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 touch-
ing/shorting the cables.
Info: DO NOT connect the DC wires from the battery bank
to the inverter until: 1) all DC/AC wiring is complete, 2)
the correct DC and AC overcurrent protection have been
installed, and 3) the correct DC voltage and polarity have
been verifi ed.
Info: 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 (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).
Also, allow at least 1” of space between the batteries to provide good
air fl ow. DO NOT mount the batteries directly under the inverter.
Info: 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. Bat-
teries 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., batter-
ies, solar, wind, or hydro) and AC power (utility power or
AC generator) are de-energized (i.e., breakers opened,
fuses removed) before proceeding.
