Crew installs blue power unit into aluminum catamaran hull
What this video covers
The crew of the aluminum catamaran Delos 2.0 installs and tests a shore power system designed to handle both 120V and 240V inputs while mitigating galvanic corrosion.16:50 The setup utilizes an auto-transformer to step up 120V to 240V and an isolation transformer to electrically decouple the boat from the dock’s ground, preventing stray currents from damaging the aluminum hull.17:09 Components are mounted on HDPE plates to further isolate electronics from the hull.18:33 The system includes a Vetus ignition-protected squirrel cage fan to ventilate the watertight electrical compartment, controlled by a thermostat.22:07 To verify the design, the crew uses a step-down transformer to simulate different international shore power voltages, confirming that the relays correctly route power through the transformers and that the Residual Current Circuit Breaker (RCCB) functions as intended.23:35 Additionally, the crew uses a 3D laser scanner to map the roof for custom-fit flexible solar panels from Open Water Solar.13:04
