A7000-24v High output alternator
Description
If Optimal Charging at Fast Idle or at Higher RPMs Is Important to You, this is the Perfect Alternator for You
High Output / High Amperage Alternator: The Highest Power Output in Its Class
Note: If low speed charging is important to you, view our ARCO Zeus A4000-24V Low Turn On (LTO) Alternator here.
24V 7kW Advantage
The ARCO Zeus A7000-24V 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. To put in real world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio is generating over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio is generating over 6kW!
Best-in-Class Performance
The ARCO Zeus A7000-24V 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.
True 24V Alternators
Competitor’s 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 competitor’s 24V alternators, having a direct impact on alternator lifespan.
ARCO Zeus 24V High Amperage Alternators, A4000-24V LTO or A7000-24D: Which One’s Right for You?
Choose A7000-24V if:
- You primarily charge at cruising rpm or on the road
- You only charge every other day when moving to a new
location
- You are willing to trade low RPM output for class-leading output at
mid to high RPMs
*On the power curve graph, select A4000-24V LTO for use cases left of the Decision Point; otherwise, select A7000-24D.
If these do not apply to you, check out the A4000-24V LTO page here.
- Replace your noisy generator!
- Engineered for high energy production.
- Suitable for marine, RV, military, and commercial applications.
- Rapidly charges large battery banks.

Regulation
External Only (EX): These units will come with a terminal block and a P-Type harness. They will only work with an external regulator, such as an ARCO Zeus Bluetooth alternator regulator.
Transparency – How We Test For Output
To measure sustained output, the alternator is run at 3,000 RPMs for 60 minutes with a plexiglass shield covering the units. Testing shows that after 60 minutes in these conditions, alternators reach their maximum operating temperature, or the conditions under which the unit will produce the least output.
It is under these harsh conditions where we measure the “hot” output of the units at various RPMs. The complete power curve is shown above.
Note: The “hot” conditions are much less favorable than the conditions typically used in the industry. The temperature of the stator during our “hot” test was 305 °F. Incumbents measure the power curve at an ambient temperature of 140 °F. “Cold” testing was done at 71° F.
