Table 3-5 Inverter/Charger Grid Support Settings
Setting Description
Grid Voltage
Support Enabled
Enables Grid Support when selected.
Grid Support
Voltage
Sets the level to which the batteries will be discharged when the inverter is selling
power to the grid or supporting the power grid by providing additional power to the
loads. This setting is not adjusted for the battery temperature if the temperature
sensor is installed.
Sell Enables Sell mode when selected. Grid Support must also be enabled for Sell to be
enabled. When Sell is enabled, the inverter AC output is divided between powering
loads and delivering power to the utility grid. Sell mode requires the battery voltage to
be above the Grid Supp Volts.
Max Sell Amps Sets the maximum AC amps allowed to be delivered to the utility grid from a solar
array and/or the batteries during grid-tie operation. This setting is only used if Sell
mode is enabled.
The Max Sell Amps must be less than 80 per cent of the selected AC1 breaker
setting. If set higher, the breaker setting will override the Max Sell Amps setting to
avoid tripping the breaker. Sell can be limited with both this function and with Max Sell
Power Scale Percent.
Max Sell Power
Scale Percent
Sets the sell active power percentage. The max sell power scale is 100% by default.
Sell can be limited with both this function and with Max Sell Amps.
Sell Block Start Specifies the start time after which the grid sell feature will be Blocked (deactivated).
Sell Block Stop Specifies the stop time before which the grid sell feature will be Blocked
(deactivated).
Load Shave Enables or disables the Load Shave feature. Grid Support must also be enabled for
Load Shave to be enabled. Load Shave allows the inverter to support the grid in
powering local loads during a defined window of time (set using Load Shave Start
and Load Shave Stop). When in this mode, the inverter operates until the batteries
discharge to the LBCO threshold, after which the unit reverts to AC pass-through. The
charger is automatically blocked during the Load Shave time window.
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.
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 surcharges. The inverter provides
load shaving power as long as battery voltage is above the Low Batt Cut Out setting.
Load Shave
Stop
Sets the time of day that the Load Shave feature stops operating. If Load Shave is
enabled and Load Shave Start and Load Shave Stop are set to the same time, the
inverter load shaves continuously.
