Setting Description
Grid
Support
Enables Grid Support when selected.
Grid Supp
Volts
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 Turns Sell mode on and off. 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.
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.
