Electrolyte levels should be checked and topped up periodically. Installation must be carried out by a qualified electrician.\u003c\/p\u003e","brand":"Hoppecke","offers":[{"title":"12V 1 OPzS bloc Solar Power 70","offer_id":52060309160224,"sku":"147852369","price":237.04,"currency_code":"GBP","in_stock":true},{"title":"12V 2 OPzS bloc Solar Power 130","offer_id":52060309192992,"sku":"147852370","price":335.16,"currency_code":"GBP","in_stock":true},{"title":"12V 3 OPzS bloc Solar Power 200","offer_id":52060309225760,"sku":"147852371","price":456.44,"currency_code":"GBP","in_stock":true},{"title":"6V 1 OPzS bloc Solar Power 270","offer_id":52060309258528,"sku":"147852372","price":310.91,"currency_code":"GBP","in_stock":true},{"title":"6V 2 OPzS bloc Solar Power 330","offer_id":52060309291296,"sku":"147852373","price":372.65,"currency_code":"GBP","in_stock":true},{"title":"6V 3 OPzS bloc Solar Power 400","offer_id":52060309324064,"sku":"147852374","price":426.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-147852369-1.webp?v=1785487561","url":"https:\/\/www.ledandsolar.co.uk\/products\/hoppecke-opzs-vented-solar-battery","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
