Jeanneau NC 33 with integrated 462Wp Solbianflex SP custom solar system. Three synchronized MPP trackers and 12 bypass diodes ensure optimum performance even when partly shaded or obstructed by the sliding roof.
One of the main challenges of this project was the sliding roof which covers parts of the solar system when opened. To minimize the effects of this obstruction, the system has been split into three independent strings. In addition, bypass diodes have been integrated in these strings, bridging parts as they get shaded or covered so the rest of the panel keeps on working.
The three strings are controlled by Victron SmartSolar MPPT charge controllers, which are synchronized using a smart bluetooth network. A wireless voltage and temperature sensor on the service battery optimizes the charge voltage to ensure the batteries are always receiving a perfect charge.
All wiring of this fully walkable system is fed through the roof directly below the panels. This not only makes the wires invisible from the outside, it also gives protection from the elements and neatly integrates the panels into the design of the yacht.
