To set the real time clock
there are 2 options
Refer to DC dispatch and AC dispatch for more information
In most applications, select AC dispatch.
For multi-string models, select String dispatch.
rarely, DC dispatch is supposed to be selected.
This menu contains all parameters that affects the performance of the AC side of the PCS. Note that depending on the mode selected, the AC side parameters may not take effect, or may not be settable
There are 3 modes supported in regulating reactive power
This setpoint will take effect ONLY when Reactive power regulation mode is set to Constant PF
To regulate the importing and exporting active power of the PCS, MUST be the most important setpoint in PCS
This setpoint will take effect ONLY when Reactive power regulation mode is set to Constant reactive power
If Power change mode is set to ramp, in normal operation, the power setpoint changes, the actual import/export power will slowly change with this slope setpoint.
AKA Connect/Reconnect Ramp-up rate Upon starting to inject power into the grid, following a period of inactivity or a disconnection, the inverter will be able to control its rate of increase of power from 1 to 100% maximum current per second.
Following a trip, the Smart Inverter must delay re-energization or reconnection for a preset period of time once the voltage and frequency of the grid are within normal ranges.
This setpoint will tune the off-grid voltage within the range of ±10% of the the rated AC voltage.
there are 4 modes supported in regulating active power
there are 2 modes
Disable or enable F/VRT (Frequency Ride-through and Voltage Ride-through) functions
By enabling this option, the anti-islanding function will be activated
There are 2 options
This menu contains all parameters that affects the performance of the DC side of the PCS. Note that depending on the mode selected, the DC side parameters may not take effect, or may not be settable
The Sinexcel PCS are classed with different types
We call each string subsystem.
there are 2 modes in this option
both of the two options take effect ONLY when Energy dispatching mode is set to DC dispatch
The PCS will import/export the power at DC side, according to this setpoint This setpoint takes effect ONLY when Energy dispatching mode is set to DC dispatch, and DC operation mode is set to Constant current
The PCS will import/export the power at DC side, according to this setpoint This setpoint takes effect ONLY when Energy dispatching mode is set to DC dispatch, and DC operation mode is set to Constant power
This is the secondary under-voltage criterion. If the voltage reaches this threshold, it's critical for the ESS. the EMS must consider charging the battery at this moment.
Usually this threshold should be set 5~10V lower than end of discharge voltage
A legacy setpoint for lead-acid battery. If you are using lithium-ion battery, this setpoint MUST be the same as topping charge voltage
refer to this article battery_dis-_charge_sequence
For lithium ion batteries, the PCS will stop charging the battery when the DC voltage reaches topping charge voltage, AND the DC current reduces to end of charge current
The battery charging current (DC) will never be more than this threshold
The battery discharging current (DC) will never be more than this threshold
If the PCS is discharging, once the voltage reaches this criteria, the PCS will stop and refuse to discharge.
A legacy setpoint for lead-acid battery. If you are using lithium-ion battery, ignore this option
Another legacy setpoint for lead-acid battery. If you are using lithium-ion battery, ignore this option
When the battery is charged as the voltage is almost reaching topping charge voltage, the current will reduce. Once the current drops to this threshold, the PCS will stop charging the battery.
