The need for renewable energy had seen a northward trend since the first time since the beginning when man realized that fossil fuels are depleting at an alarming rate. Renewable energy can be classified as energy which comes from any of the natural resources namely; sunlight, rain, wind, tides and geothermal heat. Such energy can be replenished naturally and has no dependence on any human activities. As per stats available, the use of wind power is increasing at an annual rate of 20%. These stats might not be enough to show the rise in the use of renewable energy around the globe, but then they do show that the human race is seriously looking at alternative sources of energy.

Solar power or solar energy is one the widely used source of renewable energy that is being used at various places around the world. The sun’s radiation is used to generate energy and the same can be done either in an active manner (using photovoltaic) or in a passive form (using concentrated solar power). These concentrated solar power projects have been operational since the early 1980s with the largest solar power project being installed in the Mojave Desert, California.

So, in a nut shell. This is how to use SMA inverters the most efficient way. Solar power is the conversion of solar radiation into electricity. Now, how can one do that. The answer to this would be by using inverters or better SMA inverters that are used with the photovoltaic solar cells for converting the solar power to electricity.

These SMA inverters converts the direct current (DC) to alternating current (AC). This alternating current can be kept at the required voltage and frequency by the use of transformers, control panels and switches.

A solar inverter or an SMA inverter can be attached to a commercially used electrical grid or with any off-grid electrical network. These inverters are specifically designed and are adaptable for use with photovoltaic arrays and include maximum power point tracking with anti-islanding protection. These inverters are useful as this electricity that is generated can be used for heating of ordinary household and also commercial appliances.

These inverters can be classified into 3 types, namely; Stand-alone inverters, which can be used with an isolated system by drawing energy from the batteries charged by the photovoltaic system; Grid-tie inverters, which are created to stop working automatically when the utility supply stops and cannot provide with any power back up in case of a utility outage; Battery Back-up inverters, are the special category inverters used to draw power from a battery while managing the charging of the battery and also transferring excess power to the utility grid.
