This winters BIG project on Sailing MacMac was to construct and install a solar arch, upgrade the batteries to Lithium and install a more powerful inverter and a user friendly Battery Management System.

The project was started in November when we started purchasing all the bits and pieces as well as designing and arranging for the solar arch to be fabricated in Port Ginesta
