Location Considerations

CAUTION: The inverter/
charger can weigh up to
40 lb. (18.2 kg) depending
upon configuration.
Always use proper lifting
techniques during
installation to prevent
personal injury.

• Inverters contain sophisticated electronic components and should be located in
a well-protected, dry environment away from sources of fluctuating or extreme
temperatures and moisture. Exposure to saltwater is particularly destructive and
potentially hazardous.
• Locate the inverter as close to the batteries as possible in order to keep the
battery cable length short. However, do not locate the inverter above the
batteries or in the same compartment with vented batteries. Batteries generate
hydrogen sulfide gas which is corrosive to electronic equipment. They also
generate hydrogen and oxygen. If accumulated, an arc caused by connecting the
battery cables or switching a relay could ignite this mixture. Mounting the
inverter in a ventilated enclosure with sealed batteries is acceptable.
• The mounting surface must be capable of supporting twice the weight of the
inverter.
• Mount the inverter either on a vertical surface (e.g., wall) or a horizontal surface
(e.g., shelf ).
• Use 0.25 inch (0.635 cm) lag bolts for mounting, if necessary.
• Install the inverter in a well-ventilated area/enclosure for proper operation. The
inverter's thermal shutdown point will be reached sooner than normal in a
poorly ventilated environment, resulting in reduced peak-power output and
surge capability, as well as shorter inverter life.
• Some models have an internal fan. Ensure that the air vents and intakes are not
obstructed in any way. Provide a minimum clearance of 1½ inches (3.81 cm)
around the top and sides of the inverter for ventilation.
• All wiring and installation methods should conform to applicable electrical and
building codes.
• Pre-plan the wire and conduit runs. The AC circuits accept cable sizes up to
#10 AWG. The DC circuits accept cable sizes up to #4/0 AWG.
• For maximum safety, run both AC and DC cables in conduits.
