Scotty AI is a bi-directional DC DC 12V to 48V and 24V to 48V that uses AI for auto-tuning. It is supported by a smartphone app and has over the air updates.

This is the second version of Scotty called Scotty AI

Introducing Scotty AI: A Revolutionary Power Converter

Scotty AI is a cutting-edge bi-directional DC DC power converter, equipped with an AI-driven controller that redefines power management in marine applications.

  • Intelligent Power Extraction: Automatically draws power from an alternator, with AI auto-tuning to match the specific alternator attached.
  • No need for engine RPM measurement to optimize its output.
  • Three Power extraction settings at idle: "Soft", "Medium", "Hard" easily changeable on the Touch Display on the helm.
  • Reverse Power Direction: When the engine is off, Scotty AI reverses power direction for optimal efficiency.

Scotty AI's unique AI functionality, protected by an international provisional patent, uses machine learning and mathematical modelling to form a dynamic power curve without the need for RPM measurement. This ensures efficient power output automatically allowing for alternator temperature and additional electrical loads at alternator voltage.

Scotty Ai vs 48V Alternator
SCOTTY AI REFIT ON PRIVELEGE Catamaran for Silent night on water


Privilege 51.5 owners wanted Silent Nights on the water. They also wanted to run “Zero Genset” and installed 3.2kW solar. The 12V DC loads are around 600W+ without winches/windless. A 48V 20kWh Lithium bank was installed as an energy overlay.

As a backup to solar two Scotty AI’s provide both a high replenishment capability and redundancy. When Scotty’s are off, the 12V alternators will continue to charge the existing 12V house battery.

With significant 12V loads, the available power to Scotty AI varies widely. Scotty AI’s patent pending auto-tuning maximizes the charging power prioritizing the 12V loads.

Should one alternator fail for some reason, the Scotty AI associated ceases operation automatically and the floating master role switches if required

The Smart Touch Display allows the skipper to set the alternator engine load to Soft, Medium or Hard depending whether motor sailing or solar back up power without running the Genset.

Scotty AI in NEW Lagoon 460 catamaran as power Overlay


For new-built catamarans in the 36-46ft size, the factory fitted 12V lithium house battery bank stays as installed and Scotty AI and a large capacity additional house bank at either 24V or 48V is an overlay energy system.

When running the engines, Scotty AI is auto-tuned with the “lithium house” enabled. The patent-pending auto-tuning is done on either engine independently. Scotty AI is then ready to run.

With either or both engines running, Scotty Ai waits till the house battery is significantly charged at 90%+  before cutting in and extracting power up to 3000W per engine. (the factory fitted engines on popular brands have 120A capacity at 14.4V and the 1500W Scotty AI model is a perfect fit)

When the engines are off, Scotty AI delivers DC power back to the factory fitted 12V house bank to keep it always in the circa 90% band.

Fishing Boat with Scotty AI bi-directional DC DC to 36V


Fishing boats with GPS-guided propulsion/autopilot packages and/or virtual anchor systems using high torque 36V motors have two options that significantly simplify a single house battery bank design:

    1. Scotty AI can simply provide the 24V or 36V load (generally up to 1500W is sufficient) on demand without the need for a 36V house battery. This can be from a single 12v house battery design.
    2. Scotty AI can simply charge a 24v or 36V Auxiliary battery and use the bi-directional feature to supply the 12V loads without the need for a 12V house battery.
    3. High loads, including up to a 3000W inverter can be used on the 12V side pulling power through Scotty AI from the 36V Auxiliary battery.
    4. The result is a simplified single auxiliary battery system.


For outboard engines, the features above allow the engine to idle with little or no net output, then ramp up the power to a full 3000W at cruising RPM (provided the outboards have alternator capacity). This unique and innovative product allows fishing boats to run gyro’s and other high demanding loads with a battery bank being charged at the same time the gyro is running.

  • The vessel can leave the dock immediately if the gyro application is for a “restful night” at anchor later in the day.
  • Scotty AI allows the gyro power demand to have priority at any engine RPM
  • Once the gyro demand has reduced after spin up, Scotty AI will extract power for the auxiliary battery if required.
  • Once at anchor, Scotty AI will direct power from the auxiliary battery bank back to the gyro as it is fully bi-directional DC DC.
  • Scotty AI can direct up to 3,000W to the gyro and any other 12V (or 24V) loads.

Sunseeker 80Ft with 24V Scotty Running Silent Night


Scotty AI provides both a high replenishment capability with redundancy with 24V alternators at 150A each. Up to two of these per engine have been fitted giving 16kw capacity. Two Scotty AI’s per engine can charge at 12kW.

An 48V Lithium bank is installed as an energy overlay. The existing 24V AGM house bank is preserved.

Scotty AI is auto-tuned per alternator. When all Scotty AI units are activated a patent pending ‘floating master” is established between.

Should one alternator fail for some reason, the Scotty AI associated ceases operation automatically and the floating master role switches if required

If the Scotty AI’s are charging the 48V auxiliary battery and this operation is stopped, the vessel can continue to run on the 24V AGM house bank.

Installed systems include a 100kWh 48V house bank being replenished from 12kW Scotty AI array which is sufficient to run the saloon and helm aircon loads and electronics power while motoring NO Genset. “Silent Nights”

Scotty AI is alternator charging using a revolutionary DC DC. It is "Automotive Grade" placing the reliability and ruggedness above commercial grade "Victron" products. 
Now in version 2, we have added AI. This is the result of over 300 installs of "manual tuning" in a wide variety of marine and RV applications. This is so revolutionary as it does not require the vehicle RPM to determine the alternator output. It determines it through AI which is patent pending.

  • Auto-tunes to the power curve of the alternator. It does this an a mandatory 2 minute startup process the first time you use Scotty AI. After that, it is auto-tuned.  
  • When the alternator temperature rises or other loads are applied at the vehicle, Scotty adjusts the tuning automatically for this alternator.
  • Layered on top of this are three "idle settings" as well as "off". Soft, Medium and Hard have 3 different power demand results on the alternator both at idle and when driving.
  • It shows the cable losses in watts for the alternator to Scotty AI cable and Scotty AI to Lithium battery with CAN BMS.
  • The firmware can be updated "OTA" Over-the-Air from your smartphone, tablet or laptop.

Meet Michael Nielsen. Michael upgraded from a Scotty Ver 1 to Scotty AI for his LC79. There is not much we can add to Michael’s testimonial so we will let you list to it first hand. 

Scotty gives simplicity as there is no need for a 12V house or auxilliary battery. It is 100% bi-directional. 

Scotty looks after your alternator with a dedicated alternator temperature sensor. There are 3 power settings at "idle". "Soft", "Medium" or "Hard".
