5.6.6.2 Ramp Rate Limit
This function is used for changing power ramp up rate.
When the inverter initializes or string MPPT changes, the ramp up rate is limited.
The default setting is stop
(disable).
The setting range is from 10% to 600%, This will change the power change rate per minute.
If these values are changed the inverter may not conform to UL 1741 SA or IEEE 1547
standard
.
5.6.6.3 Freq Derate Set
Mode 04 is used for UL 1741 SA frequency derating.
Mode 08 is used for Rule21 frequency derating.
Within this mode the user can set the frequency start, stop points, etc,.
This setting is applicable when UL Standards are selected.
