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

Perfect for precise and stylish measuring
Color: Bright Silver, Size: 4.1 Ounces, Color: Bright Silver, Size: 4.1 Ounces
This small stainless steel measuring cup exceeded my expectations. The material feels sturdy, high-quality, and has a sleek finish. It's also lightweight yet sturdy, making it comfortable to use. The tapered shape and front spout make pouring liquids easy and spill-free, and the wooden handle adds a beautiful and sophisticated touch. Plus, it stays cool to the touch when used with hot liquids. It's ideal for measuring coffee, cooking ingredients, or cocktails. Very practical, easy to clean, and doesn't retain odors. In short: a simple yet beautifully designed utensil, useful for everyday use, and of excellent quality. I highly recommend it!

Perfect Little Espresso Cup
Color: Bright Silver, Size: 4.1 Ounces
I’m really impressed with these 4oz espresso cups. The bright silver finish looks premium, and the wooden handle feels sturdy and comfortable to hold—no worries about heat transfer. The double spouts make it super easy to pour shots cleanly into two cups or split a double shot without mess. The size is perfect for single or double shots, and it doubles nicely as a small measuring cup for my coffee bar setup. It feels durable and well-made, and it definitely adds a bit of flair to my espresso routine. Overall, great quality for the price. Highly recommend for home baristas!

Handle Came Off

Excellent for pulling espresso shots, looked great, no rusting... until the welded handle just popped off after a few months with hand washing only.
