Sofar CH1000 - Reactive Power Control

Setting instructions
Percentage of active
power (%)
Set the value of the system output active power as a per-
centage of the total rated system output power.
Absolute value of active
power (W)
Set the speci󰘰c value of the system output active power.
Rate of change of active
power
Set the active power change gradient. Advanced parame-
ter, no setting is required by default.
The system power rating = the sum of the power ratings of all inverters in the
system. The rated power of each inverter can be obtained from „Rated Output
Power“ on the tab bar of inverter. Users can also add a sub-device in the local
WEB, and then get the rated power of each inverter from the “Rated power”
column in the sub-device detail page of the “Device Manage”——“Device Info”
page.
When the protocol conversion function in Section 7.6 is disabled, active pow-
er control can be performed via the CH1000’s local WEB. Once the protocol
conversion function is enabled and connected to the SCADA system, the local
WEB active power control function of CH1000 will be disabled.

Parameter name Setting instructions
Reactive power enable
On: the system reactive power will be controlled according to
the speci󰘰ed reactive power control method.
O󰘯: the system will remain in purely active output operation.
Reactive control mode
Reactive power percentage mode: by setting the percentage
of reactive power output from the system to its rated power,
it realizes dynamic regulation and compensation of reactive
power on the grid.
Power factor: the ratio of active power to apparent power
output from the system, which determines the reactive power
output from the inverter.
Reactive power mode: the inverter outputs a 󰘰xed value of
reactive power to meet the speci󰘰c demand for reactive pow-
er from the grid or load.
