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.
