Description
Arc fault circuit interrupter (AFCI)
Amplification of the anti-island
process
Repetition rate of the anti-island
process
The Sunny Boy evaluates the yield
and displays the approximate
amount of CO2 that the Sunny Boy
has saved.
This CO2 amount is calculated by
multiplying the generated kWh (E-
total) by the factor defined in the
parameter "CO2".
