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 9.3 mm or 2/0 AWG) to fit your
Inverter/Charger's DC Input terminals (see table below). 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 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.
Maximum Recommended DC Cable Length
• Connect Fuse: NEC (National Electrical Code) article 551 requires that you connect all of your Inverter/Charger's positive DC Terminals
directly to a UL-listed fuse(s) and fuse block(s) within 460 mm (18 inches) of the battery. The fuse's rating must equal or exceed the
minimum DC fuse rating displayed on the Inverter/Charger's nameplate. 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.
Your Inverter/Charger/s Nominal DC Input Voltage must match the voltage of your battery or series string of batteries. In a series
connection, your Inverter/Charger's Nominal DC Input Voltage must match the number of batteries multiplied by their voltage. For
example, a 24V DC Inverter/Charger would require either two 12V batteries connected in series (24 = 2 x 12) or four 6V batteries connected
in series (24 = 4 x 6).
