AC Settings

3–16
The AC Settings menu configures the voltage and frequency limits for AC line 1
(grid) and AC line 2 (generator). These are the limits at which the XW Inverter/
Charger considers input voltage qualified—that is, suitable for charging batteries
or powering loads. If the input voltage is not qualified according to these settings,
the XW Inverter/Charger transfers from using AC input to inverting.
Table 3-5 AC Settings menu
Item Description
AC Priority Sets the priority for the AC source (AC1 or AC2) for qualification and
transfer. For example, this setting allows the XW Inverter/Charger to use
a renewable energy source (such as an AC hydro generator) connected to
AC2 on a first-priority basis and use utility power only when renewable
energy is insufficient or unavailable to power loads.
In systems that use both utility grid (AC1) and generator (AC2) input,
AC Priority is recommended to be set to AC2. Assuming the generator is
intended for occasional use only, the XW Inverter/Charger will use
utility power until the generator is started.
AC1 Breaker Sets the AC1 (Grid) breaker size, based on the size of the breaker
installed on AC1. The installed breaker size must not exceed the
capacity of the upstream distribution panel. The XW Inverter/Charger
limits the maximum input current to this setting by derating its charging
current. If the connected loads exceed the AC1 breaker setting, the AC
breaker trips (causing fault F63, F64, or F65). The breaker may not trip
if Grid Support is enabled and battery voltage is above the Grid Support
Volts setting, or if Peak Load Shave is enabled and the Load Shave Time
window is active.
AC1 Lo Volt Minimum acceptable input voltage level from the utility grid.
AC1 Hi Volt Maximum acceptable input voltage level from the utility grid.
AC1 Lo Freq Minimum acceptable utility grid input frequency.
AC1 Hi Freq Maximum acceptable utility grid input frequency.
AC2 Breaker Sets the AC2 (Gen) breaker size, based on the size of the installed AC
breaker. The breaker size must not exceed the capacity of the generator.
The XW Inverter/Charger limits the maximum input current to this
setting by derating its charging current. If the connected loads exceed
the AC2 breaker setting, the AC breaker trips (causing fault F63, F64, or
F65). The breaker may not trip if Grid Support is enabled and battery
voltage is above the Grid Support Volts setting, or if Peak Load Shave is
enabled and the Load Shave Time window is active.
AC2 Lo Volt Minimum acceptable input voltage level from the generator.
AC2 Hi Volt Maximum acceptable input voltage level from the generator.
AC2 Lo Freq Minimum acceptable generator input frequency.
AC2 Hi Freq Maximum acceptable generator input frequency.
