{"id":284,"count":4,"description":"Type 1 and Type 2 Surge Arresters for PV Systems\nSurge protective devices (SPDs) for photovoltaic (PV) systems are specifically designed to protect solar installations from damage caused by surges. These surges can be caused by lightning strikes or switching operations in the power grid. There are two main types of surge protective devices for PV systems: Type 1 and Type 2.  \nType 1 Surge Arresters for PV Systems\n<strong>Main features:<\/strong>\n\n \t<strong>Protection against high lightning currents<\/strong>: Type 1 surge arresters are designed to divert direct or nearby lightning currents that may enter the PV system.\n \t<strong>Installation location<\/strong>: These surge arresters are installed in the PV system's main distribution panel, often at the point where the PV system is connected to the building and the grounding system.\n \t<strong>Lightning Current Diversion<\/strong>: Type 1 arresters can divert very high currents (10\/350 \u03bcs waveform), typically up to several tens of thousands of amperes.\n \t<strong>Standards<\/strong>: They meet the requirements of the IEC 61643-31 and EN 50539-11 standards, which were developed specifically for PV systems.\n\n<strong>Application:<\/strong>\n\n \tType 1 surge arresters are installed in PV systems located in areas at risk of lightning strikes or directly connected to an external lightning protection system.\n\nType 2 Surge Arresters for PV Systems\n<strong>Main features:<\/strong>\n\n \t<strong>Protection against indirect lightning strikes and switching surges<\/strong>: Type 2 surge arresters protect against surges caused by indirect lightning strikes or switching operations in the power grid.\n \t<strong>Installation location<\/strong>: These surge arresters are typically installed in the distribution panels and near the inverters to protect the sensitive electronic components.\n \t<strong>Energy absorption<\/strong>: Type 2 surge arresters can dissipate moderate amounts of energy (8\/20 \u03bcs waveform), typically up to 40 kA.\n \t<strong>Standards<\/strong>: They also comply with the requirements of the IEC 61643-31 and EN 50539-11 standards.\n\n<strong>Application:<\/strong>\n\n \tType 2 surge arresters are installed in PV systems to protect internal components\u2014particularly inverters and control units\u2014from damage caused by power surges.\n\nSummary\nType 1 and Type 2 surge arresters for PV systems provide comprehensive protection against various types of surges:\n\n \t<strong>Type 1<\/strong> protects against direct lightning strikes and is installed at the main feed-in point of the PV system.\n \t<strong>Type 2<\/strong> protects against indirect lightning strikes and switching surges and is installed in distribution panels near sensitive components.\n\nCombining both types ensures comprehensive protection for the entire PV system, thereby increasing the system's service life and reliability.","link":"https:\/\/www.alpha-therm.com\/en\/produkte\/overvoltage-protection\/surge-protection-devices\/surge-protection-devices-for-pv-systems\/","name":"Surge protection devices for PV systems","slug":"surge-protection-devices-for-pv-systems","taxonomy":"product_cat","parent":283,"meta":[],"menu_order":41,"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
