Cos Phi Mode changes the power factor of the export power from unity to Cos End
Power Factor
as the export power increased from 50% to 100% of the maximum export
power limit of the SP PRO.
DRM
Mode allows the charge power from the grid and the grid export power to be
controlled by a DRED device. See AS4777.2-2015 for more details. All DRM modes are
available.
DRM Source allows the DRM to be controlled by a DRED device plugged into the
SP PRO DRM socket (DRM Hardware) or by a software interface allowing the DRM
function to be controlled by writing directly to the SP PRO DRM memory location (DRM
Memory).
DRM 3 Reactive Power. When DRM 3 is active, the SP PRO will source reactive power
as a percentage of the SP PRO’s 25°C power rating, according to this setting.
DRM 7 Reactive Power. When DRM 7 is active, the SP PRO will sink reactive power as a
percentage of the SP PRO’s 25°C power rating, according to this setting.
The Power factor / Var settings are from the Network’s perspective.
As the grid voltage falls below the
Leading Var Start Voltage
, the vars
generated by the inverter start to increase. This normally has the effect
of increasing the grid voltage in a weak grid.
As the grid voltage rises above the Lagging Var Start Voltage , the
vars absorbed by the inverter increase. This normally has the effect of
reducing the voltage in a weak grid.
Max Leading Var and Max Lagging Var are the vars produced by
the inverter when grid voltage reaches Leading Var End Voltage
and
Lagging Var End Voltage
respectively, and are entered as a
percentage of the 25°C power rating of the SP PRO.
