What this video covers
The crew of the expedition catamaran Zatarra manages offshore power and water independence using a redundant system of solar, generators, and desalinization.▶ 1:22 The electrical system centers on an 1,800 amp-hour, 24-volt lithium-ion battery bank monitored by a Victron CERBO GX70 display and Victron distribution components.▶ 2:09 Solar capacity includes ten 330-watt panels, each equipped with an independent solar charge controller to mitigate shading losses, producing 2,500 to 2,800 watts at peak.▶ 4:41 Two diesel generators—a 14kW primary and a 9kW backup—provide additional power, supplemented by accessory alternators on the main engines.▶ 1:48 The vessel utilizes a 60-gallon-per-hour water maker, which requires 750 to 850 psi to process seawater through membranes.▶ 10:04 Maintenance involves regular replacement of pre-filters and the addition of calcium carbonate to the output for mineral balance.▶ 12:01 High-consumption appliances include air conditioning, a dishwasher, and a washing machine, which uses 10 gallons of cold water per cycle.▶ 3:06 The crew emphasizes the necessity of thermal scanning electrical connections to prevent fires caused by loose, overheating terminal blocks.▶ 7:21
