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
‘E’
kits are available: if larger battery banks are
required discuss your individual power requirements with the boat builder or engine supplier.
•
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 150amp domestic alternator
3 x 150 = 450 ampere/hour maximum battery bank size
Example 2:
Weekend cruising or hire fleet application fitted with a 240amp domestic alternator
3.5 x 240 = 840 ampere/hour maximum battery bank size.
The standard alternators fitted to Shire engines are not suitable for charging
lithium-ion batteries. If the standard alternators are used for charging lithium-ion
batteries, they will not be covered under warranty. If lithium-ion batteries are to be
used a specialist alternator will be required.
19. Control Panel
CAUTION
All Shire engines are supplied with an engine control panel that shows RPM and hours run
and include warning lights and a warning buzzer. The deluxe panels also have additional
gauges for the water temp, oil pressure and battery charging. The panels are designed to be
splash proof and are correctly installed with the gauges vertical. Do not install so that they
remain out in the open, or cover up when not on use.
The control panel engine tachometer is supplied already calibrated to measure correct engine
