Domestic Battery Bank
Domestic battery banks that are too large create excessive loads on the domestic
alternator. Alternators running at maximum output for prolonged periods of time will
eventually fail prematurely; alternators that fail due to the battery bank being over the
maximum recommended size will not be covered by warranty.
Higher output additional alternators, or travel power kits are available; if larger battery
banks are required discuss your individual power requirements with the boat builder.
The maximum domestic battery bank is calculated using the following:
Live aboard, three times domestic alternator, maximum output current.
Weekend cruising or hire fleet use, three and a half times domestic alternator, maximum
output current.
Example 1:
Live aboard application fitted with a 140 amp domestic alternator
3 x 140 = 420 ampere/hour maximum battery bank size
Example 2:
Weekend cruising or hire fleet application fitted with a 240 amp domestic alternator
3.5 x 240 = 840 ampere/hour maximum battery bank size
