2.0 Installation
2.4.5 Wiring the Battery Bank
WARNING:
Lethal currents will be present if the positive and
negative cables attached to the battery bank touch each other.
During the installation and wiring process, ensure the cable ends
are insulated or covered to prevent touching/shorting the cables.
Info:
DO NOT connect the DC wires from the battery bank to
the inverter until 1) all DC wiring is complete, 2) the correct DC
overcurrent protection has been installed, and 3) the correct DC
voltage and polarity have been veri
fi
ed.
Depending upon the voltage of the batteries (6 or 12 VDC), the batteries
must be wired in series, parallel, or series-parallel to provide the correct
voltage. The interconnecting DC wires must be sized and rated exactly the
same as those used between the battery bank and the inverter.
Place the batteries as close as practical to the inverter, preferably in an
insulated and ventilated enclosure. Allow adequate space above the batteries
to access the terminals and vent caps (as applicable). Also, allow at least 1”
(2.5 cm) of space between the batteries to provide good air
fl
ow. DO NOT
mount the batteries directly under the inverter.
CAUTION:
Install batteries in a well ventilated area. Batteries
can produce explosive gasses. For compartment or enclosure
installations, always vent batteries to the outside.
Info:
To ensure the best performance from your inverter system,
batteries should be of the same size, type, rating, and age. Do not
use old or untested batteries.
2.4.6 Appliances and Run Time
The CSW Series inverters can power a wide range of household appliances
including small motors, hair dryers, clocks, and other electrical devices.
As with any appliance using batteries for power, there is a certain length
of time that it can run—this is called “run time.” Table 2-3 below provides
estimates of power consumption and run time for various appliances using a
12V-120AH battery bank.
