9. INVERTER
9.1
Find a clean, dry place away from sensitive electronics
and securely mount the inverter in accordance with the
manufacturer’s specifications.
*** Inverters have large capacitors. Once connected
to 48V, they will be charged - bear this in mind when
working on the 48V system. There may be significant
residual energy stored in the inverter even after it has
been turned off**
9.2
Run in and connect the positive and negative cables
to their respective busbars. These should be fused
according to cable sizing all noted on the installation
schematic. Always keep the inverter location as close as
possible to the batteries.
*** Ensure all 240V/110V power is disconnected from the
boat, including other inverters***
9.3
Connect the AC power as described in the inverters
manual.
9.3.1
Depending on the boat setup, it may
be necessary to use different feeds to that of
a standard inverter. Some boats have two AC
circuits, one powered only by shore power
and one that can be powered by an inverter.
If you have sized the inverter appropriately,
you can connect into the shore power circuit.
This means you will be able to supply all
appliances on your boat, including the high
power consumers such as water heaters,
microwaves and cookers.
9.4
Switch the inverter on and configure the charging
profiles correctly for the battery make and model you
have. This is essential for lithium-ion batteries.
10. DC-DC CONVERTER
10.1
Find a suitable location that is clean and dry.
Mount the DC-DC converter with suitable fastenings.
10.2
Run in and connect a suitably sized positive cable
from the 48V busbar through a suitably sized circuit
breaker or fuse to the 48V positive terminal on the DC-
DC converter via the supplied switch.
10.3
Run in and connect the same sized negative cable
directly from the 48V negative busbar to the DC-DC
converter.
10.4
Run in and connect the positive and negative
cables directly to the 12/24V house ban. These cables
should be suitably sized and fused. Note that there
will be more current flowing on the 12V/24V side.
10.5
Refer to DC-DC converter installation instructions
for remote switching. With some models it may be
possible to switch the DC-DC converter without
passing all input current through a switch.
***Ensure negative cables are both connected and
commoned. A smaller busbar is useful for this***
11. SCREEN INTERFACE
11.1
Find a suitable place to mount the display screen
where it is possible to flush mount and have access to
run the cabling. It should be easy to read and reach,
and secured with appropriate fixings.
11.2
Fit the screen interface box within 200mm of the
screen, this should be semi accessible as this is the
point at which the system software can be updated via
the USB port.
11.3
Connect the screen loom between the screen
interface box white 12-way Molex plug and the two
deutsch plugs on the back of the screen. Though
the plugs have the same number of pins, they have a
different register and will only fit in the correct socket.
11.4
The supplied alarm buzzer should be connected
to the four-pin connector and mounted appropriately.
11.5
Given the screen is a relatively high
user of power, it is important that the Screen
interface box is plugged directly into one of
the ports on the controller as this is the only
power source on the Integrel CAN bus system.
