Zeus 24V 4kW Low Turn On (LTO) J180 4" Alternator with Isolated Ground

The ARCO Zeus 24V 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!

The ARCO Zeus 24V 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

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 competitors’ 24V alternators, having a direct impact on the alternator's lifespan.

Zeus High-Energy Alternator Regulator

ARCO’s 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 technician’s 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 alternator’s 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 alternator’s 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.

Features:

  • Secure Bluetooth connection
  • Harnesses, Thermistors, and NMEA 2000 kit included
  • Monitors the state of charge
  • Can turn your engine into a dedicated generator with generator mode
  • Pre-set battery libraries

Expensive but good
Flavor Name: Medium and Dark Roast Variety Pack, Size: 10 Count (Pack of 3)
I make my own pods for cost savings these are way too expensive but that said they are super good excellent quality coffee for sure but paying almost 50$ when I can make my own for 10$ is a no brainer but it does require some extra steps so do I recommend these absolutely I just prefer to make my own because I like Gevalia coffee far better

Great mix of Celsius flavors.
Flavor Name: Assorted Flavor Variety, Size: 12 Fl Oz (Pack of 12)
On average, I drink a Celsius a day. Most flavors are pretty good. I like the variability in this assortment. Hence the reason I have this set up on auto order ever few weeks.

Cola flavor is a NO
Flavor Name: Assorted Flavor Variety, Size: 12 Fl Oz (Pack of 12)
I am on a subscription for Celsius. The variety pack gets changed up every so often so it’s nice to try different flavors and exciting to see what I got in my latest shipments. For those bummed out because “Cola” was not included, don’t be. This is a throw away for me. Was hoping for a Diet Coke taste, but it’s not. It’s vile. All other flavors are great, tons of energy before the gym without jitters , low calorie, and I like the amount of carbonation, I think it’s perfect.
