Zeus 24V 7kW 3.15 Alternator with Isolated Ground
The ARCO Zeus 24v 7kW alternator is a powerhouse, generating extremely high amperage when cruising or at higher RPMs. At just under 3,000 alternator RPM, it continuously pumps out over 3kW (109 Amps), and at under 6,000 RPM, it almost hits 6kW (218 Amps). In practical terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio can generate over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio can generate over 6kW!
This alternator kicks in during cruising or at mid to higher RPMs. It runs cooler and provides more power than older, bulkier designs. The latest generation of 24V performance is here.
Competitors' 24V alternators use a 12V rotor and field current, which is less efficient and limits output at all RPMs. ARCO uses a native 24V rotor and field current, making our 24V alternator run cooler and last longer.

Using the ARCO Zeus 24V 7kW alternator is easy. First, make sure it's properly mounted according to the mounting application details provided. It can replace most small - case alternators with a 3.15” J180 saddle style mount. When your engine is running, the alternator will start working at around 1,962 alternator RPM. You can use it for various applications like in marine vessels, RVs, military equipment, and commercial vehicles. For maximum performance, especially when charging lithium batteries, use the ARCO Zeus Bluetooth Alternator Regulator. As for maintenance, keep an eye on the operating temperature. The alternator has features like heat - shedding coatings, a rectifier on the housing exterior, and dual cooling fans to keep it cool, but it's best not to let it exceed 100°C / 212°F. Also, check the battery post and pulley hardware regularly to ensure they are in good condition. Since it's made in the USA with OEM components, you can expect reliable performance, but following these simple steps will help it last even longer.
