Taia is energy self-sufficient with renewable sources. As a backup to power generation, she has a 100-Amp alternator and a 5.5 KW diesel generator.
The family of four that lived aboard used roughly 200 Amp-Hours a day, including making around 20 gallons of water a day with the 12-volt water maker, and two 12-volt refrigeration compressors (one for the refrigerator, another one for the freezer). The solar panels and wind generator are perfectly capable of producing more than 200 Amp-Hours a day. And for those rare stints of no sun and no wind, the generator can easily charge the batteries.
All the lights aboard Taia are LED's, including all cabin lights, navigation lights and anchor light. We have a photosensitive anchor light on the arch that consumes about 0.3 Amps. It turns on at dusk and stays on till dawn.
- House bank: 8 Deka ProMaster GC25 6-volt batteries totaling 920 Amp-Hour capacity. New in November/2014.
- Solar panels: Two 270-Watt, 24-volt panels controlled by a Morningstar Tristar MPPT 45 controller. The panels bear the brunt of the generation. New in December/2013.
- Wind generator: Silentwind 400 W, with its own controller. New in August/2015.
- Generator: Next Generation Power 5.5 Kilowatt diesel generator powered by Kubota engine. The generator is installed in the engine room and is started/stopped from a button on the 110-volt electrical panel. The generator has its own hour counter, which marks 1346 hours.
- Alternator: 100-Amp alternator.
- Charger/inverter: StatPower ProSine 3.0 with Advanced Control System panel. 3000-Watt inverter.
- Shore power: Two 30-Amp connectors and cables.
- Battery monitor: Link10 monitor that keeps track of production/consumption of Amp-Hours, as well as battery voltage and current.
