For plants with total generated power not higher than 20kW such separation can be replaced by a protection generally inside the electronic control and setting system of the inverter which makes the interface or generator device open in case of val- ues of total direct component exceeding 0.

In PV plants, with power not higher than 20 kW and with maximum three inverters, to which loads for stand-alone operation are not connected, the generator device can also accomplish the function ce interface device Figure 4.įor plants with more PV generators, as a rule, the inter- face device shall be one and such as to exclude at the same time all cek generators, but more interface devices are allowed provided that the trip command of cri protection acts on all the devices, so that an anomalous condition detected by a single protection disconnects all the generators.

Testimonials of the strong desire to meet the needs of the customer by Geotech Engineering, in this case were used pieces specially designed for integration on greek surfaces. As regards the opening command of the main device due to the intervention of the main protection, an undervoltage coil must be used because if, for any reason, the supply voltage of the main protection lacks, the opening of the main device occurs also in case of absence of the com- mand coming from the main protection.įor installations up to 20kW the cek function can be carried vei by more different devices up to 3 Guide for the connection to the electrical networks by Enel Distribution. You just have to have a space available on your home roof and all the rest we think of. Crotone Snam projects Example of collaboration with a large Italian company, Geotech Engineering cares for the maintenance of a photovoltaic plant that Snam has made on the roof of the Hera Lacinia Museum, near Capo Colonna.
These sources have the great advantage of being inexhaustible and having a limited or zero environmental impact as their exploitation does not produce either greenhouse gas or polluting waste to dispose.

In addition, the study of the most appropriate solution has always been linked to the verification of a financial plan based on available incentives or lower consumer spending. Two projects that represent a fruitful collaboration between Geotech Engineering and people of public interest are the Data transmission of the power line patented RS Modbus data transmission. Renewable energies Alternative energy is a form of energy derived from sources that, according to a human perspective, are 8-225 likely to run out, that is, they are regenerated constantly, for example, solar, hydroelectric, wind energy, energy from wood wood, biogas and geothermal energy.
This project envisaged the reclamation of the main office building cover, through the complete removal of the asbestos cement that constituted it, and the new covering with the integrated installation of Sanyo Hit HDE4 photovoltaic modules. Read more This project has foreseen, on a pre-existing sheet metal roof, the installation of the photovoltaic solar field to be plotted to the ground and integrated into it.
