Revatek is growing quickly and building a dealer network. We suggest you or your preferred technician buy direct from our website. Our team would love to connect with them if they would like to speak with us about technical details or building a wholesale relationship. The Altion is typically easier to set up than other alternator regulators.

Replacing existing alternator regulators is straightforward for those with electrical experience. For new and/or complex installations, we recommend enlisting the help of a skilled technician for the installation process. For marine applications, we recommend seeking out an ABYC-certified technician, as they typically have extensive training in system installation.

Out of the box, the Altion creates a Wi-Fi network on startup. Connect to that network with your phone, tablet or computer and input your configuration. Many techs can finish in less than five minutes. It's that easy.

The Max has an OLED screen on the enclosure to convey charging information. It is also designed to regulate two alternators and supports one or two battery banks, which is ideal for boats with two engines. This is simpler and more cost effective than alternative solutions.

The Altion operates anywhere between 12 – 60 volts. It easily accommodates 12, 24 and 48 volt systems, plus anything in between.

The Altion is compatible with virtually all marine and automotive batteries with nominal voltages from 12 – 48 volts. This includes both lead acid (e.g., flooded, AGM) and lithium (e.g., LiFePO4). For lithium in particular it is critical to configure the Altion to charge within the specifications of the battery manufacturer to avoid self-disconnects by the internal battery management system. Battery disconnect protection, such as avalanche diodes within the alternator and/or an external alternator protection device, is highly recommended. We do not certify specific batteries and are not responsible for any issues related to battery disconnects.

The difference between the two types is the direction of the current flow through the field coil in the alternator. The Altion wiring harness is shipped from the factory for P type, and can be easily reconfigured by the installer for N type. Most externally regulated alternators in the US and in the global marine market are P type. N type is prevalent in automotive and European setups. It’s important to configure properly for your type, as improper wiring will cause damage.

Yes, provided the alternator is modified to enable external regulation. If you pursue this modification, we recommend using a skilled alternator technician. With that said, engine factory alternators are typically underpowered for house loads, and we often recommend using a high-quality aftermarket alternator, either to replace or supplement the factory alternator. Ensure that the original alternator is not connected to the engine computer if replacing the factory alternator.

The necessity of a secondary alternator largely depends on its application. For most automotive uses, such as in RVs and trucks, the alternator is an integral part of the engine’s computer control. Typically, the primary alternator communicates with the engine computer, and such systems don’t allow external regulators like the Altion. In these instances, it’s necessary to add the Altion to a secondary alternator dedicated to managing house battery loads. On the marine side, this same holds true for some newer engines, though often primary alternators are not connected to the engine computer, making them suitable for the Altion.

The alternator’s capacity depends on the size and type of the battery bank being charged. Ideally alternators should be sized to charge as fast as the batteries can handle within their factory recommended charge parameters. Check your battery specifications for precise recommendations. For typical lead-acid batteries, the alternator should output 25% of battery bank amp hour capacity. For typical lithium batteries, the alternator should output 50% of battery bank amp hour capacity. Add another 10% to these figures to account for the notion that most alternators do not achieve their rated output in real-world conditions. The Altion precisely controls the alternator’s output and temperature, ensuring its longevity while charging batteries as quickly as possible.

The Altion measures current to precisely determine a battery’s state of charge. This is crucial for newer technologies like LiFePO4 where voltage alone isn’t a reliable indicator. Unlike most other systems, Altion adjusts alternator output based on current measurement to keep the battery at 100% charge and prevent overcharging. This method allows the Altion to charge faster, more accurately and with greater safety. It also extends the lives of the batteries and alternators by keeping them precisely within their design parameters.

The Altion is compatible with most analog shunts from 25-160 mv. However, some smart shunts may not be compatible. If your shunt has accessible small machine screws on the side of its resistive blocks, it should work with the Altion. If there are no accessible small screws, it will not work. Do not connect the shunt wires to the posts that the main cables connect to as that could provide errant readings and damage the Altion. The amp rating of your shunt should exceed the maximum load you expect on your battery bank.

The shunt should be the only thing connected to the battery bank negative terminal. Everything other negative cable should be connected through the opposite end of the shunt. This approach allows the shunt to measure all battery current.

Yes. We recommend using 16 AWG wire if needed. Extensions of 15 feet or less are typically acceptable. If extending the shunt current sense wires, twist them together to retain maximum accuracy.

Some batteries, e.g., lithium, can self-disconnect from their charging source for safety and to prevent overcharging. For any such battery, the alternator and other electronics must be protected from a battery disconnect while the alternator is charging. While the Altion responds to such events by stopping charging within milliseconds of detecting a disconnect, alternators will continue charging for a short period after shut off due to electromagnetic induction. We strongly suggest using an alternator fitted with avalanche diodes. These diodes are specifically designed to endure and neutralize voltage spikes caused by sudden disconnects. Additional protective devices, designed to enhance the alternator’s capacity to handle voltage spikes, while not strictly necessary when the alternator has avalanche diodes, provide additional protection.

Yes, simply configure the field voltage to 12 volts in setup.

Yes. The Altion Max can independently regulate one or two alternator groups on one or two battery banks. An alternator group refers to matched alternators attached to the same engine, as long as maximum field current across an alternator group is less than 16 amps.

A flashing light indicates a fault condition. Ensure that the Altion's Wi-Fi is on and connect to it with your phone, tablet or PC. The dashboard will display the fault.
