Load Shedding:
The smart load is configured using time periods and/or SOC/voltage. The port will be active if within
the set time period and/or when the SOC or voltage is above the specified start value. The port will
be disabled if outside the specified time period, and/or the end SOC/voltage is below the set value.
Smart Load Start & End SOC(%): [0, 100] and [0, 100]
The smart load port is enabled when above the starting SOC and disabled when below the SOC.
Values are 0 – 100%.
Smart Load Start Volt: [48V – 59V]
The smart load port is enabled when above the defined voltage value.
Smart Load End Volt: [40V – 52V]
The smart load port is disabled when below the defined voltage value.
Smart Load Start Time: [00:00 – 23:59]
The smart load port is enabled at the defined start time. If one of the three time periods is met, the
port relay will close (power on). Range is 00:00 – 23:59
Smart Load End Time: [00:00 – 23:59]
The smart load port is disabled according to the defined end time. Range is 00:00 – 23:59
Power Shedding:
PV power is also used in the configuration when using the power shedding mode. If the “Grid
Always On” is disabled and the PV power is above the set value, the port will be enabled. If a time
period and/or battery SOC/voltage is added to the start PV setting, all defined settings must be
met for the port to be active. The port will be disabled when configured settings are outside the
defined enabled values. If ‘Grid Always On’ is enabled, and there is a grid connection, the port will
remain active regardless of PV input, time, or battery SOC/voltage.
Smart Load Use Shedding Mode: Enable | Disable
Enable: Allows the port to use PV wattage to enable or disable power to the port.
Disable: Do not use PV wattage to enable or disable power to the port.
Smart Load Power Shedding Start PV Power(W): 0 – 25.2kW
This is the low PV input threshold. When the PV input wattage goes below the set value, the port
is disabled.
Smart Load Power Shedding Start & End SOC: [0, 100] and [0, 100]
The smart load port is enabled above the starting SOC and disabled when below the SOC.
Values are 0 – 100%.
Smart Load Power Shedding Start Volt (V): [40V – 59V]
The smart load port is enabled when above the defined voltage value.
Smart Load Power Shedding End Volt (V): [40V – 59V]
The smart load port is disabled when below the defined voltage value.
Smart Load Start Time: [00:00 – 23:59]
The smart load port is enabled at the defined start time. If one of the three time periods is met, the
port relay will close (power on). Range is 00:00 – 23:59
Smart Load End Time: [00:00 – 23:59]
The smart load port is disabled according to the defined end time. Range is 00:00 – 23:59
AC COUPLE
This section describes the various AC coupling settings. When configuring AC coupling, the enablement
and start/stop settings are configured within the GridBOSS settings area of the EG4
®
Monitor Center.
There are inverter settings that also interact with the functionality of the GridBOSS AC-coupled port.
