ELECTRICAL CONNECTIONS TO ALTERNATE POWER SOURCES
During the day the gyro stabilizer will be powered from the generator but at night the generator
will be turned off and the gyro stabilizer will be powered from the boat’s battery system. Can this
be accomplished?
While the gyro stabilizer can be operated overnight on a battery system, it will not be practical on
most boats due to the large battery pack required. To provide power overnight (8 to 10 hours) for
the gyro stabilizer requires a 24 VDC deep discharge battery pack with a capacity of at least 1700
Amp-hours. A battery pack of this capacity will weigh approximately 1000 Kg (2200 lbs) and take up
over 2.3 m2 (25 ft2) of space. It will also require the addition of a marine inverter with the
following capabilities:
Input: 24 VDC
Output: 230 VAC, 15 A, 3 kW
Figure 7 shows a configuration that would allow the gyro stabilizer to be switched from generator power
to inverter power. Note that the batteries and inverter shown are required just to power the gyro
stabilizer for 8 to 10 hours. Any other DC loads on the boat would require additional battery capacity.
This system will also require a battery charging system capable of recharging the battery pack from the
boat’s generator.
