disabled.
Freq/Watt: Available when activated and operating in discharge mode. When the
actual frequency is above the point, the active power will be regulated with the ramp
rate. The ramp rate is defined as multiple of set active power per hertz that above the
above the Freq/Watt point.
PF regulate: Regulate the PF of the entire storage system.

2.5.3 De-rating
The de-rating of inverter is to avoid inverter overload or restrain potential faults. The
inverter might conduct de-rating operation in the following operating conditions:
Internal over-temperature (including environment temperature and module
temperature)
