Battery Bank Wiring

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.
Note: DO NOT connect the DC wires from the battery bank to
the inverter until 1) all DC and AC wiring is complete, 2) the
correct DC and AC overcurrent protection has been installed
and 3) the correct DC voltage and polarity have been verified.
Note: For optimum performance, a minimum battery bank of
200 AHr is recommended.
Depending upon the type of batteries you use in the installation (6 or
12 VDC), the batteries must be wired in series, parallel or series-
parallel to provide 12 VDC (see Appendix B - Battery Information, for
guidance on wiring batteries together). The interconnecting DC wires
must be sized and rated exactly the same as those that are 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).
allow at least 1" of space between the batteries to provide good air
flow. DO NOT mount the batteries directly under the inverter.
Note: To ensure the best performance from your inverter
system, do not use old or untested batteries. Batteries should
be of the same size, type, rating and age.
Caution: Install batteries in a well ventilated area. Batteries
can produce explosive gasses. For compartment or enclosure
installations, always vent batteries to the outside.

Inverter to Battery Bank Wiring

Warning: Ensure all sources of DC power (i.e. batteries,
solar, wind or hydro) and AC power (utility/shore power or AC
generator) are de-energized (i.e. breakers opened, fuses
removed) before proceeding.
Caution: Inverter is NOT reverse polarity protected, if this
happens the inverter will be damaged and will not be covered
under warranty.
batteries to the inverter, verify the correct battery voltage
and polarity using a voltmeter. If the positive terminal of the
battery is connected to the negative terminal of the inverter
and vice versa, severe damage will result. If necessary, color
code the cables with colored tape or heat shrink tubing: RED
for positive (+); BLACK for negative (-) to avoid polarity
confusion.
