ARCO Zeus 24V 7kW Alternator with Isolated Ground and High-Energy Regulator

Zeus 24V 7kW 3.15 Alternator with Isolated Ground (Common Rail) Zeus High-Energy Alternator Regulator

Zeus 24V 7kW 3.15 Alternator with Isolated Ground (Common Rail)

The ARCO Zeus 24V 7kW alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM and almost 6kW (218 Amps) at under 6,000 RPM. In real-world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio generates over 6kW!

The ARCO Zeus 24V 7kW alternator turns on for cruising or at mid to higher RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitors 24V alternators utilize a 12V rotor and field current, which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitors 24V alternators, having a direct impact on the alternators lifespan.

Zeus High-Energy Alternator Regulator

ARCOs Zeus is the only high-energy external alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you can access information on your system that you never had before. This information will enable you to regulate your system and optimize your battery charge and alternator output, resulting in a safer experience while protecting your energy system investment.

Zeus is the only alternator regulator that can read 2 shunts at a time (the battery shunt and alternator shunt). This feature enables Zeus to react to inputs from the battery current/temperature and alternator current/temperature.

Through the ARCO Zeus application, you are in good hands. Your data is automatically logged and can be shared with your technician to troubleshoot your system remotely. You can even import your remote technicians configurations.

Zeus optimizes battery charges for 12-48 volt systems. Whether you are using Lithium (LiFePo4) batteries or lead-acid Deep Cycle batteries, Zeus has you covered with its pre-set battery libraries and configurable menus to optimize your charging profiles. Zeus manages a complex set of inputs by giving you easy-to-understand options.

Zeus also takes into consideration the power of your engine and allows you to configure the alternators power take-off from the engine by managing the field, or duty. An advanced feature of Zeus is that it can turn your engine into a dedicated generator with the press of a button, whereby it focuses the alternators performance on the creation of energy to replenish your battery bank quickly.

Consistent with Zeus ease of use, Zeus is the only alternator regulator on the market that comes with alternator/battery harnesses and 2 thermistor harnesses, without an additional charge, saving users money and time from sourcing harnesses.

The ARCO Zeus 24V 7kW alternator is engineered for high energy production in demanding applications such as marine, RV, military, and commercial environments. Its innovative design features a native 24V rotor and field current, which deliver superior efficiency and cooler operation compared to traditional 12V rotor units. This results in increased durability and extended lifespan while providing substantial power output at cruising and higher RPMs. At just under 3,000 RPM, it generates over 3kW (109 amps), and at under 6,000 RPM, it pushes close to 6kW (218 amps), making it ideal for large battery banks and demanding power needs. Practical in real-world use, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio can produce over 3kW, while a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio can generate over 6kW. The alternator’s robust construction incorporates heat-shedding coatings, exterior-mounted rectifiers, and dual cooling fans to keep operating temperatures low, which enhances performance and reliability. Its large frame size and efficient design allow it to run cooler and more efficiently than older, heavier models, making it a reliable choice for continuous high-power applications. The alternator is compatible with Yanmar Common Rail engines introduced after 2013, including models such as JH-CR, 3JH40, and 4JH110. It features a high-performance external regulation system—the ARCO Zeus High-Energy Alternator Regulator—that offers Bluetooth connectivity through a native app for seamless configuration and monitoring. This regulator can read two shunts simultaneously, providing detailed insights into battery and alternator currents and temperatures, and supports remote data logging and troubleshooting. The Zeus regulator also supports a range of battery types, including lithium and lead-acid deep cycle batteries, with pre-set libraries and customizable profiles to optimize charging. Additional features include the ability to turn your engine into a dedicated generator with a simple button press, and comprehensive included harnesses and thermistors for easy installation.
