Injecting formidable voltages proceeding from scorching and bright sunny days via your exterior into the classic electrical installation that feeds the habitable sockets where your children live and step throws an understandable insecurity at the beginner. "This could ignite on my roof". Let's clear up that fatalism.
Spanish ITC Technical Regulations
A CE-approved panel will never explode or cause unheard-of fires because it is rigidly insulated from origin against moisture filtration and thermal recess. To fully equip the installation and adhere faithfully to the official mandatory electrical directive in homes (National REBT), at Serenovables, an Intermediate Independent Board is installed: "The Photovoltaic Protections Combiner Box".
It features both a Direct Current side from the roof, and an Alternating Current side down on the floor facing resettable fuses, Permanent and Intra-storm Surge Disconnectors (Pole Arresters that shield blazingly fast in case a lightning bolt blasts the municipal external street lines, instantly blocking fatality towards household appliances safeguarding safely on the spot). It is impregnable, fireproof, and operates as your perpetual electronic bulletproof vest.
