Douglas cited bigger engines, larger battery banks, generous electrical panels, increased tankage, and all-teak interiors in a package that s better built, more comfortable, and performs better as examples of what Catalina is trying to achieve.
39.
Power from the generators is channeled through a Xantrex inverter, which sends the power either to the battery banks to recharge them or via a panel with 19 circuit breakers, to the HAB electrical distribution system.
40.
In 2007 the system was extended to include a battery bank charged by two photovoltaic solar arrays, and by a 6 kW wind turbine sited at a redundant telecommunications tower on the high point of the island.
