{"id":457,"count":5,"description":"<p>24V solar panels are those with 60 to 72 cells, used in off-grid installations, motorhomes and 24-volt systems. With power outputs ranging from 150 to 400 W, they are the most versatile type: they can be used both for 24 V battery banks and, with an MPPT regulator, to charge 12 V batteries whilst making the most of all the energy.<\/p>\n<h2>300W 24V solar panel: the most popular<\/h2>\n<p>The 300 W, 24-volt panel has become the standard for small and medium-sized off-grid installations. It offers a good balance between footprint, price per watt and ease of use, and is compatible with most MPPT controllers on the market without the need for complicated set-ups.<br \/>\nTwo 300 W panels connected in parallel to a 24 V battery provide a peak output of around 600 W, which amounts to around 3 kWh on a summer\u2019s day and around 1 kWh in winter. This is more than enough to power a motorhome or a holiday cottage with moderate energy consumption.<br \/>\nWe also have the format of <strong>200 W at 24 V<\/strong>, which is useful when headroom is limited or you want to fine-tune the power without exceeding the regulator\u2019s limit.<\/p>\n<h2>You need an MPPT controller<\/h2>\n<p>A 24 V panel operates at around 30\u201337 V at its peak power output. If you connect it to a 12 V battery using a PWM regulator, you lose the entire difference. A <a href=\"\/en\/product-category\/solar-charging-regulators\/mppt-regulators\/\">MPPT controller<\/a> It converts that excess voltage into additional current: with the same panels, you get between 20 and 30 % more energy.<br \/>\nTo work out the correct size of the regulator, divide the total power of the panels by the battery voltage. 600 W on a 24 V battery bank is 25 A, so a 100\/30 will do. The same 600 W on a 12 V system is 50 A, so you\u2019ll need a 100\/50.<\/p>\n<h2>What else is needed?<\/h2>\n<p>Solar cable with the correct cross-section \u2014 check it in the <a href=\"\/en\/how-to-calculate-the-cross-section-of-a-cable\/\">Cross-section table by power rating<\/a>\u2014, MC4 connectors, <a href=\"\/en\/product-category\/solar-plate-structures\/\">mounting structure<\/a> and the <a href=\"\/en\/product-category\/electrical-equipment\/fuses\/\">protections<\/a> on the DC side.<br \/>\nIf the bank is <a href=\"\/en\/product-category\/batteries\/24v-lithium-batteries\/\">24V lithium battery<\/a>, remember to configure the regulator\u2019s charging profile: lithium voltages are different from those of lead-acid batteries.<br \/>\nTell us your power consumption and the voltage at which your system operates, and we\u2019ll tell you how many panels you need: <a href=\"\/en\/victron-support\/\">free advice<\/a>.<\/p>","link":"https:\/\/fvcomponentes.com\/en\/categoria-producto\/placas-solares\/placas-solares-24-v\/","name":"Solar panels 24 V","slug":"solar-panels-24-v","taxonomy":"product_cat","parent":395,"meta":[],"menu_order":28,"_links":{"self":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product_cat\/457","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product_cat\/395"}],"wp:post_type":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product?product_cat=457"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
