Setting dBuf to 1.000 Hz is the limit of the range of adjustment in this inverter model. Setting the value to this limit partially disables
frequency-droop under-frequency response. HECO 14H does not require under frequency response, see Figure 4 of HECO 14H, where
frequency response is flat below 60 Hz.

Only one of the four VAr functions (
Volt/VAr
,
Watt/VAr
,
Constant PF
,
Constant VAr
) can be enabled at one time.

The published requirement in HECO 14H is 0.33 % / s. A value of 1/0.0033 = 303 seconds.
