Stacking Features
DC Connections for Stacked Inverters
Use individual overcurrent devices between the battery
positive and each inverter. Keep cable lengths to the two
inverter/chargers the same in order to balance cable losses. If
not, the battery cable difference in length between the two
inverter/chargers should not exceed 12 inches (30.48 cm).
Connect the stacked system as follows:
1. Connect each negative terminal to the battery.
2. Connect a Grounding wire to the common negative.
3. Connect each positive terminal of the inverter to the
battery through a DC disconnect in each positive line. Do
not tie the positives together between inverters.
4. Connect the Ground bonding wire from each inverter to
the same location on the vehicle chassis. Use that same
length and gauge wire for both inverter/chargers.
5. Connect the battery temperature sensors (BTS), if needed.
