Are you interested in installing solar inverters? Are they intended for domestic purposes or industrial
purposes? Whatever be the reason, it is one of the wisest investment decisions one can take when
it comes to electricity. Solar inverters have been very vital in contributing to the generation of
electricity through the non conventional means these days.
Right from the days of using solar cookers solar energy is one of the most sought after source of
energy to generate electricity and be put to use. The reason for solar energy being so wanted is that
it is absolutely free and available almost anywhere. In countries like India, most places are scorched
by the sun almost throughout the year.
Solar based devices can be initially costly. The infrastructure is sophisticated and hence warrants
more money. On the long run, it indeed saves a lot of money and can indeed be a promising source
of energy till the sun exists.
Though solar power is abundant and is available in all parts of the world, its intensity keeps varying
on a daily basis as well as during the year. The current generated by the photo voltaic cells present
in the inverter component will vary according to the intensity of the sunlight at the moment. The
power produced will be maximal during full solar radiation and will be minimal on cloudy and rainy
days. The nominal or the peak power mentioned on the inverters is the power generated during full
solar radiation.
Maximum Power Point Tracking is the solution
As mentioned before the intensity and the voltage of the current produced can differ. The direct
current of higher voltage produced needs to be conditioned to the direct current of voltage that can
charge batteries which serve as the storage or the voltage that can correspond to the utility grid.
Maximum Power Point Tracking (MPPT) charge controller does just this. They are different from
the controllers that move the solar panels in accordance to the movement of the sun and track it to obtain maximum power.
What is Maximum Power Point Tracking?
Maximum Power Point Tracking is done by charge controllers and is evidently called MPPT charge
controllers. What they do is, they compare the voltage of the current produced by the panels to the
voltage of the batteries. The charge controllers then change the resistance accordingly to achieve
the optimal power output during conversion from one voltage down to the required level.
Traditionally these charge controllers performed the operations for all the panels. Now, the charge
controllers are being installed for panels individually. This would help in assessing for each panel and
overcome differences arising from manufacturing defects, shading and other such problems.
The voltage is varied according to the power produced. When the resistance is changed, the change
in current produced is monitored. The variation is continued to obtain the maximum power. The
Perturb and Observe method changes the voltage and checks if there is increase in current. This is
continued until there is no more increase. Similarly incremental conductance, current sweep method
and constant voltage methods are also employed.
