Grand Banks Victron MultiPlus-II

Case Study: Victron Solution for Grand Banks 52 Yacht Electrical Issues and Inverter/Charger Repair by Dickerson Harbor Boatyard

Overview of the Project

The Dickerson Harbor Boatyard recently undertook a challenging project involving a Grand Banks 52 yacht that was experiencing electrical issues leading to premature failure of the old inverter/charger. The project aimed to identify and rectify the root cause of the problem, while ensuring the installation of a reliable and efficient replacement unit.

Challenges Faced

The primary challenge faced by the boatyard was troubleshooting the root cause of the electrical issues. The problem required extensive troubleshooting to recreate the problem and accurately diagnose the faults. The complexity of the yacht’s electrical system necessitated the expertise of experienced technicians at Dickerson Harbor Boatyard to identify the underlying issue. We found that there were numerous wiring problems from earlier modifications over many years. Multiple loads had been added to some breakers. Neutrals were not wired to a separate bus and the inverter was overloaded with all the newly added AC loads.

Products and Services Utilized

To address the electrical issues and provide a reliable solution, the Dickerson Harbor Boatyard did a complete inspection and overhaul of the basic parts of the AC electrical system to make sure breakers only supplied one load and all the neutrals were installed per code. Some wiring was also increased in size. As a replacement inverter, we opted to install a new Victron Multiplus-II Inverter/Charger and a battery management system consisting of a Victron Cerbo GX and a Victron GX Touch 50 for touch screen control, monitoring and Wi-Fi connectivity. Victron is renowned for their high-quality and innovative marine electrical products, making them an ideal choice for this project. The selected 3000VA Victron Inverter/Charger was specifically tailored to meet the requirements of the Grand Banks 52 yacht, ensuring optimal performance and compatibility with the existing electrical system. The batteries were two 8D Lifeline AGM batteries for long life and high deep cycle power. The Multiplus-II is the key in a Victron Energy Storage System which can also add in solar panels. It serves as a UPS as well and provided remote monitoring from anywhere in the world when combined with the Cerbo (GX).

Successful Outcomes Achieved

The installation of the new Victron Inverter/Charger proved to be a successful solution for the yacht’s electrical issues. After extensive troubleshooting and the subsequent installation, the yacht’s electrical system was restored to full functionality. The premature failure of the inverter/charger was effectively addressed, providing the owner with a reliable and efficient power supply for their vessel.

The customer expressed immense satisfaction during sea trials and subsequent use that the problem had been resolved. The successful outcome not only eliminated the frustration caused by the electrical issues but also provided peace of mind in knowing that the yacht’s electrical system was in optimal, safe condition.

In conclusion, the Dickerson Harbor Boatyard successfully tackled the electrical issues faced by the Grand Banks 52 yacht. Through extensive troubleshooting and the installation of a new Victron MultiPlus-II Inverter/Charger, the boatyard was able to rectify the problem and restore the yacht’s electrical system to full functionality. The efficient resolution of the issue left the customer delighted with the service provided by the boatyard and ensured the longevity and reliability of their yacht’s electrical system.
