INTERVER, THE HEART OF THE PHOTOVOLTAIC SYSTEM
The inverters are the heart of the photovoltaic system, they are like the engine for the car, having a nice car or a sports car and then not having a high engine only serves to mortify the performance of the car.
The same goes for a photovoltaic system, making an accurate design, making an excellent installation with quality structures, cables and quality connections, modules with excellent performance and then buying unsuitable inverters means that what on paper is excellent Plant becomes a poor plant in performance.
The inverters, whether they are string or central, therefore from 1 kw to 2 mw or higher almost all have very similar performance performances by reading the sheet technique that the Manufacturer provides, in reality then a lot of other information must be added to that single data, the behavior of the inverter al vary in the temperature first of all, because the efficiency data is established with the best possible conditions, conditions that are Unlikely they will find in the environment in which the system will then be mounted.
So you need to understand the type of reaction to heat or cold, Italy has a rather different range of temperatures, just think of Sicily
or to Sardinia and to the north of regions such as Valle d’Aosta or Trentino, where temperatures are reached in winter that are not possible in Sicily not even found in the temperature scale.
Then, to all the accessories that may or may not be standard in an inverter, such as the transformer, the disconnect or the fuse that often must be purchased separately in the cheaper inverters.
Many designers when designing a system have doubts whether to use a large central inverter or several medium power inverters, does not exist a right answer or a wrong answer, both solutions have advantages and disadvantages, starting with the cost, a power inverter higher costs almost always less, on the other hand smaller inverters give greater flexibility of use, but these are subjective choices.
What is certain is that a good product is always better than a mediocre product even if the latter saves something, it is a
a difference that will then be counted in production and in all situations in which assistance will be needed, that’s why we decided
to distribute only market-leading products with assistance in Italy or in Europe such as Ingeteam, Sunway, Huawei, Kaco, ABB and others.
