The brands of inverters tested were the famous blue gate inverters and
luminous inverter technologies. The tests carried out were repeated
severally to obtain correct values. Basic tests carried out include:
Variable load test
Constant load over time
Idle test
Night time power consumption
Generally, all tests were grouped into:
Test for input characteristics
Test for output characteristics
Protection test and other special tests.
The
wave form of both inverters were also observed on an oscilloscope, and
comparisons were made and recorded in chapter five (5) of this report.
The harmonic distortions were observed but not measured.
Limitations of the study
Within
the course of this project, certain problems/constraints were
encountered. Some of these problems/constraints encountered marginalized
the area under study while others prevented the complete carrying out
of certain tests/test procedures. Some of these problems include:
Poor
state of equipment; some analogue measuring equipment like the high
range ammeter available was improperly damped, making it almost
impossible to read instantaneous values of current.
There was a
shortage in the availability of high range measuring equipment at the
school lab. This restricted tests carried out to lower values. Certain
tests had to be attenuated or completely stopped when the values
obtained exceeded the deflection of analogue meters, or the range of
digital meters.
Unavailability of certain measuring equipment like
the THD analyzer used in the measurement of harmonic distortion.
Computer programs like the PV array simulator, required to carry out
MPPT performance test was also not available.
As a result of shortage
in certain measuring equipment, the data collected were from various
measuring instrument ( analogue, digital), leading to a non-uniform
measurement
Unavailability of standard connecting cables
The duration for the study, when compared to the volume of work required for completely carrying out the project was limited.
We also had inadequate financing as at the instant it was required
