The starting condition states that an analysis will take place only if irradiation (+Gi) is
within a range of 200–1,350 W/m². If the irradiation measured is below 0 W/m² or
above 1400 W/m², an error is immediately generated.

The monitoring of system efficiency (+etaPV) starts as soon as the starting condition is
met. Tolerance violations are signaled only if they persist longer than the tolerance
time for warnings (refer to section 6.2.4). The performance ratio (+PR) is evaluated
daily at 00:00 (midnight). The current value can be seen anytime on the Sunny Data
Control under “Realtime Data” or under Single Device Information in Sunny Data
Control.
