Solar Panel Installation

Custom design of a solar panel arch for two 400 W solar panels. The design included mounting point for tender davits, creating a multifunctional setup on the limited space of an IOR-style stern. The requirements of the design were a light weight structure which would not obstruct the cockpit, provide a space which minimizes shading of the panels and ease of manufacturing.

Yacht Electrification

For this project, a 70ft aluminium sailing ketch was re-powered from diesel to fully battery electric. First the original 800 kg Diesel engine was drained, disconnected and removed. This freed a large amount of space for the new 20 kg electric motor and some of the batteries.

A particular challenge on this vessel was the placement of the batteries, as no major modifications of the interior was desired, which called for creative placement of the battery modules. In all 32 7.2 kWh modules were installed for a combined capacity of over 230 kWh.

Custom Lithium Battery Install

For this project, a lithium battery was to be installed in an existing battery box while maximizing capacity, reliability and safety. The Battery was designed using individual prismatic LiFePO₄ cells to optimize the usage of the available space. Using these cells allowed the battery to take up 40% less volume as compared to off the shelf solutions, while fitting in to a pre-existing space. A state of the art Battery Monitoring System (BMS) and high quality ceramic automotive fuses ensure a high level of safety.

Compared to an off the shelf solution, the total system cost was 80% lower using individual cells. The BMS was also integrated to the ship’s network to allow remote state of charge and energy consumption/production monitoring. The 7.2 kWh battery bank along with 800 W of installed solar capacity means the vessel is essentially shore power independant, even for water heating and cooking loads.
