These deviations have a proportional effect on the derived measurements. The efficiency specified for the inverter is determined using a high-precision measuring process and represents the ratio of the output power to the input power during nominal conditions. These specifications are also verified by independent testing institutes.
The inverter''s measuring channels may have a tolerance of up to ± 4 % for DC measurements and up to ± 3 % for AC measurements (based on the respective final value of the measurement range under nominal conditions). As a result, the relative deviation may (also) be correspondingly larger if the feed-in power is low.
The inverter''s measuring devices do not meet the high standards of calibrated measurement equipment. The inverter''s measuring channels may have a tolerance of up to ± 4 % for DC measurements and up to ± 3 % for AC measurements (based on the respective final value of the measurement range under nominal conditions).
Since different machines have different frequency and voltage requirements, a circuit known as a converter is used to convert AC current from the power grid to a DC current, and then an inverter is used to convert the DC current to an AC current with the frequency and voltage required by the machinery being driven.
