ARCO Zeus High Energy Alternator Regulator
ARCO’s Zeus is the only high-energy alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you have access to information on your system that you never had before. This information allows 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 measures and reacts to inputs from the Battery current and temperature and the Alternator current and temperature.
Through the ARCO Zeus application, you are in good hands as your data is automatically logged and can be shared with your technician to troubleshoot your system when remote. 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 to 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 a press of the button, whereby it focuses the alternator’s performance to the creation of energy in replenishing your battery bank quickly.
Consistent with Zeus’s 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.

ARCO Zeus App
ARCO Zeus Installation Guide
Yes, ARCO Zeus is compatible and integrations with Victron systems.
The installation is simple. Once your wiring is complete, download the ARCO Zeus app, connect to Zeus via secure Bluetooth and finish the installation process without wires or other tools.
Yes, Zeus is agnostic when it comes to which alternator it will work with.
You will need information on your battery and your alternator. Most batteries have all of the information you need on their label. For the required alternator information, you may need to visit the manufacturer’s website, contact the manufacturer or your technician.
When charging there will be voltage loss/drop on the positive and negative wires between the alternator and the battery. Zeus features positive & negative volt sensing leads, something stock alternators do not have. These wires directly monitor battery voltage, at the battery terminals, so the regulator can compensate for the voltage drop in the output wiring. Volt sensing is a critical component of Zeus.
ARCO Zeus has an alternator temp sensor that will modify the field current to let the alternator cool and keep it to a safe temp. Charging at idle can generate a lot of heat in factory alternators because the alternator is cooled by a fan and at low RPM you have low air flow.
ARCO Zeus can be fully custom programmed, via an easy to use app on your phone and set to whatever voltage and duration you need.
You calculate your pulley ratio by dividing the diameter of your crankshaft pulley by the diameter of the alternator pulley. For example, A 4”-inch crank pulley with a 2 inch alternator pulley will yield a 2:1 pulley ratio. (4 divided by 2 = 2:1) This means that the alternator will be spinning 2 times the engine RPM. In other words at 2000 engine RPM your alternator will be spinning at 4000 RPM.
ARCO Zeus can be fully custom programmed for your specific batteries.
Absolutely, and every parameter from max alt temp to absorption voltage, float voltage and the duration of each stage is fully programmable to your needs.
