The quality of the inverter can be measured frequently by using the VTC or voltage transfer curve, which is plotted between input voltage (Vin) and output voltage (Vo). From the following static characteristics, the parameters of devices like gain, operating logic levels & noise tolerance, and noise can be obtained.
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).
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.
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.
