Cheoy Lee 48' JOSS
Electrical 110v / 12v


Genset Control Panel

110 volt and 12volts for Comfort and Utility: Cheoy Lee Joss has complete 110 volt and 12 volt electrical systems. The 110 volt system is driven through either 50 amp or 30 amp shore power connections, or, an 8kw Northern Lights Generator (new in 2003).

The 12 volt system is currently powered by eight 6 volt/250 amphour batteries for a total of 1000 amp hours of 12 volt power. For off shore voyaging she has space and wiring for antoher 500 amp hours of 12 volt power. The generator is located under the cockpit for for minimal noise in the cabin area. The aft cabin mounted control for the genset is shown in the picture on the left.


8kw Northern Lights Genset

The combination of the 110v and 12v systems is managed through a 3000 watt/ 130 amp Heart Interface Inverter/Battery Charger with a Link 2000 conntrol head mounted in the electrical panel.

While at the marina or on the hard, simply plug in to either a 50 amp or 30 amp service and enjoy an unending supply of 110 volt power. While on shore power your house, engine and genset batteries are kept in opitimum condition by the Heart 3000 watt inverter/ 130 amp battery charger and refrigeration and hot water is managed automatically.

Cockpit Shore Power Connections

While off shore or at anchor, a typical "electical" day on JOSS begins with starting her 8kw Northern Lights generator. After letting it warm up a little you flip the charging switch on the electrical panel to initiate the Heart Interface battery charger. Battery management is handled by a state of the art 3 stage regulator to maximize charging speed, efficiency and battery life. The house batteries are charged at rates at up to or even above 130 amp hours while the engine and genset starting batteries are trickle charged to keep them in good shape over long layovers. As battery charging settles in turn on refrigeration, hot water and the water maker. Typically, an hour and a half later shut everything down and you are done until the following day.

After a hard day of mountain biking, swimming and scuba diving, have a HOT shower, an excellent dinner (perhaps something from the freezer). Then turn on the 110 volt "real" lamps (via the inverter) throughout the cabins for comfortable light and easy reading. Don't worry!. The 12 volt batteries will be recharged during the morning genset run. Sweet!
