Enjoy the SHP Shore Power Converter built with state-of-the-art technologies using a power core designed to achieve the best robustness and endurance in the market, and including advanced digital control techniques.
The SHP Shore Power Converter provides a permanent 3-phase supply to the yacht switchboard, converting the power provided by the shore worldwide with high reliability, robustness and precision.
The SHP converter features a 50 Hz transformer, allowing for bypassing the converter when the shore ratings are compatible with the onboard electrical system, thereby extending the equipment’s lifespan.
As an option, the power electronics can be reconfigured to provide a DC input from a battery and provide a silent mode to the yacht.
> OPTIONS: Seamless transfer, bypass mode, dual cord and silent mode.
The SHP Shore Power Converter offers a dual, seamless transfer to reach bypass mode, which disables the converter electronics, allowing the ship to be fed directly from the shore cord through the 50 Hz transformer.
Thanks to this mode, the power electronics are only used when there is an actual need to drift the frequency or the voltage from the shore to the ship.
After the seamless transfer from the genset to the converter, the control system compares the shore voltage/frequency with that on the ship. If a match is found, it performs a second seamless transfer from the converter to the shore, bypassing the power electronics.
This mode can be used in most of the ports around Europe.
The converter offers, as an option, the so-called silent mode, specially designed for when the ship is anchored. With this mode, the ship is powered by an onboard battery bank for a certain period, allowing the gensets to be turned off.
With this functionality, passengers can enjoy swimming and other recreational activities on the deck, surrounded by the sea and nature, with no noise, vibrations, or oil smells.
Once the ship resumes sailing, the converter will transfer power to the gensets and restore the energy used during silent mode.
SHP-X is an onboard shore power converter. It takes the low-voltage supply from the port, provides galvanic isolation and converts voltage and frequency to the yacht’s internal grid, so the generators can be switched off at berth.
Most units isolate the yacht with a high-frequency inverter, transformer and rectifier stage, which limits reliability and life cycle. SHP-X uses a simpler back-to-back converter, a rectifier and an inverter, with a low-frequency isolation transformer.
When the port supply already matches the yacht’s voltage and frequency, which is the usual case in Europe, SHP-X bypasses the power electronics and stops them. The converter only works when it is needed, which extends its life.
With an optional battery, the yacht can also switch off its generators at anchor for a period of time: no noise and no exhaust fumes while guests are on board.
The first prototype is rated 75 kVA and has been operating on board the yacht Petrus (Sanlorenzo SL108, 32.9 m) since March 2026 without incidents. The modular version combines 10 kW modules in parallel, typically seven or eight per unit, and is being developed for ratings of up to around 150 kW.
Yes. The modular version is designed for refits: modules fit through narrow hatches, the transformer is a separate block that can be placed where the engine room allows, the enclosure is stainless steel and cooling is simplified. A liquid-cooled transformer reduces size and weight.
SHP-X is installed on board and belongs to the yacht owner. The marina only provides the shore connection, so small ports do not need to invest in frequency converters.
Yes. SHP-X is designed to manage the port supply, batteries, solar panels and generators from one central converter.
