Solar energy is already the most efficient energy source<\/strong> in many markets and is expected to be the low-cost technology of choice in many more by 2030. Despite the impact and uncertainties caused by Covid-19, photovoltaic energy is expected to expand its current market share by a seven-fold increase in capacity and potential,<\/strong> according to a report done by DNV. Significant solar capacity growth was recorded in 2020 in China (49 GW), USA (15 GW), Vietnam (11 GW) and Japan (5 GW).<\/p>\n

Which are the most critical components of a Balance of System (BOS)?<\/strong><\/span><\/h3>\n

SOLAR INVERTER<\/strong><\/span><\/h3>\n

It is an indispensable element in any photovoltaic installation, whether on-grid-connected or off-grid. There are two kind of inverters:<\/p>\n

    \n
  1. string inverters<\/em><\/strong>, smaller inverters installed close to the PV panels<\/li>\n
  2. central inverters<\/em><\/strong>, which centralize a larger number of PV panels.<\/li>\n<\/ol>\n

    \u00a0<\/strong>COMBINER BOX<\/strong><\/span><\/h3>\n

    Since the voltage for a single panel is too low, several panels are connected in series to provide an output voltage within the inverter\u2019s working ratings (usually 1000-1500Vdc , with grid network output up to 800Vac).<\/p>\n

    A combiner box is composed of: Switch-Disconnector, protection against short circuits, surge arresters and, optionally, monitoring systems.<\/p>\n

    ISOLATION SOLUTIONS <\/strong><\/span><\/h3>\n

    The <\/strong>switch disconnector must operate in accordance with the voltage<\/strong>, and guarantee a safe and effective load break. For short-circuit protection, fuses specific for this sector with high breaking capacity must be installed.<\/p>\n

    S7, the leading switch for photovoltaic sector<\/span><\/a><\/h4>\n\n\n\n
    \"\"<\/a><\/td>\nThe S7 Series of Telergon is a new 2P high performance switch-disconnector capable of reaching 500 A – 1500 Vdc<\/strong> (750 Vdc per pole). Based on the innovative MAGIC patented technology, S7 is the result of years of research of our R&D team and the expertise provided by our successful experience being the preferred DC switch-disconnector supplier for solar plants.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
