Load Shave
Amps
Sets the maximum amount of current that can be drawn from the AC1 (grid) input by
the loads and battery charger combined. This setting determines the amperage
level at which the inverter starts drawing power from the batteries to add to the utility
power to meet the demand of the loads.
Typically, this value is set to the size of the AC circuit breakers feeding the inverter’s
AC input or the peak usage or time of day surcharge threshold imposed by the
utility, if applicable.
Load Shave Start Sets the time of day that the load shave feature operates. This feature is suited for
regions where local utilities impose peak usage or time of day surcharges. The
inverter provides load shaving power as long as the battery voltage is 2 V or more
above Low Batt Cut Out. See Figure 3-7, “Load Shave Mode” on page 3–27.
Load Shave Stop Sets the time of day that the load shave feature stops operating. If Load Shave is set
to enabled and Load Shave Start and Load Shave Stop are set to the same time,
the Conext XW+ load shaves continuously.
