Battery Connection
Connect your Inverter/Charger to your batteries using the following procedures:
•Connect DC Wiring: Though your Inverter/Charger is a
high - efficiency
converter of 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 00 gauge) 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 of time. Heavier gauge cabling should be used when continuously operating heavy draw equipment under these conditions. Tighten your Inverter/Charger and battery terminals to approximately 3.5
page for Minimum Recommended Cable Sizing Chart.
•Connect Ground: Using an 8 AWG wire or larger directly connect the Main Ground Lug to the vehicle’s chassis or earth ground. See the Feature Identification section to locate
the Main Ground 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 all of your Inverter/Charger’s positive DC Terminals directly to a fuse(s) and fuse block(s) within 45 cm of the battery. The fuse’s rating must equal or exceed the Minimum DC Fuse Rating listed in your Inverter/Charger’s specifications. See Specifications for fuse and fuse block recommendations. See diagrams below for proper fuse placement.
WARNING! • Failure to properly ground your Inverter/Charger to a vehicle’s chassis or 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.
Non-Vehicular or Vehicular Applications
In a series connection, your Inverter/Charger’s Nominal DC Input Voltage must match the number of batteries multiplied by their voltage. Your 48V DC Inverter/Charger requires either four 12V batteries connected in series (48 = 4 × 12) or eight 6V batteries connected in series (48 = 8 × 6).
In vehicular applications, your Inverter/Charger’s Nominal DC Input Voltage must match the voltage of your battery or batteries— 48 Volts. Although it is possible to connect your Inverter/Charger to the main battery within your vehicle’s electrical system, in the normal vehicular context, the Inverter/Charger is connected to one or more dedicated auxiliary (house) batteries which are isolated from the drive system to prevent possible draining of the main battery.
