Manual ON and OFF input is read on the inverter digital input. When +R and –R are
shorted the inverter shut off. When set to OFF, the display will cycle through the
following screens:
To shut ON the inverter is necessary removing the short between +R and –R.
5.4.6.11 UV Prot.time
This function is used to set the inverter connection time after the input voltage drops
below the Under Voltage limit, set at 90V.
For example: If UV Prot.time is set at 60 seconds, and Vin voltage drops below 90V at
9.00 hrs, the inverter stays connected to the grid (at 0 power) up to 9.01 hrs.
Power-One sets this time at 60 seconds. The user can change this setting and set it
from 1 second to 3,600 seconds.
5.4.6.12 MPPT
This function is used to automatically set the parameters for the Maximum Power
Point Tracker function.
1) MPPT Amplitude: Set this parameter to choose the amplitude of the disturbance
introduced in DC in order to establish the optimal work point. There are 3 options
(LOW, MEDIUM, HIGH). The default setting is LOW.
2) It can be set by enabling or disabling the scan function to detect the maximum
multiples.
