Series Stacking Operation
The pair of series stacked inverters is designed to accept input power from a single-phase, three-wire 120/240-VAC system with
120 volts to each inverter. The input line (
INPUT L1 ) terminal of each inverter accepts one leg of 120 volts each and the input
neutral ( INPUT N ) terminals of both inverters are tied together and connected to the power source neutral leg. The protective
ground conductor of each cable is connected at both of the inverter input ground ( INPUT G ) AC terminal connectors.
Any AC load being powered while AC input is present to the inverters will be in addition to the power being drawn for charging the
batteries. Each unit in the stack can provide a full pass-through current of 30 amps for 120-volt systems.
When AC input power is lost, both units in the stack switch from charger to inverter mode. Once this switch is made, 120 volts AC
is available from each individual inverter or 240 volts AC is available across the output line (
OUTPUT L1 ) terminals of the stacked
pair. This kind of synchronization is possible when the Sync cable is attached to the Sync ports on the paired units.
Stacked Freedom EX 4000 inverters will typically support about twice the surge power of one standalone unit. For example, a
Freedom EX 4000 stacked pair will support a surge of about 16 000 watts.
