.jpg?v=1783037646","url":"https:\/\/atticusgoods.com\/products\/arco-marine-zeus-a8000-48v-8kw-alternator-with-isolated-ground-for-common-rail-engines","provider":"Atticus Goods","version":"1.0","type":"link"}
