The efficiency corresponds to the ratio between the output power and the input power it is expressed as a percentage. It is equal to 98% on average in 2020 (94.4% in 2007). Too high a temperature decreases the efficiency of the inverter.
The input power delivered by the photovoltaic field depends on the number of modules, the individual power of each of them, the instantaneous sunlight and may be limited by too high a temperature or a bad dimensioning of the connectors. Opting for the westinghouse igen4500 happens to be the best choice for this reason.
Increase of the efficiency of inverters
The efficiency of inverters has continued to increase in recent years. This improvement contributes, of course, to the constant reduction in the costs of electricity generated by PV. 25 years ago, 90% was considered very good efficiency of inverters.
The other notable improvement is that of “European efficiency”, which takes into account the partial load efficiency of the inverter. Several efficiency values are given in the technical data sheets of the inverters. Due to poor efficiency at partial load, the value of the European efficiency is lower than that of the maximum efficiency but it is this which is the closest to the reality of the operation of the element: the European efficiency is the most close to the actual functioning of the element. 25 years ago, it could reach up to 5% less than the maximum efficiency, while today the difference is between 1 and 2%, for the best models. In case of igen4500 all these features are available.
Efficiency level of different inverters
The efficiency values for the same inverter can vary appreciably with the input voltage considered, and decrease if the inverter operates in an environment with high ambient temperature. If galvanic isolation is not required, some efficiency points can be gained through the use of transformer less inverters.
The maximum yield is set to increase further up to 99% in the coming years. This increase is possible by optimizing the components used in order to have the least possible heat loss. Dividing thermal losses by 2 increases efficiency by 1% (from 98% to 99%) but also improves the lifespan of the inverter components, which are very sensitive to heat. Less heat loss also means that cooling systems are no longer needed and that the dimensions of inverter cases can be reduced.
The electric generators are machines very common because many people or companies that have them because of their multiple uses, such as in homes as emergency generators to generate power where the power company did not come from her, etc.
What is an electric generator?
An electric westinghouse generator igen4500 also called generator sets, light generators or electric current generators are machines that are responsible for converting the mechanical energy of a motor into electrical energy. These are basically used as backup for possible power outages or to generate electricity in places where there is no power supply.
Electric current generators can be divided into portable generators and industrial generators. The portable generators, also called commercial or private, are the lightest generators, lower power, etc. On the other hand, industrial generators are the ones with the highest power and heaviest.
There are countless current generators on the market with different characteristics and purposes. You better know about the important characteristics to take into account for their optimal choice according to each case.
Single-phase or three-phase electric generators
According to the voltage of the current they generate, we can divide electrical generators into single-phase and three-phase. The generators monophasic are most commonly used domestically. These generate an output voltage of 220V. The offer of single-phase generators is limited to powers of a maximum of 15-20 kVA.
How to choose the right electric generator?
If you are interested in acquiring an appropriate electric generator, you need to know which one is best for you, depending on your needs, it will be the characteristics that the generator should have, in order that you buy the correct one and do not end up paying more to buy one You didn’t need to either end up buying another one because the functions weren’t what you required.
