3.2.4 Active Power Response
The inverter supports two power quality response modes, which can be set via the
LCD menu. For details, see “12.3 Active Power Response”.
y
Volt-watt:
Define the response curve with four reference voltage values. The inverter power
output or input will vary in response to the voltage curve.
y
Volt-watt (Charging):
When the power from the grid is required to charge the energy storage system,
the import power from the grid varies in response to the grid voltages. The
response curve is defined by the voltage reference values and the corresponding
power consumption from the grid for charging energy storage.
y
Frq-watt:
Define the response curve with a start frequency and an end frequency. The
inverter power output or input will vary in response to the increase or decrease
in grid frequency.
3.2.5 Load Control
The inverter provides a load control dry-contact (DO1 relay), which can control the
load via a contactor. Refer to “6.8 DO Connection” for the cable connection.
User may set the control mode according to individual demand. Refer to “10.7.7
Setting Load Control” for LCD s ettings.
Timer: Set the starting time and end time. The DO function will be enabled during
the interval.
ON/OFF: The DO function will be enabled if ON or disabled if OFF.
Optimized: Set the starting time, end time, and the optimized power. During the
interval, when the export power reaches to the optimized power, the DO function
will be enabled.
3.3 Battery Management
The following kinds of batteries are compatible with the SH5K PV ESS.
y
Li-ion battery from Sungrow, LG Chem, GCL Pylon, BlueSun and BYD.
y
Lead-acid battery from Narada (which has a pre-set setting) or others (which
require manual configuration).
