Arco Starting & Charging 4501 Zeus 24V 7kW High Output Marine Alternator with Isolated Ground 3.15" J180 Mount

The Arco Zeus 24V 7kW alternator is engineered to deliver exceptional high-amperage output at cruising and elevated RPMs, making it ideal for marine, RV, military, and commercial applications requiring rapid charging of large battery banks.

High-Performance Output:

• Continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM
• Delivers nearly 6kW (218 Amps) at under 6,000 RPM
• Real-world performance: marine diesel engine at 1,500 RPM with 2:1 pulley ratio generates over 3kW
• Native 24V rotor and field current for superior efficiency compared to competitors using 12V components

Advanced Design Features:

• Isolated ground configuration for enhanced electrical system protection
• 3.15" J180 saddle-style mount replaces most small case styles (Hitachi, Lucas, Mitsubishi)
• Compatible with most Yanmar marine diesel engines
• E-Coat/Cerakote finish maintains cooler operating temperatures for sustained amperage output
• Runs cooler than traditional larger, heavier alternator designs
• Optimized for performance at idle speeds

Key Benefits:

• Reduces generator dependency by maximizing engine power conversion
• SAE J1171 Certified for quality and reliability
• Compatible with ARCO Zeus Bluetooth Alternator Regulator for lithium battery charging and advanced system monitoring
• Proudly manufactured in the U.S.A.

This high-output alternator provides the power needed to support modern electrical demands on marine vessels and commercial applications while maintaining cooler operating temperatures for extended service life.
