Forexample, a 48V DC Inverter/Charger requires either four 12V batteries connected in series (48 = 4 × 12) or eight 6V batteries
connectedinseries(48=8×6).
Contact Tripp Lite technical support for assistance with additional parallel, series or series/parallel connections.

Battery Connection
• Connect DC Wiring: Though your
Inverter/Charger is a
high-efficiency
converter o f
electricity, its rated
output capacity is
limited by the length
and gauge of the
cabling running from the battery to the unit.
Use the shortest length and largest diameter
cabling (maximum 9.3 mm diameter (2/0
AWG))to fit your Inverter/Charger’s DC
Input terminals. Shorter and heavier gauge
cabling reduces DC voltage drop and allows
for maximum transfer of current. Your
Inverter/Charger is capable of delivering
peak wattage at up to 200% of its rated
continuous wattage output for brief periods
oftime. Heavier gauge cabling should be
used when continuously operating heavy
draw equip ment under these conditions.
Tighten your Inverter/Charger and battery
terminals to approximately 3.5 Newton-
meters of torque to create an
efficient connection and to prevent
excessive heating at this connection.
Insufficient tightening of the terminals could
void your warranty. See table below for
recommendedcablesizingchart.
• Connect Ground: Using a 3.15 mm
diameter(8 AWG)wire or larger, directly
connect the Main Ground Lug to earth
ground. See the Feature Identification
sectiontolocatetheMainGround Lug on your
specific Inverter/Charger model. All
installations must comply with national and
local codes and ordinances.
• Connect Fuse: Tripp Lite recommends
that you connect your Inverter/Charger’s
positive DC Terminal directly to a fuse and
fuseblock within 450 mm of the battery.

MinimumDC Fuse Rating shown on your

below for proper fuse placement.

WARNING! • Failure to properly ground your Inverter/Charger to earth ground may result in a lethal
electrical shock hazard.
• Never attempt to operate your Inverter/Charger by connecting it directly to output from an alternator
rather than a battery or battery bank.
• Observe proper polarity with all DC connections.
