ELECTRICAL SYSTEM
The Dragonfly 1000 has a 12V DC electrical system with a 110V AC system (shore
power). The DC system is based on three 65 amp 12V batteries. These batteries are
located under the bottom step in the companionway. The batteries are controlled by
the switch panel above the step. Of the three batteries, one is designated for the
Engine only and the other two are both used for auxiliary power. All three batteries
can be connected through the emergency switch on the battery control panel. The
control ports have three switches, Engine, Emergency, and Auxiliary
The
engine battery
is connected only to the engine
The
auxiliary battery
is connected only to the auxiliary system.
The
emergency battery
can be sent to the engine or auxiliary panel by switching on
the on the emergency battery switch.
Charging the batteries: There are three possible ways to charge the batteries:
1.
Run the engine
: The engine has a 55 amp alternator which will charge the engine
battery until it is full. Once it is full, it will then switch to the auxiliary batteries.
2.
Solar Panels
: The two 50w panels put out a total of 8 amps. They are linked to a
regulator, which is located behind the auxiliary panel. The regulator then sends the
power to the auxiliary battery.
3.
Shore power
: The shore power system comes with a 10 amp charger located
behind the refrigerator. It charges the two auxiliary batteries. The charger has an
automatic shut-off switch which will prevent the batteries from being over charged, but
if the boat will be left unattended for several weeks, we do not recommend having the
system on.
**NOTE** Shore power will charge only the auxiliary batteries, unless the
emergency switch is on then it will charge all three batteries.
