If the inverter does not have a display, it is advisable to use the values
which are recorded by the Solar-
Log™ from a period over a week.
That is why it is recommended to leave the default PAC correction factor
at 1000 initially.
The correction factor can be adjusted yearly after receiving the state-
ment from the utility company.
