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.

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.
