Installation
CAUTION:
The inverter is NOT reverse polarity protected (negative
and positive connected backwards). Verify the correct voltage
polarity BEFORE connecting the DC wires, or damage may occur.
Crimped and sealed copper ring terminal lugs with a 5/16” hole should be
used to connect the DC wires to the inverter’s DC terminals.

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 protection have been installed, and 3) the correct
DC voltage and polarity have been veri
fi
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 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). 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.
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. Batteries
can produce explosive gasses. For compartment or enclosure
installations, always vent batteries to the outside.
