ARCO Zeus A7000 High Output Alternator – 24V – 7kW

The ARCO Zeus A7000 is the ultimate 24-volt power solution, delivering a massive 7kW of energy production for vessels with extreme electrical demands. Designed for yachts, commercial vessels, and off-grid RVs that require maximum charging capacity at cruising speeds, the A7000 is the premier “High Energy” choice for replenishing massive battery banks and powering heavy 24V loads.

Product Description

• 7kW High-Energy Performance: The Zeus A7000 is engineered for raw power. While it still delivers a respectable sustained idle output of 50A at 3000RPM while hot, its true potential is unleashed at cruising speeds. Capable of generating a sustained cruising output up around 220A when hot at 6000RPM, the A7000 provides the massive energy throughput required to run high-load systems—such as electric winches, large-scale climate control, and rapid Lithium bank replenishment—without the need for a secondary generator.
• Native 24V Architecture & Thermal Efficiency: Unlike “converted” 12V designs, the ARCO Zeus A7000 features a native 24V rotor and field current. This specialised architecture ensures higher efficiency and significantly cooler operation. By reducing internal heat, the A7000 minimises thermal derating and maximises the lifespan of its heavy-duty internal components. To further manage the intense heat, the unit is equipped with dual internal cooling fans, an exterior-mounted rectifier, and heat-shedding Cerakote or E-coat finishes.
• The Connected “Smart” System: The A7000 is designed strictly for external regulation and reaches its peak performance when paired with the ARCO Zeus Bluetooth Alternator Regulator. This pairing allows you to monitor and adjust your 24V system in real-time via the Zeus mobile app. With dedicated Lithium (LiFePO4) profiles and NMEA 2000 compatibility, the A7000 integrates seamlessly into your vessel’s digital backbone, providing total visibility of your energy production on any modern multi-function display (MFD).

Key Features

• Massive 7kW Output: Delivers up to 284 Amps (24V) of raw charging power.
• Native 24V Design: More efficient and runs significantly cooler than adapted 12V models.
• Superior Thermal Management: Dual fans and an exterior rectifier for continuous high-load operation.
• Bluetooth System Visibility: Real-time data monitoring and app-based adjustments (requires Zeus regulator).
• Optimized for Lithium: Advanced algorithms protect and rapidly charge high-capacity Lithium banks.
