Calculating the Deviation for Inverter 1
Inverter 1 IRV calculation
Efficiency of Inverter 1
corresponds to 71.81 % of the generator power or a value of 0.7181 kWp.
IRV Inverter 1 - IAV Inverter 1
Deviation as a percentage
Inverter 2 is used as the reference inverter since it was the most effec-
tive one at the time of the measurement. Inverter 1 should have pro-
duced an output of 4916 W based on the measurement and the calcula-
tions comparing all of the inverters in the same module field. The actual
output was 3950 W, a deviation of 19.65%. This caused a notification to
be sent.

Deviation Calculation
(5500*89.39): 100= IRV 4916 W
(3950 W: 5500 W)* 100= 71.81 %
Deviation as a percentage
4916 W – 3950 W= 966 W
(966 W: 4916 W)* 100= 19.65 %
