IMPORTANT: In vehicles, the neutral-to-ground bonding
(connection enabled by the N-G screw) near the AC_OUT
terminals (as shown in Figure 12 ) in one of the inverters
(unit 1) in a series stacked configuration must be
disconnected by removing the N-G screw while leaving the
N-G screw in place in the other inverter (unit 2) to allow the
automatic neutral-to-ground switching to continue for the
series stacked pair.

Do not connect any wires to the AC INPUT L2 terminals on both units at all when stacking.
