DC Connections for Stacked Inverters
Individual overcurrent devices are to be used 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 30 cm. 
Connect the stacked system as follows: 
1.
Connect each negative terminal to the battery.
2.
Connect a earth (ground) 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 earth (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.
