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.
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 protections 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" (2.5 cm) of space between the batteries to
provide good air fl ow. DO NOT mount the batteries directly under
the inverter.
