DC Connections for Stacked Inverters

Freedom SW-RVC Installation Guide

Series Stacking Operation

The inverter is designed to accept power input from a single-
phase, three-wire 120/240-volt AC system with 120 volts to each
inverter. The input line (INPUT L or 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.

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 L or L1) terminals of the
stacked pair.

Stacked inverters will typically support about twice the surge
power of one standalone unit. For example, a stacked pair will
surge about 12000 watts.

DC Connections for Stacked
Inverters

Use individual overcurrent devices 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 12 inches (30.48 cm).

Connect the stacked system as follows:

1. Connect each negative terminal to the battery.
2. Connect a Grounding wire to the common negative.
3. Connect each positive terminal of the inverter to the battery

through a DC disconnect and fuse combination or a DC
breaker in each positive line. Do not tie the positives
together between inverters.

4. Connect the 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.
