AC Input Wiring
AC input to the inverter/charger can be supplied from a split-phase or dual-input
AC source such as the utility grid (power company), a generator, or the output of a
transfer switch. The inverter/charger can be operated from the following types of
120 volt 60 Hz AC sources:
• Split phase: This source type has two lines, one neutral, and one ground. The
two 120 VAC lines are 180 degrees out of phase with each other, so that the
two voltages total to 240 VAC. The voltage between each line and neutral is
still 120 VAC, and the voltage between the neutral and ground is
approximately zero.
• Dual input: This source type has two line inputs, one neutral, and one ground.
Unlike the split-phase type, the two lines are in phase (not out of phase), and
must come from the same source. The voltage between the two lines is zero.
The voltage between each line and the neutral is 120 VAC, and the voltage
between the neutral and ground is approximately zero.
• Single input: This source type uses only one line input, one neutral, and one
ground. Use line 1 (“AC Input Hot 1”) for AC input if only one line is
necessary. If only line 2 is used, the inverter/charger will not transfer power.
Wiring
requirements The type of wiring required varies according to the electrical codes or regulations
applicable to your installation. Wire size must be coordinated with the over-
current protection provided ahead of the wire involved, in accordance with the
electrical codes or regulations applicable to your installation.
The AC circuit from the AC source to the inverter/charger input should be wired
using one four-conductor cable (two lines, one neutral and one ground).
The requirements for this configuration are as follows:
Explanation of Wiring Size When the AC source is split-phase (two lines out
of phase), the currents from each line subtract in the neutral, and the neutral
current will be approximately zero if the loads are equal. For example, if Line 1 is
supplying 20A and Line 2 is supplying 15A, the current in the neutral will be 5A.
In single source input, only one line is used and therefore the neutral current will
never exceed the line current.
However, when the AC source is dual-input (two lines in phase), the currents from
each line add together in the neutral. For example, if line 1 and line 2 is each
supplying 30A, the current in the neutral will be 60A. Therefore, No. 6 AWG wire
is required.
