Battery Connections for Stacked Inverters
When using inverters in a stacked configuration, the same battery bank must be
used for both inverters. To ensure even charging of the batteries, each inverter
must be connected to both strings (i.e., positive cable to string two, and negative
cable to string one for inverter 1, and positive cable to string one and negative
cable to string two for inverter 2) as shown in the diagram below.
