What's Your Electrical set-up?

15m sailboat

24volt system
4x6volt 460ah deep cycle (could do with more)
2x110ah engine
70amp service alternator with booster
35amp engine alternator
2x78w solar panels (definitely need more)
Wind generator (none and hope to stay that way)
6.5kva Onan generator

Toys!

2 x water cooled fridges with ice boxes ( only one on when anchored or sailing)
Victron 24v/3000w/70a charger/inverter, Fluorescents (7w each) and led lighting. TV/DVD. Radio/CD/USB. Laptop. Fans, stand alone A/C (never used). Full Autohelm ST7000 nav pack. Radar. Navtex, VHF. 2 x GPS/Plotters. 24v watermaker. Washing machine/Dryer, 3 x water pumps. 3 x discharge pumps. 1500w windlass. 10kw bow thruster

Rarely use shore power, if we have not done any motoring through the day, generator top up generally required, (around 1-1.5 hours run depending on toys used).
 
My set-up:
12.7m yacht based in Sicily
600 AH domestic bank (2x 200 AH lead acid truck batteries)
160 watt solar on aft gantry
Rutland 913 wind genny
Engine charge about once a week maximum if needed
60 amp alternator on engine with Sterling smart regulator

Consumption Notes: Med, air-cooled fridge, LEDS for all longer duration lights, 800w inverter, 2 x laptop computer, fridge , 8amp watermaker, no aircon or fans.

System is in balance apart from July and August when fridge duty cycle is heavy or if we make heavy use of watermaker.

Future plans would be to increase Solar to around 240 watt plus.
 
I would say that we're not particularly heavy power consumers - we rarely sit watching DVDs nor have the stereo playing for hours - but this works for us:

10.7m sailing boat
12v
300 AH domestic wet batteries
135 watts solar
Standard Yanmar alternator on the engine

One Vitifrigio self contained compressor fridge.
300 watt inverter
Led bulbs to anchor & masthead and 50% of the interior lights, the nav/steaming lights and rest of internals are incandescent/halogen bulbs
Electronic autopilot (and Windvane steering)
A fairly standard complement of electronic nav gear
chartplotting done on a laptop via the 12v system
Rarely used radar
Typical Car type CD/radio
VHF
PC

We have a Sterling smart-alternator regulator which we took off the last boat somewhere, but I've not got around to fitting it yet and probably won't bother. We left Missalonghi mid-March, are now in Rabat and over the season we've twice started the engine for a twenty minute battery boost - both after about five successively cloudy days on anchor; even on our rare visits to a marina, if the electricity is charged extra, we don't bother to connect.
