Interface panels
for Photovoltaic
All photovoltaic systems need to be connected to the electrical system in order to operate.
But what do we mean when we talk about Interface Panels for Photovoltaics?
What are interface frameworks
All photovoltaic systems need to be connected to the electrical system in order to operate.
The definition of electrical interface switchboard is used to refer to that category of switchboards designed to operate facilities made to produce electricity and deliver it to the grid.
If power generation is through a photovoltaic system, the electrical interface panel will have to be made according to special features and specifications:
– Based on the needs of the specific plant user;
– In compliance with current regulations on the Connection of Active and Passive Users to the BT Network.
According to CEI 0-21 Ed. 2016-07 standard, installations connected to the LV national power grid, if greater than 11.08 kw in power, must be equipped with an external grid interface, compulsorily. For lower power systems, the inverter’s internal interface protection is sufficient, if it complies with the standard.
All frameworks are composed of primary brands:
– tetrapolar disconnect switch (general switchboard) complete with any release coil for systems above 20kWp for back-up control as required by current regulations;
– Three-phase 20 kA surge arrester with related protection;
– interface relay complying with CEI 021 and CEI 0-16 standards, equipped with quick-fuse protections on the three-phase input line to the SPI and on the SPI power line;
– interfaces are set with default values provided by the standard, with the possibility of customization upon request;
– contactor sized with flow rate in AC3;
– Residual current circuit breakers of suitable rating, 6 kA 300 mA class A breaking capacity for protection of each inverter;
– Carpentry made of metal or thermoplastic material with IP65/IP66 degree of protection, resistant to dynamic and atmospheric agents;
– screen-printed indicator plates and wire and terminal numbering system, terminal blocks, and any other charges for the proper assembly of the switchboard.
