Zeus A8000-48V 8kW 3.15 Alternator with Isolated Ground

The ARCO Zeus A8000-48V alternator turns on at lower RPMs, runs cooler, and provides more power than other 48V alternators that are larger and heavier. This alternator continuously generates over 3kW (55 Amps) at 2,500 RPM and almost 6kW (111 Amps) at 4,000 RPM. Put in real-world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!

Instead of using rotors designed for 48 volts, many competitor alternators simply use their 12V rotors, which are less efficient and limit output at all RPMs. In this scenario, your external smart regulator must drastically reduce the field by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitors’ 48V 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
  • Data logging and sharing

Very firm pillow
Size: Queen (Mid Loft), Number of Items: 1
I'm not sure I received the same pillow as advertised. The pillows I received are extremely firm. I would not classify it as medium. It was also not covered by a cotton case. it had a very sheer gauze like material covering the latex.

Super springy and comfy!
Size: Queen (Mid Loft), Number of Items: 1, Size: Queen (Mid Loft), Number of Items: 1
I’ve been looking for a pillow that offers support but is soft and cushy. I had never tried a latex pillow before, and I was skeptical because I heard it could be hard, but I decided to give it a try. I tried a memory foam and it was waaaaay too hard to be comfortable. This pillow retains its shape, is really soft and plushy, and works great for back or side sleeping. It had a slight smell (not unpleasant though) when we first unboxed it, but it was gone by day 2. The pillow also sprang up immediately on unwrapping it. After a few days it seemed a little bit bigger, but it didn’t really need any time to air out/fluff up, it was basically ready straight out of the box. I’m often picky about pillows because I get headaches from sleeping on my neck in the wrong way, but this one is great and I haven’t had a problem at all. My hubby likes it too :) it’s the favorite house pillow now.

Sleeping like a dream!
Size: Queen
We stayed at a Westin hotel recently and usually I don't sleep well when traveling but this overnight stay was heaven! I don't know what magic is in these pillows but they are a dream! I sleep in my side and these are perfect, I sleep the entire night with no back or neck issues. I've tried some expensive pillows from Sealy, Serta, etc, and nothing compared to the Westins! So glad these are available through the Westin Amazon store! And less expensive than anything else I've tried.

Not the same as hotel pillows.
Size: King
Ordered this pillow after staying at a Westin hotel. I should have returned it because it seemed different from the pillow at the hotel. It feels worn out and doesn’t keep its shape. Would not recommend.

Big high pillow, firmer than expected.
Size: Queen
This pillow could be a 5 for some people , and it was a 1 for us. Too high for our neck. Side sleepers. It’s probably very good for a back sleeper.
