Planning Preparations
AC Output
The output voltage on
$XWR3RZHU
inverter/chargers is
120Vac. The AC output line configuration depends on the
model.
•
Single AC Line models have a Single Input and Single
Output line - (SI-SO) configuration.
•
Dual AC Line models support Dual Input and Dual
Output lines - (DI-DO) configuration.
AC Loads
The
$XWR3RZHULQYHUWHUFKDUJHUVDUH
intended to power
loads consisting of 120 volts AC appliances.
In Invert mode, the
$XWR3RZHU
connects L1 and L2 output
lines together to provide 120 volts AC to loads on either line.
In AC Bypass mode, the source connected to the AC input is
passed through to the load. Because of the way invert mode
operates, only 120 volts AC appliances can be connected to
the
$XWR3RZHU
output.
AC Disconnect and Over-Current Protection Device
To meet CSA, UL, and electrical code requirements, and to
protect system wiring, the AC inputs and outputs of the
inverter/charger must be provided with overcurrent protection
on both the AC input and output. This protection may be a
circuit breaker or a fuse with a disconnect device (for
simplicity the following refers to breakers). Refer to your
applicable installation codes and the following requirements:
AC Input Protection
The breakers protecting the AC input of the
$XWR3RZHU
must be approved for use on 120 volts AC branch circuits,
and must be located in each Line. The breakers must be rated
as shown below:
•
Split-phase input
: No more than 30 amps max in each
line.
•
Dual input
: The neutral current in a dual-input system is
the sum of the two line currents, and must be limited to 60
amps maximum to protect the transfer relay in the
$XWR
3RZHU
. Each breaker must not exceed 30 amps,
and the
total (sum) of the ratings of the two breakers must
not
exceed 60 amps.
