What this video covers
Managing electrical loads on an off-grid boat requires prioritising energy production over storage capacity and shifting high-draw tasks to peak solar hours. A 600-amp-hour battery bank supports two people, but solar arrays should be maximised to prevent chronic under-production.2:23 Heating water with electricity consumes roughly 50 amp hours in 15 minutes; using engine heat via a cooling loop or timing electric heating to coincide with peak solar output preserves battery reserves.2:19 Propane stoves eliminate the electrical cost of boiling water or cooking.1:56 Air conditioning creates unsustainable loads, making passive ventilation—using wind scoops and strategic hatch placement—the preferred method for cooling.5:23 Phantom loads from inverters and routers drain batteries continuously; hard switches and prioritising DC-powered appliances reduce these losses.6:02 Refrigeration remains the largest continuous load, requiring careful insulation and organisation.6:50 Starlink internet systems also impact energy budgets, with the standard dish drawing over 5 amps continuously, while the Starlink Mini offers a more efficient 12-volt alternative.7:43 Success in off-grid living depends on intentional energy consumption and scheduling heavy tasks during daylight.
