For default settings, see “Grid Support Menu” on page B–5.
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 3–28.
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.
